Description

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.

Analysis

OpenClaw prior to commit b57b680 allows authenticated users to bypass the approval system by exploiting inconsistent environment variable normalization between approval validation and execution paths. An attacker with low privileges can inject non-portable environment variable keys that are filtered during operator review but accepted at runtime, potentially enabling execution of attacker-controlled binaries. …
