CVE-2026-39306: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in MervinPraison PraisonAI
PraisonAI is a multi-agent teams system. Prior to 1.5.113, PraisonAI's recipe registry pull flow extracts attacker-controlled .praison tar archives with tar.extractall() and does not validate archive member paths before extraction. A malicious publisher can upload a recipe bundle that contains ../ traversal entries and any user who later pulls that recipe will write files outside the output directory they selected. This is a path traversal / arbitrary file write vulnerability on the client side of the recipe registry workflow. It affects both the local registry pull path and the HTTP registry pull path. The checksum verification does not prevent exploitation because the malicious traversal payload is part of the signed bundle itself. This vulnerability is fixed in 1.5.113.
AI Analysis
Technical Summary
PraisonAI, a multi-agent teams system by MervinPraison, had a path traversal vulnerability (CWE-22) in its recipe registry pull flow before version 1.5.113. The system uses tar.extractall() to extract .praison tar archives without validating the paths of archive members. An attacker can craft a malicious recipe bundle containing ../ path traversal entries, causing files to be written outside the intended directory on the client side during extraction. This vulnerability affects both local and HTTP pull methods. Checksum verification does not mitigate the risk because the malicious traversal payload is included in the signed archive. The vulnerability is addressed in version 1.5.113.
Potential Impact
An attacker who publishes a malicious recipe bundle can cause arbitrary files to be written outside the designated output directory on the client system when users pull the recipe. This can lead to integrity violations and potential denial of service on the client side. The vulnerability has a CVSS 3.1 score of 7.3 (high severity), indicating a significant impact on integrity and availability with network attack vector and low attack complexity requiring user interaction and privileges.
Mitigation Recommendations
This vulnerability is fixed in PraisonAI version 1.5.113. Users and administrators should upgrade to version 1.5.113 or later to remediate this issue. Since no official patch link or advisory is provided, confirm the upgrade from the vendor's official channels. Until upgraded, avoid pulling recipe bundles from untrusted sources to reduce risk.
