CVE-2026-17529Public exploitNetwork attack vector

Authenticated tool access via late allowlist bypass

Published Jul 27, 2026 · Updated Jul 27, 2026

Incorrect authorization in AstrBotDevs AstrBot 4.25.0 through 4.25.5 allows remote authenticated users to invoke persona-disabled tools. The main-agent builder applies the persona allowlist before later helpers append web-search, cron, and proactive-messaging tools to req.func_tool without rechecking it. Exploitation requires an authenticated operator, a tool-restricted persona, and an enabled late-injected tool, and permits only the actions available to that exposed tool.
