• CVE-2026-34952: 0.45% estimated exploitation activity in the next 30 days; percentile 39.32 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary The PraisonAI Gateway server accepts WebSocket connections at /ws and serves agent topology at /info with no authentication. Any network client can connect, enumerate registered agents, and send arbitrary messages to agents and their tool sets. Details gateway/server.py:242 (source) - gateway/server.py:250 (sink) PoC Impact Any unauthenticated attacker with network access can connect to the WebSocket gateway, enumerate all registered agents via /info, and send arbitrary messages to agents including tool execution, file reads, and API calls. GatewayConfig has an authtoken field that is never enforced in the handler. Suggested Fix

# Patch Next advisory brief: CVE-2026-34952

Advisory: PraisonAI Has Missing Authentication in WebSocket Gateway
IDs: CVE-2026-34952, GHSA-cfh6-vr3j-qc3g
Record: https://patchnext.com/advisories/cve-2026-34952 (revision 3, source checked 26 Oct 2026, 13:40 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: praisonai 4.5.97. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI praisonai: affected <= 4.5.96; fixed in 4.5.97

## Suggested inspection (read-only)
- `python -m pip show praisonai`: 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 praisonai.
- 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.
