{"id":"CVE-2026-28459","summary":"OpenClaw \u003c 2026.2.12 - Arbitrary File Write via Untrusted sessionFile Path","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":"2026-08-17T03:55:01.558331856Z","published":"2026-03-05T21:59:37.255Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-73"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28459.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28459.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-64qx-vpxx-mvqf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-28459"},{"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openclaw/openclaw","events":[{"introduced":"0"},{"fixed":"d8d69ccbf464788a3ac0406b917d422ddf0dd84e"},{"fixed":"25950bcbb8ba4d8cde002557f6e27c219ae4deda"},{"fixed":"4199f9889f0c307b77096a229b9e085b8d856c26"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:openclaw:openclaw:*:*:*:*:*:node.js:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2026.2.12"}]}}],"versions":["v2026.2.12","v2026.2.9","v2026.2.6-3","v2026.2.6-2","v2026.2.6-1","v2026.2.6","v2026.2.3","v2026.2.2","v2026.2.1","v2026.1.30","v2026.1.29","v2026.1.24-1","v2026.1.24","v2026.1.23","v2026.1.22","v2026.1.21","v2026.1.20","v2026.1.16-2","v2026.1.15","v2026.1.14-1","v2026.1.13","v2026.1.12-2","v2026.1.12","v2026.1.11-3","v2026.1.11-2","v2026.1.11-1","v2026.1.11","v2026.1.10","v2026.1.9","v2026.1.8","v2026.1.5-3","v2026.1.5-2","v2026.1.5-1","v2026.1.5","v2.0.0-beta5","v2.0.0-beta4","v2.0.0-beta3","v2.0.0-beta2","v2.0.0-beta1","v1.3.0","v1.2.2","v1.2.1","v1.2.0","v1.1.0","v1.0.4","v0.1.3","v0.1.2","v0.1.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-28459.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N"}]}
