Plex has notified some of its users on Thursday to urgently update their media servers due to a recently patched security vulnerability.
The company has yet to assign a CVE-ID to track the flaw and didn’t provide additional details regarding the patch, only saying that it impacts Plex Media Server versions 1.41.7.x to 1.42.0.x.
I posted a while back, tested the biggest open endpoints and they were properly secured, the issues just weren’t updated.
Note: Plex didn’t have SSL, and refused to implement it, until ~6 weeks after I created a POC token exploit. Here’s the GitHub repo I posted as a patch before they got their system in order: https://github.com/Fmstrat/plex-ssl. In other words, don’t give them too much credit.
