CVE-2026-29612
|
| Summary | OpenClaw: denial of service through large base64 media files allocating large buffers before limit checks ## Summary Base64-backed media inputs could be decoded into Buffers before enforcing decoded-size budgets. An attacker supplying oversized base64 payloads can force large allocations, causing memory pressure and denial of service. ## Attack Scenario Notes - Recommended deployments bind the gateway to loopback by default and require gateway auth for HTTP endpoints. In that configuration, this is best modeled as a local/authorized DoS. - If an operator exposes the gateway to untrusted networks (or disables/weakens auth and rate limits), treat this as a higher-severity network DoS risk. ## Affected Packages / Versions - openclaw (npm): <= 2026.2.13 - clawdbot (npm): <= 2026.1.24-3 ## Fixed In - openclaw (npm): 2026.2.14 (planned) - clawdbot (npm): no patched release planned; migrate to openclaw ## Fix Commit(s) - 31791233d60495725fa012745dde8d6ee69e9595 ## Credits Thanks @vincentkoc for reporting. |
