{"id":"GHSA-9gvx-vj57-vqqx","summary":"Duplicate Advisory: OpenClaw: Gateway Canvas local-direct requests bypass Canvas HTTP and WebSocket authentication","details":"### Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-6mqc-jqh6-x8fc. This link is maintained to preserve external references.\n\n### Original Description\nOpenClaw before 2026.3.23 contains an authentication bypass vulnerability in the Canvas gateway where authorizeCanvasRequest() unconditionally allows local-direct requests without validating bearer tokens or canvas capabilities. Attackers can send unauthenticated loopback HTTP and WebSocket requests to Canvas routes to bypass authentication and gain unauthorized access.","modified":"2026-04-10T20:33:51.877029Z","published":"2026-04-10T00:30:30Z","withdrawn":"2026-04-10T20:19:41Z","database_specific":{"cwe_ids":["CWE-288"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-04-10T20:19:41Z","nvd_published_at":"2026-04-09T22:16:32Z"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-6mqc-jqh6-x8fc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35634"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/630f1479c44f78484dfa21bb407cbe6f171dac87"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/d5dc6b6573ae489bc7e5651090f4767b93537c9e"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-authentication-bypass-via-local-direct-requests-in-canvas-gateway"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.3.23"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-9gvx-vj57-vqqx/GHSA-9gvx-vj57-vqqx.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/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"}]}
