Medium (6.5). EPSS 0.2% chance of exploitation in the next 30 days.
The Subscribe To Comments Reloaded plugin for WordPress is vulnerable to unauthorized modification of data due to a leaked secret key and usage of a weak hash generation algorithm in all versions up to, and including, 240119. This makes it possible for unauthenticated attackers to extract the global key from any public post page, forge authorization keys and manage comment subscription preferences for arbitrary users
