{"id":"CVE-2026-28459","details":"OpenClaw versions prior to 2026.2.12 fail to validate the sessionFile path parameter, allowing authenticated gateway clients to write transcript data to arbitrary locations on the host filesystem. Attackers can supply a sessionFile path outside the sessions directory to create files and append data repeatedly, potentially causing configuration corruption or denial of service.","aliases":["GHSA-64qx-vpxx-mvqf"],"modified":"2026-04-10T05:41:14.337427Z","published":"2026-03-05T22:16:18.670Z","references":[{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-arbitrary-file-write-via-untrusted-sessionfile-path"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/25950bcbb8ba4d8cde002557f6e27c219ae4deda"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/4199f9889f0c307b77096a229b9e085b8d856c26"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-64qx-vpxx-mvqf"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openclaw/openclaw","events":[{"introduced":"0"},{"fixed":"d8d69ccbf464788a3ac0406b917d422ddf0dd84e"},{"fixed":"25950bcbb8ba4d8cde002557f6e27c219ae4deda"},{"fixed":"4199f9889f0c307b77096a229b9e085b8d856c26"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"2026.2.12"}]}}],"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","v2026.2.2","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-2026-28459.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H"}]}
