What to do
AI-suggested
Since fixed versions are identified as 0.12.6 and 13.0.5, upgrading Prosody to at least these versions is recommended to mitigate the vulnerability. If upgrading is not immediately possible, disabling the mod_proxy65 module can prevent exploitation.
Description
A vulnerability in Prosody versions before 0.12.6 and from 1.0.0 through 13.0.0 before 13.0.5 affects the mod_proxy65 module. The issue arises from improper access control handling during activation, allowing unauthenticated traffic to be relayed through the server.
