CVE-2026-56834 MervinPraison CVE debrief

Who should care

Defenders responsible for PraisonAI deployments, particularly those using versions between 3.8.1 and 4.6.59, should assess exposure and prioritize upgrading to version 4.6.59 or later.

Why it matters

CVE-2026-56834 allows unauthorized file reads in PraisonAI, potentially exposing sensitive information. Defenders should prioritize upgrading to version 4.6.59 or later and review PraisonAI configurations.

• Potential unauthorized reads of sensitive files
• Possible exposure of project .env files, cloud credentials, SSH keys, or source files
• Need to verify PraisonAI configurations and artifact storage settings
• Requirement to monitor PraisonAI logs for suspicious activity

Technical summary

The Dynamic Context Discovery feature in PraisonAI exposes artifact helper tools through ctx.get_tools(). These tools do not enforce that the supplied artifact_path is an artifact created by the configured store or lives under the configured artifact base directory. This allows any prompt/user/tool-caller that can influence those tool arguments to read files readable by the PraisonAI process, potentially exposing sensitive information such as project .env files, cloud credentials, SSH keys, or source files. The issue has been patched in version 4.6.59.

Defensive priority

Defenders should prioritize upgrading to version 4.6.59 or later and review PraisonAI configurations.

Recommended defensive actions

• Upgrade to PraisonAI version 4.6.59 or later
• Review PraisonAI configurations and artifact storage settings
• Monitor PraisonAI logs for suspicious activity
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• 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
