CVE-2026-57131: praisonai: Jobs API exposes agent-execution endpoints with no authentication

What it is

PraisonAI is a multi-agent teams system. Prior to 4.6.58, praisonai.jobs.server.create_app mounts praisonai.jobs.router.create_router under /api/v1/runs without authentication or per-job authorization. Network clients can submit attacker-controlled prompts and agent configuration, list and read jobs, stream results, and cancel or delete other jobs, exposing service credentials and connected tool capabilities to unauthorized agent execution. This vulnerability is fixed in 4.6.58.

Description quoted from the CVE record (assigned by GitHub_M, published 2026-09-14).

Weakness: CWE-94: Improper Control of Generation of Code (‘Code Injection’); CWE-306: Missing Authentication for Critical Function; CWE-862: Missing Authorization

PraisonAI - Missing Authentication

PraisonAI prior to version 4.6.58 mounts the jobs API router (praisonai.jobs.router) under `/api/v1/runs` via praisonai.jobs.server.create_app without any authentication or per-job authorization. Unauthenticated network clients can submit attacker-controlled prompts and agent configurations, list and read jobs, stream results, and cancel or delete other jobs. Sending an unauthenticated POST to `/api/v1/runs` queues a new agent run and returns HTTP 202 with a `job_id`, a queued status and a poll URL, proving the endpoint executes privileged agent work without authentication.

Name and description quoted from the template, written by VEDAS.

The template sends 1 request (POST /api/v1/runs); it decides using status, word matchers. Severity in the template: critical. Marked as not yet verified against a live vulnerable target.
