CVE-2026-7658 (GCVE-0-2026-7658)

Vulnerability from cvelistv5 – Published: 2026-08-05 18:20 – Updated: 2026-08-05 19:42

Title

Langflow OSS is affected by arbitrary code execution in custom component validation and trusted code enforcement

Summary

IBM Langflow OSS 1.0.0 through 1.10.3 does not properly validate the username field, allowing attackers to inject path traversal sequences and bypass containment checks. This enables multiple severe impacts, including arbitrary directory deletion, cross-tenant data destruction, and JWT signing key deletion leading to session invalidation.

Severity

6.5 (Medium)
