CVE-2026-35633 Details
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.
A vulnerability allowing unbounded memory allocation has been identified in OpenClaw versions prior to 2026.3.22. This issue arises in the handling of remote media HTTP error responses, where the application fails to impose a limit on memory allocation. Attackers can exploit this by sending crafted HTTP error responses with large bodies to remote media endpoints, causing excessive memory consumption before the application can process the error. This vulnerability has been patched in version 2026.3.22 and is also present in the latest release, 2026.3.23-2.
Users can upgrade to OpenClaw version 2026.3.22 or later to address this vulnerability.
