Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.5.7
Description An issue exists in the retry endpoint checks where hostname validation allows matching hostname prefixes instead of requiring exact hostnames. This allows attackers to craft a hostname prefix that resembles a trusted host, potentially leading to the transmission of authentication material to untrusted endpoints.
Recommendations Update to version 2026.5.7.
