PraisonAI AgentTeam.launch exposes unauthenticated remote agent listing and invocation endpoints

CVE-2026-57118GHSA-x8cv-xmq7-p8xp

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (praisonaiagents 1.6.59), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

PraisonAI AgentTeam.launch() exposes unauthenticated remote agent invocation endpoints Summary PraisonAI's documented Python AgentTeam.launch() / Agents.launch() HTTP server starts externally reachable agent invocation endpoints without any authentication enforcement. The current implementation registers GET /{path}/list, POST /{path}, and POST /{path}/{agentid} routes. The POST routes directly call agent.chat(...). Requests with no Authorization header are accepted, and requests with an obviously wrong bearer token are also accepted. The default Python API bind host for Agents.launch() is 0.0.0.0, and official documentation shows host="0.0.0.0" for remote access. This is a sibling/incomplete-fix variant of PraisonAI's prior unauthenticated API server and call server advisory family. Nearby server surfaces were hardened to require tokens, fail closed, or bind locally by default, but the AgentTeam.launch() FastAPI path still exposes unauthenticated agent execution on current upstream…

# Patch Next advisory brief: CVE-2026-57118

Advisory: PraisonAI AgentTeam.launch exposes unauthenticated remote agent listing and invocation endpoints
IDs: CVE-2026-57118, GHSA-x8cv-xmq7-p8xp
Record: https://patchnext.com/advisories/cve-2026-57118 (revision 3, source checked 26 Oct 2026, 13:49 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: praisonaiagents 1.6.59. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI praisonaiagents: affected < 1.6.59; fixed in 1.6.59

## Suggested inspection (read-only)
- `python -m pip show praisonaiagents`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on praisonaiagents.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
