{"id":"GHSA-35vf-vw9f-q3cr","summary":"Duplicate Advisory: OpenClaw: MCP loopback owner context is derived from server-issued bearer tokens","details":"### Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-r6xh-pqhr-v4xh. This link is maintained to preserve external references.\n\n### Original Description\nOpenClaw before 2026.4.22 derives loopback MCP owner context from spoofable server-issued bearer tokens in request headers. Non-owner loopback clients can present themselves as owner to bypass owner-gated operations by manipulating the sender-owner header metadata.","modified":"2026-05-11T16:37:28.581500Z","published":"2026-05-06T21:31:42Z","withdrawn":"2026-05-11T16:12:46Z","database_specific":{"nvd_published_at":"2026-05-06T20:16:35Z","cwe_ids":["CWE-290"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-05-11T16:12:46Z"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-r6xh-pqhr-v4xh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44118"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/3cb1a56bfc9579a0f2336f9cfa12a8a744332a19"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-owner-context-spoofing-via-bearer-token-header"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.4.22"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-35vf-vw9f-q3cr/GHSA-35vf-vw9f-q3cr.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/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"}]}
