Title
OpenClaw < 2026.2.1 - Inbound Allowlist Policy Bypass in voice-call Extension via Empty Caller ID and Suffix Matching
Summary
OpenClaw versions prior to 2026.2.1 with the voice-call extension installed and enabled contain an authentication bypass vulnerability in inbound allowlist policy validation that accepts empty caller IDs and uses suffix-based matching instead of strict equality. Remote attackers can bypass inbound access controls by placing calls with missing caller IDs or numbers ending with allowlisted digits to reach the voice-call agent and execute tools.
Severity ?
9.4 (Critical)
CWE
- Incorrect Implementation of Authentication Algorithm
