CVE-2026-50180 langroid CVE debrief

The Langroid framework, used for building large-language-model-powered applications, has a SQL injection vulnerability. An attacker can exploit this vulnerability to read arbitrary files from the PostgreSQL host through ordinary SELECT queries, even with the agent's strict default configuration. This vulnerability affects Langroid framework users, especially those using SQLChatAgent. The vulnerability allows attackers to bypass the defense-in-depth layer and access sensitive files.

Who should care

Users of Langroid framework, especially those using SQLChatAgent, should be aware of this vulnerability and take necessary actions to protect their applications. Affected operators and platforms should review and update their configurations to prevent exploitation.

Technical summary

The SQLChatAgent in Langroid has a defense-in-depth layer that blocks certain SQL patterns. However, it was found that this layer misses some canonical PostgreSQL filesystem-disclosure functions, such as pg_read_file(), pg_stat_file(), pg_ls_logdir(), pg_ls_waldir(), and pg_current_logfile(). Additionally, SQL Server OPENDATASOURCE and SQLite ATTACH '<file>' AS x are not blocked. An attacker can exploit this vulnerability to read arbitrary files from the PostgreSQL host through ordinary SELECT queries.

Defensive priority

High

Recommended defensive actions

  • Update Langroid to version 0.64.0 or later
  • Restrict SQL queries to only necessary and safe operations
  • Monitor and audit SQL queries for suspicious activity
  • Implement additional security measures, such as input validation and sanitization
  • 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

Evidence notes
