CVE-2026-60089 MervinPraison CVE debrief
CVE-2026-60089 is a path traversal vulnerability in PraisonAI, a pip package for AI agents. Versions before 1.6.78 are affected. The vulnerability allows an untrusted checked-out project to overwrite files outside the project root with the privileges of the user running PraisonAI. This is possible because PraisonAI automatically loads defaults from a project-local .praisonai/config.toml file and does not validate the defaults.output.output_file path. A repository-controlled config file can set output_file to an absolute or '..' traversal path. When the developer subsequently calls agent.start() without explicitly passing an output parameter, PraisonAI writes the agent response to that path, creating parent directories as needed.

Who should care
Developers and users of PraisonAI versions before 1.6.78 should be aware of this vulnerability and take steps to mitigate it. This includes updating to version 1.6.78 or later, validating output file paths, and ensuring that project-local config files are trusted.
Technical summary
The vulnerability exists in the PraisonAI package, specifically in the way it handles output file paths. When constructing an Agent, PraisonAI loads defaults from a project-local .praisonai/config.toml file without validating the defaults.output.output_file path. This allows an attacker to control the output file path, potentially leading to arbitrary file overwrite. A repository-controlled config file can set output_file to an absolute or '..' traversal path. When the developer subsequently calls agent.start() without explicitly passing an output parameter, PraisonAI writes the agent response to that path, creating parent directories as needed. Developers and users of PraisonAI versions before 1.6.78 should validate output file paths and ensure that project-local config files are trusted.
Defensive priority
High
Recommended defensive actions
- Update PraisonAI to version 1.6.78 or later
- Validate output file paths in project-local config files
- Ensure that project-local config files are trusted
- Monitor for suspicious activity related to PraisonAI
- Review compensating controls for exposed systems while remediation is scheduled and verified
- Check relevant monitoring, detection, and logs for exposed assets that need extra review
- Track exceptions, retest remediated assets, and close the item only after evidence is documented
