CVE-2026-54760

CVE-2026-54760: Langroid’s SQLChatAgent dangerous-function blocklist can be bypassed. Prior to version 0.65.1, the mitigation combines a raw-text regex (_DANGEROUS_SQL_PATTERNS) with a sqlglot-based SELECT-only allowlist. Attackers can defeat the regex using PostgreSQL forms such as quoted identi...

CVE-2026-50181

CVE-2026-50181 affects Langroid up to version 0.63.0, where ReadFileTool and WriteFileTool incorrectly trust curr_dir as a boundary. The tools change the process working directory to curr_dir and then operate on user-supplied file_path without resolving that the final path remains inside curr_dir...

CVE-2026-50181 Langroid: Path traversal in the file tools allows read/write outside configured current directory

Langroid is a framework for building large-language-model-powered applications. Prior to version 0.64.0, Langroid's ReadFileTool and WriteFileTool appear to treat currdir as the intended working-directory boundary for file operations. However, the tools only change the process working directory t...

CVE-2026-50180

Summary: CVE-2026-50180 in Langroid’s SQLChatAgent allows arbitrary PostgreSQL file reads due to an incomplete DANGEROUS_SQL_PATTERNS blocklist. The blocklist misses several pg_read * and related functions (e.g., pg_read_file, pg_stat_file, pg_ls_logdir, pg_ls_waldir, pg_current_logfile) and does...

CVE-2026-50180 Langroid: SQLChatAgent _validate_query blocklist misses pg_read_file family enabling arbitrary file read

Langroid is a framework for building large-language-model-powered applications. Prior to version 0.64.0, SQLChatAgent in langroid ships a validatequery defense-in-depth layer whose DANGEROUSSQLPATTERNS regex blocklist enumerates dangerous SQL primitives by specific function name. The list misses...

CVE-2026-55615

Langroid CVE-2026-55615 affects the Neo4jChatAgent path, where LLM-generated Cypher queries are sent unvalidated to the Neo4j driver prior to version 0.65.5.
