{"id":"PYSEC-2026-285","summary":"AstrBot is vulnerable to RCE with hard-coded JWT signing keys","details":"### Summary\nAstrBot uses a hard-coded JWT signing key, allowing attackers to execute arbitrary commands by installing a malicious plugin.\n\n### Details\n \nAstrBot uses a [hard-coded JWT signing key](https://github.com/AstrBotDevs/AstrBot/blob/v3.5.16/astrbot/core/__init__.py), which allows attackers to bypass the authentication mechanism. Once bypassed, the attacker can install a Python plugin that will be imported [here](https://github.com/AstrBotDevs/AstrBot/blob/master/astrbot/dashboard/routes/plugin.py), enabling arbitrary command execution on the target host.\n\n### Impact\n\nAll publicly accessible AstrBot instances are vulnerable.\n\nFor more information, please see: [CVE-2025-55449-AstrBot-RCE](https://github.com/Marven11/CVE-2025-55449-AstrBot-RCE)\n \n### Patch\n\nThis vulnerability was first reported on **2025-06-21** and was patched on the **same day** (2025-06-21).\n\nThe vulnerability was publicly disclosed on **2025-11-14**. Prior to public disclosure, monitoring from AstrBot Cloud indicated that fewer than 2% of deployed instances were still running the affected version. Therefore, this disclosure is not expected to have a significant impact on existing active instances.","aliases":["CVE-2025-55449","GHSA-4m32-cjv7-f425"],"modified":"2026-07-01T20:22:49.477669Z","published":"2026-06-29T11:50:36.550940Z","references":[{"type":"WEB","url":"https://github.com/AstrBotDevs/AstrBot/security/advisories/GHSA-4m32-cjv7-f425"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-55449"},{"type":"WEB","url":"https://github.com/AstrBotDevs/AstrBot/commit/d03e9fb90a0921a1bd10cf480bdacc9aaa246472"},{"type":"PACKAGE","url":"https://github.com/AstrBotDevs/AstrBot"},{"type":"WEB","url":"https://github.com/AstrBotDevs/AstrBot/releases/tag/v3.5.18"},{"type":"WEB","url":"https://github.com/Marven11/CVE-2025-55449-AstrBot-RCE"},{"type":"PACKAGE","url":"https://pypi.org/project/astrbot"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-4m32-cjv7-f425"}],"affected":[{"package":{"name":"astrbot","ecosystem":"PyPI","purl":"pkg:pypi/astrbot"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.18"}]}],"versions":["3.4.39","3.5.10","3.5.11","3.5.12","3.5.13","3.5.14","3.5.15","3.5.17","3.5.6","3.5.7","3.5.8","3.5.9"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/astrbot/PYSEC-2026-285.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
