{"id":"GHSA-pg8g-f2hf-x82m","summary":"Duplicate Advisory: OpenClaw: `fetchWithSsrFGuard` replays unsafe request bodies across cross-origin redirects","details":"### Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-qx8j-g322-qj6m. This link is maintained to preserve external references.\n\n### Original Description\nOpenClaw before 2026.3.31 (patched in 2026.4.8) contains a request body replay vulnerability in fetchWithSsrFGuard that allows unsafe request bodies to be resent across cross-origin redirects. Attackers can exploit this by triggering redirects to exfiltrate sensitive request data or headers to unintended origins.","modified":"2026-04-10T20:35:04.952074Z","published":"2026-04-09T00:31:59Z","withdrawn":"2026-04-10T20:24:54Z","database_specific":{"cwe_ids":["CWE-601"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-04-10T20:24:54Z","nvd_published_at":"2026-04-08T22:16:24Z"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-qx8j-g322-qj6m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40037"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/d7c3210cd6f5fdfdc1beff4c9541673e814354d5"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-unsafe-request-body-replay-via-fetchwithssrfguard-cross-origin-redirects"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.4.8"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-pg8g-f2hf-x82m/GHSA-pg8g-f2hf-x82m.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
