• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Issue This update addresses a critical security issue. We strongly recommend that you apply it as soon as possible.

In Changelog I found this

for Plesk Obsidian 18.0.74 Update 2 and Plesk Obsidian 18.0.73 Update 5.

If this is so very important, why is no corresponding notification sent to the admin account by email? I receive an email when an update has been installed automatically, but not when urgent action is required? Or has anyone received such a notice?
 
What is the actual security issue ??

And no for security issues Plesk should do a better job of notifying owners of licenses.

I’ve shared a suggestion regarding this issue in the Plesk Suggestions and Feedback forum for Plesk to improve security notifications:

 
Hi,

I would edit but you only give people a few minutes to edit or delete

Unbelievable this is a ROOT level Vulnerability!!!

This is the actual vulnerability

And



No where is it even clearly shown that this affects earlier Plesk Versions and those just have clunky workarounds!!

Unacceptable Plesk!!
