Does this matter?
Lower severity and a low EPSS score (0.20%). Track it; it rarely justifies an emergency change on its own.
Description
An issue was discovered in Prosody before 0.12.6 and 1.0.0 through 13.0.0 before 13.0.5, when mod_proxy65 is enabled. Because mod_proxy65 mishandles access control in the activation scenario, relaying of unauthenticated traffic can occur.
