{"id":"CVE-2026-28394","details":"OpenClaw versions prior to 2026.2.15 contain a denial of service vulnerability in the web_fetch tool that allows attackers to crash the Gateway process through memory exhaustion by parsing oversized or deeply nested HTML responses. Remote attackers can social-engineer users into fetching malicious URLs with pathological HTML structures to exhaust server memory and cause service unavailability.","aliases":["GHSA-p536-vvpp-9mc8"],"modified":"2026-03-14T15:06:14.863003Z","published":"2026-03-05T22:16:15.973Z","references":[{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-p536-vvpp-9mc8"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-denial-of-service-via-unbounded-response-parsing-in-web-fetch-tool"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/166cf6a3e04c7df42bea70a7ad5ce2b9df46d147"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openclaw/openclaw","events":[{"introduced":"0"},{"fixed":"ea487f05c1763f170381b6fcff73b0fea0fd12d5"},{"fixed":"166cf6a3e04c7df42bea70a7ad5ce2b9df46d147"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"2026.2.15"}]}}],"versions":["v0.1.0","v0.1.1","v0.1.2","v0.1.3","v1.0.4","v1.1.0","v1.2.0","v1.2.1","v1.2.2","v1.3.0","v2.0.0-beta1","v2.0.0-beta2","v2.0.0-beta3","v2.0.0-beta4","v2.0.0-beta5","v2026.1.10","v2026.1.11","v2026.1.11-1","v2026.1.11-2","v2026.1.11-3","v2026.1.12","v2026.1.12-2","v2026.1.13","v2026.1.14-1","v2026.1.15","v2026.1.16-2","v2026.1.20","v2026.1.21","v2026.1.22","v2026.1.23","v2026.1.24","v2026.1.24-1","v2026.1.29","v2026.1.30","v2026.1.5","v2026.1.5-1","v2026.1.5-2","v2026.1.5-3","v2026.1.8","v2026.1.9","v2026.2.1","v2026.2.12","v2026.2.13","v2026.2.14","v2026.2.2","v2026.2.3","v2026.2.6","v2026.2.6-1","v2026.2.6-2","v2026.2.6-3","v2026.2.9"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-28394.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
