CVE-2024-4151Public exploitNetwork attack vector

Cross-project prompt access via unchecked template identifiers

Published May 20, 2024 · Updated Jan 31, 2025

Improper access control in Lunary before 1.2.25 allows remote authenticated users to read or alter prompts in other projects. The GET and PATCH handlers for template versions accept a user-controlled template identifier without verifying that the referenced prompt belongs to the caller's project. Any account with access to one project can cross project boundaries, exposing prompt content or changing stored prompt data.
