{"id":"CVE-2026-26329","state":"PUBLISHED","title":"OpenClaw has a path traversal in browser upload allows local file read","description":"OpenClaw is a personal AI assistant. Prior to version 2026.2.14, authenticated attackers can read arbitrary files from the Gateway host by supplying absolute paths or path traversal sequences to the browser tool's `upload` action. The server passed these paths to Playwright's `setInputFiles()` APIs without restricting them to a safe root. An attacker must reach the Gateway HTTP surface (or otherwise invoke the same browser control hook endpoints); present valid Gateway auth (bearer token / password), as required by the Gateway configuration (In common default setups, the Gateway binds to loopback and the onboarding wizard generates a gateway token even for loopback); and have the `browser` tool permitted by tool policy for the target session/context (and have browser support enabled). If an operator exposes the Gateway beyond loopback (LAN/tailnet/custom bind, reverse proxy, tunnels, etc.), the impact increases accordingly. Starting in version 2026.2.14, the upload paths are now confined to OpenClaw's temp uploads root (`DEFAULT_UPLOAD_DIR`) and traversal/escape paths are rejected.","publishedAt":"2026-02-19T23:06:37.962Z","updatedAt":"2026-02-20T15:38:37.988Z","severity":{"score":7.1,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["openclaw openclaw"],"affected":[{"vendor":"openclaw","product":"openclaw","versions":[{"version":"< 2026.2.14","status":"affected"}]}],"references":["https://github.com/openclaw/openclaw/security/advisories/GHSA-cv7m-c9jx-vg7q","https://github.com/openclaw/openclaw/commit/3aa94afcfd12104c683c9cad81faf434d0dadf87","https://github.com/openclaw/openclaw/releases/tag/v2026.2.14"],"weaknesses":["CWE-22"],"ingestedAt":"2026-10-29T20:11:21.040Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/26xxx/CVE-2026-26329.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-26329","state":"PUBLISHED","datePublished":"2026-02-19T23:06:37.962Z","dateUpdated":"2026-02-20T15:38:37.988Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-13T16:27:51.809Z"},"containers":{"cna":{"title":"OpenClaw has a path traversal in browser upload allows local file read","descriptions":[{"lang":"en","value":"OpenClaw is a personal AI assistant.
