# Patch Next advisory brief: CVE-2026-47398

Advisory: PraisonAI: Arbitrary code execution via unguarded `spec.loader.exec_module` in `agents_generator.py` - sibling of CVE-2026-44334
IDs: CVE-2026-47398, GHSA-78r8-wwqv-r299
Record: https://patchnext.com/advisories/cve-2026-47398 (revision 2, source checked 26 Oct 2026, 13:41 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: praisonai 4.6.40. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI praisonai: affected <= 4.6.39; fixed in 4.6.40

## 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.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-78r8-wwqv-r299 (OSV record GHSA-78r8-wwqv-r299 lists affected ranges: PyPI praisonai >=0 <4.6.40 (fixed))
- Verified: https://github.com/advisories/GHSA-78r8-wwqv-r299 (GitHub-reviewed advisory GHSA-78r8-wwqv-r299 lists affected ranges: PyPI praisonai >=0 <=4.6.39)
