Last modified

CVE-2026-27523 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. OpenClaw versions prior to 2026.2.24 contain a sandbox bind validation vulnerability allowing attackers to bypass allowed-root and blocked-path checks via symlinked parent directories with non-existent leaf paths. Attackers can craft bind source paths that appear within allowed roots but resolve outside sandbox boundaries once missing leaf components are created, weakening bind-source isolation enforcement.. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
