Path Traversal in langroid (CVE-2026-54760)

Summary

Path traversal in langroid (CVE-2026-54760). Risk of unauthorized operations or information disclosure. Exploitable via _validate_query. Mitigation: upgrade to 0.65.1 or later.

Original description

The description as published by the source.

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.

❓ What is the problem

Path traversal (CWE-22) exists in langroid. Attackers reach the vulnerable code path via _validate_query.

📍 Affected scope

Check the vendor advisory for the affected versions of langroid. Attack surface: _validate_query / SQLChatAgent / _DANGEROUS_SQL_PATTERNS / sqlglot.

🔥 Severity

Severity: ?. Risk of unauthorized operations or information disclosure.

🔧 How to fix

Update to 0.65.1.

🛡️ Workaround

Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.

🔍 Detection

Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r 'langroid' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify
    grep -r 'langroid' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で langroid を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Apply patch patch
    Upgrade langroid to 0.65.1

    ステージング環境で 0.65.1 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスを含めること。

  3. 3
    Post-deployment verification verify
    Confirm patched version is live in production

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
