CVE-2026-56074 PraisonAI CVE debrief

CVE-2026-56074 is a medium-severity vulnerability in PraisonAI that allows attackers to bypass tool approval prompts by exploiting coarse-grained caching of tool approval decisions. The vulnerability exists because PraisonAI caches tool approval decisions by tool name only, not by invocation arguments. This means that an attacker can obtain initial approval for a benign command and then silently exfiltrate API keys and credentials via subsequent shell commands without user consent. Affected deployments should be reviewed for exposure.

Who should care

Users of PraisonAI versions before 1.5.128 should be aware of this vulnerability and take steps to mitigate it. This includes ensuring that the latest version of PraisonAI is installed and that appropriate security measures are in place to detect and prevent exploitation. Operators, security teams, and platform administrators are impacted.

Technical summary

The vulnerability is caused by PraisonAI's coarse-grained caching of tool approval decisions. When a user approves a tool for execution, PraisonAI caches the approval decision based on the tool name only, without considering the invocation arguments. This allows an attacker to bypass the approval prompt for subsequent executions of the tool with different arguments. The vulnerability has a CVSS score of 6.8 and a severity rating of MEDIUM. Defenders should focus on upgrading to version 1.5.128 or later.

Defensive priority

High

Recommended defensive actions

  • Upgrade to PraisonAI version 1.5.128 or later
  • Implement additional security measures to detect and prevent exploitation
  • Monitor for suspicious activity and review tool approval decisions
  • 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
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
