CVE-2026-57128: PraisonAI: Unauthenticated Event Injection via SSE `/publish` Endpoint

Noroxi assessment

Priority: Monitor (action score 17/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.25% (FIRST EPSS).
  • Someone on the same network segment can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: praisonaiagents (PyPI) 1.6.59.

Low priority for now. Upgrade to praisonaiagents (PyPI) 1.6.59 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.58, the SSE server in src/praisonai-agents/praisonaiagents/server/server.py does not consult ServerConfig.auth_token before handling /publish, /events, or /info requests. A network client that can reach the server can broadcast arbitrary events to connected clients and obtain server configuration and client-count information. This issue is fixed in praisonaiagents 1.6.58.
