CVE-2026-29612 Details
Description
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.
A denial-of-service vulnerability has been identified in OpenClaw versions prior to 2026.2.14. The issue arises because the application decodes base64-encoded media inputs into buffers without first enforcing size limits on the decoded data. This flaw allows remote attackers to send oversized base64 payloads, leading to large memory allocations that create memory pressure and cause denial-of-service conditions.
Users can upgrade to OpenClaw version 2026.2.14 or later to address this vulnerability.
