CVE-2026-10700Network attack vectorHinoki check available

Cross-tenant file disclosure via missing access checks

Published Jul 30, 2026 · Updated Jul 30, 2026

Broken access control in IBM Langflow OSS 1.0.0 through 1.8.4 allows remote attackers to retrieve other users' flow files. The images route accepts flow and file identifiers without authentication, while the download route authenticates callers but does not verify ownership of the requested flow. Knowledge of valid identifiers is required; image retrieval needs no account, while other file retrieval requires any authenticated account and exposes private-flow data in multi-user deployments.
