Last modified

CVE-2026-28482 is a high-severity vulnerability rated 8.4/10 on the CVSS scale. OpenClaw versions prior to 2026.2.12 construct transcript file paths using unsanitized sessionId parameters and sessionFile paths without enforcing directory containment. Authenticated attackers can exploit path traversal sequences like ../../etc/passwd in sessionId or sessionFile parameters to read or write arbitrary files outside the agent sessions directory.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
