Langroid is a framework for building large-language-model-powered applications. Prior to version 0.65.1, the "SQLChatAgent" SQL-injection mitigation, with default "allow_dangerous_operations=False", combines a raw-text regex blocklist ("_DANGEROUS_SQL_PATTERNS") with a "sqlglot" SELECT-only statement allowlist. The blocklist entries that target callable functions require the function name to be immediately followed by "\s*\(". PostgreSQL accepts the same call with the name separated from "(" by a quoted identifier, an inline comment, or schema qualification. These forms evade the regex, still parse as "SELECT", and execute the same PostgreSQL function. This restores the "pg_read_file" server-side file-read primitive that the prior CVE-2026-25879 / GHSA-pmch-g965-grmr fix was meant to block: the parent advisory fixed a missing "pg_read_file" blocklist entry, while this report shows that the added regex is bypassable. Version 0.65.1 fixes the issue.
