CVE-2026-34426

6.9 mediumEPSS 0.3%

Medium (6.9) in openclaw openclaw. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in openclaw 2026.3.22, 2026.4.2.

OpenClaw versions prior to commit b57b680 contain an approval bypass vulnerability due to inconsistent environment variable normalization between approval and execution paths, allowing attackers to inject attacker-controlled environment variables into execution without approval system validation. Attackers can exploit differing normalization logic to discard non-portable keys during approval processing while accepting them at execution time, bypassing operator review and potentially influencing runtime behavior including execution of attacker-controlled binaries.
