From 3aa0904922cff1903df0ca68701d9fb85d72cd2c Mon Sep 17 00:00:00 2001 From: PhiLia011 Date: Sun, 20 Sep 2026 12:39:16 +0800 Subject: [PATCH 01/10] feat: add prompt injection guard and persona/language anchor Adds two optional protections to the main agent, both disabled by default: 1. Prompt injection guard Detects attempts to hijack instructions, leak the system prompt, jailbreak, forge chat delimiters, or bypass filters via zero-width / base64 obfuscation. Strategy is configurable: block / sanitize / warn / log. 2. Persona & language anchor Re-asserts the persona after tool calls and structured-data handling so the model stops drifting back to "as an AI assistant", and optionally pins the reply to a single language to avoid Chinese-English mixing. Both are off unless explicitly enabled via the persona config block, so existing behaviour is unchanged. Covered by 52 new unit tests; the existing 139 main-agent tests still pass. --- astrbot/core/astr_agent_tool_exec.py | 12 + astrbot/core/astr_main_agent.py | 130 ++++++++ astrbot/core/astr_main_agent_resources.py | 19 ++ astrbot/core/config/default.py | 32 ++ astrbot/core/cron/manager.py | 12 + astrbot/core/persona_anchor.py | 190 ++++++++++++ .../method/agent_sub_stages/internal.py | 26 ++ astrbot/core/prompt_injection_guard.py | 292 ++++++++++++++++++ tests/unit/test_persona_anchor.py | 126 ++++++++ tests/unit/test_prompt_injection_guard.py | 145 +++++++++ 10 files changed, 984 insertions(+) create mode 100644 astrbot/core/persona_anchor.py create mode 100644 astrbot/core/prompt_injection_guard.py create mode 100644 tests/unit/test_persona_anchor.py create mode 100644 tests/unit/test_prompt_injection_guard.py diff --git a/astrbot/core/astr_agent_tool_exec.py b/astrbot/core/astr_agent_tool_exec.py index e42f665316..818da0bcb4 100644 --- a/astrbot/core/astr_agent_tool_exec.py +++ b/astrbot/core/astr_agent_tool_exec.py @@ -583,6 +583,18 @@ async def _wake_main_agent_for_background_result( safety_mode_strategy=persona_config.get( "safety_mode_strategy", "system_prompt" ), + prompt_injection_guard=persona_config.get("prompt_injection_guard", False), + prompt_injection_guard_strategy=persona_config.get( + "prompt_injection_guard_strategy", "warn" + ), + prompt_injection_guard_extra_patterns=persona_config.get( + "prompt_injection_guard_extra_patterns", [] + ), + persona_anchor=persona_config.get("persona_anchor", False), + persona_anchor_template=persona_config.get("persona_anchor_template", ""), + language_anchor=persona_config.get("language_anchor", False), + language_anchor_language=persona_config.get("language_anchor_language", ""), + language_anchor_template=persona_config.get("language_anchor_template", ""), computer_use_runtime=provider_settings.get("computer_use_runtime", "none"), sandbox_cfg=provider_settings.get("sandbox", {}), provider_settings=provider_settings, diff --git a/astrbot/core/astr_main_agent.py b/astrbot/core/astr_main_agent.py index bc13feef9b..15c6e5ae4d 100644 --- a/astrbot/core/astr_main_agent.py +++ b/astrbot/core/astr_main_agent.py @@ -23,6 +23,8 @@ from astrbot.core.astr_main_agent_resources import ( CHATUI_INLINE_GENUI_SYSTEM_PROMPT, CHATUI_SPECIAL_DEFAULT_PERSONA_PROMPT, + INJECTION_GUARD_BLOCK_MESSAGE, + INJECTION_GUARD_SYSTEM_PROMPT, LIVE_MODE_SYSTEM_PROMPT, LLM_SAFETY_MODE_SYSTEM_PROMPT, SANDBOX_MODE_PROMPT, @@ -33,12 +35,20 @@ from astrbot.core.conversation_mgr import Conversation from astrbot.core.db import BaseDatabase from astrbot.core.message.components import File, Image, Record, Reply, Video +from astrbot.core.persona_anchor import ( + build_language_rule, + build_persona_anchor, + build_persona_hardening, +) from astrbot.core.persona_error_reply import ( extract_persona_custom_error_message_from_persona, set_persona_custom_error_message_on_event, ) from astrbot.core.platform.astr_message_event import AstrMessageEvent from astrbot.core.platform.message_type import MessageType +from astrbot.core.prompt_injection_guard import ( + PromptInjectionGuard, +) from astrbot.core.provider import Provider from astrbot.core.provider.entities import ProviderRequest from astrbot.core.provider.register import llm_tools @@ -218,6 +228,22 @@ class MainAgentBuildConfig: """This will inject healthy and safe system prompt into the main agent, to prevent LLM output harmful information""" safety_mode_strategy: str = "system_prompt" + prompt_injection_guard: bool = False + """检测并处理用户输入中的提示词注入尝试。""" + prompt_injection_guard_strategy: str = "warn" + """block / sanitize / warn / log。""" + prompt_injection_guard_extra_patterns: list[str] = field(default_factory=list) + """额外的自定义正则。""" + persona_anchor: bool = False + """工具调用后重申人设，避免模型自称 AI 助手。""" + persona_anchor_template: str = "" + """自定义模板，需含 {persona}。""" + language_anchor: bool = False + """要求模型使用单一语言，避免中英混排。""" + language_anchor_language: str = "" + """语言代码（zh / en）或语言名（中文 / English）。""" + language_anchor_template: str = "" + """自定义模板，需含 {lang}。""" computer_use_runtime: str = "none" """The runtime for agent computer use: none, local, or sandbox.""" sandbox_cfg: dict = field(default_factory=dict) @@ -569,6 +595,11 @@ async def _ensure_persona_and_skills( ) if persona: + try: + event.set_extra("_persona_name", persona.get("name") or persona_id or "") + except Exception: # noqa: BLE001 -

sourcery-ai review findings 1. sanitize(): normalise + strip zero-width BEFORE applying rules, so an obfuscated payload cannot be "cleaned" into readable attack text. 2. Guard now also scans extra_user_content_parts, not just req.prompt, so quoted/plugin-supplied text cannot bypass the configured strategy. 3. Remove the unused wrap_tool_result() helper -- it was never wired into the tool-result path, so advertising it as isolation was misleading. 4. Extra pattern validation now skips non-str entries and catches TypeError as well as re.error, so one bad config value can't disable the guard. 5. Expose prompt_injection_guard_extra_patterns, persona_anchor_template and language_anchor_template in the WebUI schema (previously unconfigurable). --- .gitignore | 6 ++++++ astrbot/core/astr_main_agent.py | 16 ++++++++++++---- astrbot/core/config/default.py | 25 +++++++++++++++++++++++++ astrbot/core/persona_anchor.py | 14 -------------- astrbot/core/prompt_injection_guard.py | 4 +++- tests/unit/test_persona_anchor.py | 15 --------------- 6 files changed, 46 insertions(+), 34 deletions(-) diff --git a/.gitignore b/.gitignore index 8304f1e311..abfca37217 100644 --- a/.gitignore +++ b/.gitignore @@ -65,3 +65,9 @@ GenieData/ .worktrees/ dashboard/bun.lock + +_m.txt +_pr.md +_msg.txt +_s.json +_r*.json diff --git a/astrbot/core/astr_main_agent.py b/astrbot/core/astr_main_agent.py index 15c6e5ae4d..2016e9d520 100644 --- a/astrbot/core/astr_main_agent.py +++ b/astrbot/core/astr_main_agent.py @@ -1183,10 +1183,18 @@ def _apply_prompt_injection_guard( guard = PromptInjectionGuard( extra_patterns=config.prompt_injection_guard_extra_patterns, ) -

sanitize() now NFKC-normalises and strips zero-width characters before applying rules. Previously detection ran on the normalised text but sanitize() re-applied the rules to the raw text, so a payload detected in an obfuscated form was returned untouched: the sanitize strategy silently failed open on exactly the obfuscation it claims to cover. Detected base64 payloads are redacted too instead of being left in place. - _BASE64_BLOB no longer backtracks the '=' padding out of the match. A trailing \b ended the match before the padding, and the strict decoder then rejected the truncated string, which the except swallowed, so base64 detection never fired for any payload that needs padding (~2/3 of cases). Candidates are also retried with restored padding. - _apply_prompt_injection_guard no longer writes another content part's sanitized text back into req.prompt. When a quoted or plugin-injected part matched more rules than the user's own message, the user's message was replaced by that part's sanitized text. Every source is now sanitized in place and only req.prompt's own content can update req.prompt. - _apply_persona_anchor only injects the hardening line and the anchor when persona_anchor is enabled and a persona was actually resolved, so enabling language_anchor alone no longer leaks "stay in character" text into prompts that have no persona, as the two modules are meant to be independent. - pi_role_hijack no longer matches plain statements such as "接下来是重点" or "从现在起是新的版本了"; it requires an explicit role verb or a subject copula ("从现在起你就是一条龙", "接下来你要扮演一个医生"). - pi_ignore_instructions ignores first-person statements about the user's own memory ("我忘记之前的所有设定了"), while still matching imperatives such as "忽略以上所有指令". - Document detect_mixed_language as a standalone utility that the request path does not call, and drop the duplicated .gitignore entry.

copy: - INJECTION_GUARD_BLOCK_MESSAGE (shown to the end user when a message is blocked) and INJECTION_GUARD_SYSTEM_PROMPT (appended to the system prompt under the warn strategy) are now Chinese, matching the Chinese persona and language anchor prompts. - Comments and docstrings of the guard and anchor code are Chinese, matching the rest of this pull request. - The .gitignore comment is back to Chinese.

It also removes the flagged parts now, so the payload is actually stopped instead of being sent to the model anyway while the reply claims the message was not processed. - Encoding heuristics (`pi_zero_width`, `pi_base64_payload`) no longer drive the configured strategy on their own. A zero-width character copied from a web page or an unrelated base64-looking token is still logged, but leaves the request untouched, so `block` stops rejecting normally pasted text. - `sanitize` only rewrites a source that matched itself. Normalising a clean prompt (NFKC plus zero-width stripping) no longer rewrites the user's text just because some other part matched. Adds six regression tests: the block/parts interaction (prompt preserved, dirty part dropped), heuristic-only detections under `block` and `warn`, and the sanitize write-back.

The two migration tests assert the migrated structure against a hardcoded persona block, so they failed with the new keys missing. Extend both expectations to the new defaults. The failure was invisible until now because CI has never run on this branch (all five workflows are still `action_required`), so the suite is green again with 3565 tests. --- tests/unit/test_agent_runner_config.py | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/tests/unit/test_agent_runner_config.py b/tests/unit/test_agent_runner_config.py index 67b11e208e..1b231c7443 100644 --- a/tests/unit/test_agent_runner_config.py +++ b/tests/unit/test_agent_runner_config.py @@ -150,6 +150,14 @@ def test_local_legacy_fields_are_fully_migrated(): "persona_id": "developer", "safety_mode": False, "safety_mode_strategy": "system_prompt", + "prompt_injection_guard": False, + "prompt_injection_guard_strategy": "warn", + "prompt_injection_guard_extra_patterns": [], + "persona_anchor": False, + "persona_anchor_template": "", + "language_anchor": False, + "language_anchor_language": "", + "language_anchor_template": "", }, "compression": { "max_turns": 20, @@ -230,6 +238,14 @@ def test_local_migration_replaces_default_root_inserted_before_version_bump(): "persona_id": "developer", "safety_mode": False, "safety_mode_strategy": "system_prompt", + "prompt_injection_guard": False, + "prompt_injection_guard_strategy": "warn", + "prompt_injection_guard_extra_patterns": [], + "persona_anchor": False, + "persona_anchor_template": "", + "language_anchor": False, + "language_anchor_language": "", + "language_anchor_template": "", }, "compression": { "max_turns": 24, From 2d2e6a772fa135e1951f3348582541b902b25f0c Mon Sep 17 00:00:00 2001 From: PhiLia011 <232066573+PhiLia011@users.noreply.github.com> Date: Mon, 21 Sep 2026 11:58:40 +0800 Subject: [PATCH 10/10] docs(changelog): record the guard and anchor options in changelogs/unreleased.md MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit User-visible additions are announced in the pending-release changelog, next to the existing unreleased entries.

Larger originals are skipped before reading image bytes, with a model notice retaining their paths and suggesting the file-reading tool or a smaller upload; accepted inputs still produce images strictly below 512 KiB. - Local Agent input images are always prepared as JPEG/PNG files strictly below 512 KiB. Compliant local images are reused without copying. Transparent previews retain PNG alpha; animations become 3×3 montages. Original attachment paths remain available to tools, and event-owned previews are deleted after use without a shared conversion cache. - Configuration mapping: **Enable image compression** (`provider_settings.image_compress_enabled`) is replaced by always-on preparation; **JPEG quality** (`provider_settings.image_compress_options.quality`) is replaced by automatic size control; **Maximum edge length** is renamed to **Input image maximum edge length** (`provider_settings.image_compress_options.max_size`). User attachments in CUA sessions follow the same limits. +- Add an opt-in prompt injection guard to the main agent: 12 bilingual rules plus zero-width character and base64 payload detection, with `warn` / `block` / `sanitize` / `log` strategies and support for custom regex patterns. `block` rewrites only the source that actually matched and removes the flagged extra content parts, and encoding heuristics on their own never block or warn. Off by default. +- Add opt-in persona and language anchoring to the main agent: the persona is re-asserted on every request, so a tone that drifted after a tool call is pulled back on the next turn, and replies can be pinned to a single language with a proper-noun whitelist. Off by default. +- New configuration under `agent_runner.config.persona`: `prompt_injection_guard`, `prompt_injection_guard_strategy`, `prompt_injection_guard_extra_patterns`, `persona_anchor`, `persona_anchor_template`, `language_anchor`, `language_anchor_language` and `language_anchor_template`. They are registered in `AGENT_RUNNER_CONFIG_DEFAULTS` so a dashboard save keeps them, and are exposed in the persona settings schema.
