CVE-2023-50253Public exploitNetwork attack vector

Cross-pod log disclosure via unchecked pod name

Published Jan 3, 2024 · Updated Jun 9, 2025

Information disclosure in Labring LAF 1.0.0-beta.13 and earlier allows remote authenticated users to read other pods' logs. The log API accepts a caller-controlled pod name after checking only JWT and application guards, without verifying that the requested pod belongs to the caller's application. A valid token and application ID within the shared namespace expose sensitive data written by other workloads to their container logs.
