Path Traversal in PraisonAI (CVE-2026-44340)
Summary
Path traversal in PraisonAI (CVE-2026-44340). Data can be tampered with by attackers. Exploitable via _safe_extractall. Mitigation: upgrade to 4.6.37 or later.
Original description
The description as published by the source.
Summary
The _safe_extractall helper that all recipe pull, recipe publish, and recipe unpack flows route through validates each archive member's name for absolute paths, .. segments, and resolved-path escape — but does not validate member.linkname, does not reject symlink/hardlink members, and calls tar.extractall(dest_dir) without filter="data". A bundle that contains a symlink with a name
inside dest_dir but a linkname pointing outside it, followed by a regular file whose path traverses through the just-created symlink, escapes dest_dir and lets the attacker write arbitrary content to an attacker-chosen location on the victim's filesystem.
Affected paths
Every code path that calls _safe_extractall is exposed:
| Caller | File:line |
|---|---|
praisonai recipe unpack |
src/praisonai/praisonai/cli/features/recipe.py:1175 (introduced as the fix for GHSA-99g3-w8gr-x37c) |

| Registry archive validation (publish) | src/praisonai/praisonai/recipe/registry.py:808 |
Root cause

CVE-2026-44340 (PraisonAI) — CWE-22 / CVSS v3 7.5
Attack vector: remote (network-reachable) / unauthenticated / no user interaction
Attack surface: _safe_extractall / name / member.linkname / dest_dir
Patched: 4.6.37 — apply immediately
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
Refs: see the GHSA / vendor advisory / patched release linked on this page.
Path traversal (CWE-22) exists in PraisonAI. Attackers reach the vulnerable code path via _safe_extractall without authentication.
Check the vendor advisory for the affected versions of PraisonAI. Attack surface: _safe_extractall / name / member.linkname / dest_dir.
Severity: High (CVSS 7.5/10). Data can be tampered with by attackers.
Update to 4.6.37.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r 'PraisonAI' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.
