Assigner: mitre
Reserved: 01.05.2026 Published: 01.05.2026 Updated: 01.05.2026

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 a paused scenario, relaying of unauthenticated traffic can occur.
