Does this matter?

Lower severity and a low EPSS score (0.52%). Track it; it rarely justifies an emergency change on its own.

Description

OpenClaw 2026.2.25 before 2026.5.26 allow a lower-trust caller or configured input path to bypass non-browser rate limits on WebSocket authentication attempts. When the affected feature is enabled and reachable by lower-trust input, this can consume gateway resources and reduce service availability.
