Summary Duplicate Advisory: OpenClaw: Remote media error responses could trigger unbounded memory allocation before failure ### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-4qwc-c7g9-4xcw. This link is maintained to preserve external references. ### Original Description OpenClaw before 2026.3.22 contains an unbounded memory allocation vulnerability in remote media HTTP error handling that allows attackers to trigger excessive memory consumption. Attackers can send crafted HTTP error responses with large bodies to remote media endpoints, causing the application to allocate unbounded memory before failure handling occurs.
