{"id":"CVE-2026-29612","aliases":["GHSA-w2cg-vxx6-5xjg"],"url":"https://o3.security/vulnerability/CVE-2026-29612","summary":"OpenClaw < 2026.2.14 - Denial of Service via Large Base64 Media File Decoding","details":"## Summary\n\nBase64-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.\n\n## Attack Scenario Notes\n\n- 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.\n- 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.\n\n## Affected Packages / Versions\n\n- openclaw (npm): <= 2026.2.13\n- clawdbot (npm): <= 2026.1.24-3\n\n## Fixed In\n\n- openclaw (npm): 2026.2.14 (planned)\n- clawdbot (npm): no patched release planned; migrate to openclaw\n\n## Fix Commit(s)\n\n- 31791233d60495725fa012745dde8d6ee69e9595\n\n## Credits\nThanks @vincentkoc for reporting.","published":"2026-03-05T22:00:10.538Z","modified":"2026-10-28T02:31:13.506008404Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.14"},{"ecosystem":"npm","name":"clawdbot","fixedVersion":null}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/31791233d60495725fa012745dde8d6ee69e9595","label":"openclaw/openclaw@3179123"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29612.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-w2cg-vxx6-5xjg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-29612"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-denial-of-service-via-large-base-media-file-decoding"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/31791233d60495725fa012745dde8d6ee69e9595"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/releases/tag/v2026.2.14"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:31:13.506008404Z"}}
