Improper Access Control in Discourse Community Platform
CVE-2024-56197
Summary
An issue in the Discourse community platform allows unauthorized users to read private message (PM) titles and metadata when certain group settings are enabled. Specifically, if the 'PM tags allowed for groups' option is activated and a user is a member of a group with PM tagging, they may access sensitive information from PMs that should be restricted. This vulnerability has been addressed in the latest versions of Discourse, and users are strongly encouraged to update their installations. For those who cannot upgrade immediately, it is recommended to disable the 'PM tags allowed for groups' option to mitigate the risk.
