CVE-2021-32919 is a high-severity vulnerability affecting Prosody versions prior to 0.11.9, as well as various Debian and Fedora distributions. It stems from an undocumented experimental feature, "dialback_without_dialback," which fails to properly authenticate remote server certificates. This flaw allows an unauthenticated remote attacker to impersonate another server, leading to potential data compromise (CVSS 7.5, CWE-295). While no active exploitation, public exploit code, or significant community discussion has been observed, the vulnerability presents a significant risk if the affected option is enabled.
