Last modified

CVE-2026-28463 is a high-severity vulnerability rated 8.6/10 on the CVSS scale. OpenClaw versions prior to 2026.2.14 contain an arbitrary file read vulnerability in the exec-approvals allowlist validation that checks pre-expansion argv tokens but executes using real shell expansion. Attackers with authorization or through prompt-injection attacks can exploit safe binaries like head, tail, or grep with glob patterns or environment variables to disclose files readable by the gateway or node process when host execution is enabled in allowlist mode.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
