CVE-2026-58449

Full vulnerability record from the local CVENow database.

Description

txtai through 9.10.0, fixed in commit 11b32da, exposes an API /reindex endpoint whose function body parameter is resolved through txtai.util.Resolver, which performs __import__ and getattr on the caller-supplied dotted path with no allowlist. When the API is exposed with no TOKEN configured (authentication is opt-in, so all endpoints are unauthenticated) and the index is configured writable, a remote attacker can set function to an arbitrary callable such as subprocess.getoutput, achieving remote code execution as the server process during reindexing. Exploitation requires those deployment conditions (API exposed, no TOKEN, writable index); it is not the default configuration. The fix gates the endpoint behind a new reindex configuration flag.

      "value": "txtai hasta la versión 9.10.0, corregido en el commit 11b32da, expone un endpoint de la API /reindex cuyo parámetro ’function body’ se resuelve a través de txtai.util.Resolver, que realiza __import__ y getattr en la ruta punteada proporcionada por el llamador sin una lista de permitidos. Cuando la API se expone sin ningún TOKEN configurado (la autenticación es opcional, por lo que todos los endpoints no están autenticados) y el índice está configurado como escribible, un atacante remoto puede establecer ’function’ a un objeto invocable arbitrario como subprocess.getoutput, logrando ejecución remota de código como el proceso del servidor durante la reindexación. La explotación requiere esas condiciones de despliegue (API expuesta, sin TOKEN, índice escribible); no es la configuración predeterminada. La corrección protege el endpoint detrás de un nuevo indicador de configuración de reindexación."
