要点
- CVE-2026-29612 は openclaw (openclaw), clawdbot, openclaw に影響する深刻度「高」 (CVSS 7.5) の脆弱性です。
- 今後30日間に悪用される確率（EPSS）：0.31%（全脆弱性の 24.1% より高い）。
- 対処：2026.2.14 以降に更新してください。
概要
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)

Thanks @vincentkoc for reporting.
NVD の説明
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.
