CVE-2026-28459

Ein Angreifer kann diese Schwachstellen in OpenClaw ausnutzen, um beliebigen Programmcode auszuführen, sich erhöhte Berechtigungen zu verschaffen, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren, einen Denial-of-Service-Zustand herbeizuführen, vertrauliche Informationen offenzulegen oder andere, nicht näher bezeichnete Angriffe durchzuführen.

## Summary In OpenClaw versions prior to 2026.2.12, the gateway accepted an untrusted `sessionFile` path when resolving the session transcript file. This could allow an authenticated gateway client to create and append OpenClaw session transcript records at an arbitrary path on the gateway host. ## Affected Versions - Affected: openclaw `< 2026.2.12` - Patched: openclaw `>= 2026.2.12` (recommended: `>= 2026.2.13`) ## Impact An authenticated gateway client could influence where the gateway writes transcript data by supplying `sessionFile` outside of the sessions directory. Depending on deployment and filesystem permissions, this may enable arbitrary file creation and repeated appends, leading to configuration corruption and/or denial of service. This issue does not, by itself, provide a proven remote code execution path. ## Fix The transcript path is now constrained to the sessions directory via `resolveSessionFilePath(...)` containment checks. Fix commits: - 4199f9889f0c307b77096a229b9e085b8d856c26 - (compat) 25950bcbb8ba4d8cde002557f6e27c219ae4deda ## Credits Thanks to @tubadeligoz for the report.
