Last modified Jun 17, 2026

CVE-2026-28363 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. In OpenClaw before 2026.2.23, tools.exec.safeBins validation for sort could be bypassed via GNU long-option abbreviations (such as --compress-prog) in allowlist mode, leading to approval-free execution paths that were intended to require approval. Only an exact string such as --compress-program was denied.. EPSS estimates a 0.50% chance of exploitation in the next 30 days.
