Title
OpenClaw < 2026.2.14 - Denial of Service via Large Base64 Media File Decoding
Summary
OpenClaw versions prior to 2026.2.14 decode base64-backed media inputs into buffers before enforcing decoded-size budget limits, allowing attackers to trigger large memory allocations. Remote attackers can supply oversized base64 payloads to cause memory pressure and denial of service.
