CVE-2026-54760 langroid CVE debrief

Who should care

Users of Langroid framework versions prior to 0.65.1 should apply patches to prevent SQL injection attacks. Affected operators and platforms should review their deployments and assign owners for follow-up. Vulnerability management and security teams should prioritize patching and monitor for suspicious SQL activity.

Technical summary

CVE-2026-54760 is a critical SQL injection vulnerability in the Langroid framework. The vulnerability arises from a bypassable regex blocklist in the SQLChatAgent, which allows attackers to execute PostgreSQL functions, including the previously blocked pg_read_file function. This issue was introduced due to the blocklist's inadequacy in handling function names separated from parentheses by quoted identifiers, inline comments, or schema qualifications. The vulnerability allows for arbitrary SQL execution and has a CVSS score of 9.3.

Defensive priority

High priority should be given to patching Langroid framework installations, as this vulnerability allows for arbitrary SQL execution. Defensive measures include reviewing compensating controls for exposed systems, checking relevant monitoring and detection logs, and tracking exceptions.

Recommended defensive actions

• Apply patches by upgrading to Langroid version 0.65.1 or later
• Review and update SQLChatAgent configurations to ensure the allowlist and blocklist are properly set
• Monitor for suspicious SQL activity
• Perform inventory checks for Langroid framework usage
• Implement compensating controls, such as Web Application Firewalls (WAFs), to detect and prevent SQL injection attacks
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
