PT-2026-31457

Name of the Vulnerable Software and Affected Versions PraisonAI versions prior to 4.5.115 Description PraisonAI's AgentService.loadAgentFromFile method uses the js-yaml library to parse YAML files without disabling dangerous tags like !!js/function and !!js/undefined. This allows an attacker to...

PT-2026-31717

Name of the Vulnerable Software and Affected Versions: PraisonAI versions prior to 4.5.121 Description: PraisonAI's workflow system and command execution tools are susceptible to command injection attacks because they pass user-controlled input directly to subprocess.run with shell=True. This...

CVE-2026-39889: Exposure of Sensitive Information to an Unauthorized Actor

PraisonAI is a multi-agent teams system. Prior to 4.5.115, the A2U Agent-to-User event stream server in PraisonAI exposes all agent activity without authentication. The createa2uroutes function registers the following endpoints with NO authentication checks: /a2u/info, /a2u/subscribe,...

CVE-2026-39890: Deserialization of Untrusted Data

PraisonAI is a multi-agent teams system. Prior to 4.5.115, the AgentService.loadAgentFromFile method uses the js-yaml library to parse YAML files without disabling dangerous tags such as !!js/function and !!js/undefined. This allows an attacker to craft a malicious YAML file that, when parsed,...

CVE-2026-39307

PraisonAI is a multi-agent teams system. Prior to 1.5.113, The PraisonAI templates installation feature is vulnerable to a "Zip Slip" Arbitrary File Write attack. When downloading and extracting template archives from external sources e.g., GitHub, the application uses Python's zipfile.extractall...

CVE-2026-39308

PraisonAI is a multi-agent teams system. Prior to 1.5.113, PraisonAI's recipe registry publish endpoint writes uploaded recipe bundles to a filesystem path derived from the bundle's internal manifest.json before it verifies that the manifest name and version match the HTTP route. A malicious...

CVE-2026-35615

PraisonAI is a multi-agent teams system. Prior to 1.5.113, validatepath calls os.path.normpath first, which collapses .. sequences, then checks for '..' in normalized. Since .. is already collapsed, the check always passes. This makes the check completely useless and allows trivial path traversal...
