Fix privilege escalation via harness allow-rules
Exploits target harness allow-rule approval. Review rules carefully to prevent broad access.
Users must carefully review and approve allow-rules proposed by coding agents. Be aware that adversarial context can lead to requests for broad permissions that bypass future oversight.
Privilege escalation attacks on coding agents
Untrusted context influences allow-rules presented for approval, leading to dangerous permissions.
Coding agents allow users to approve rules to reduce approval fatigue. Adversaries can plant context to trick users into approving overly broad rules, granting future unauthorized access. Vigilant review of all requested allow-rules is crucial.
