OpenClaw < 2026.3.31 - Exec Allowlist Bypass via Shell Init-File Options

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.16% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. Special conditions such as timing or configuration are required.
  • Fixed version: OpenClaw OpenClaw 2026.3.31.

Low priority for now. Upgrade to OpenClaw OpenClaw 2026.3.31 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

OpenClaw before 2026.3.31 contains an exec allowlist bypass vulnerability allowing attackers to inherit allowlist trust via shell init-file wrapper invocations. Attackers can exploit shell options like --rcfile, --init-file, and --startup-file to load attacker-chosen initialization files while bypassing exec allowlist matching restrictions.
