Apache: >> Pony Mail Security Vulnerabilities
** UNSUPPORTED WHEN ASSIGNED ** Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') vulnerability in Pony Mail leading to admin account takeover.
This issue affects all versions of the Lua implementation of Pony Mail. There is a Python implementation under development under the name "Pony Mail Foal" that is not affected by this issue, but hasn't been released yet.
As the Lua implementation of this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users.

The statistics generator in Apache Pony Mail 0.7 to 0.9 was found to be returning timestamp data without proper authorization checks. This could lead to derived information disclosure on private lists about the timing of specific email subjects or text bodies, though without disclosing the content itself. As this was primarily used as a caching feature for faster loading times, the caching was disabled by default to prevent this. Users using 0.9 should upgrade to 0.10 to address this issue.
