Description
The Subscribe To Comments Reloaded WordPress plugin up to version 240119 contains a vulnerability that allows unauthorized actors to access and modify comment subscription preferences. This is due to a leaked secret key and the use of a weak hash generation algorithm, enabling attackers to extract the global key from any public post page and forge authorization keys. The vulnerability has a CVSS score of 6.5, indicating medium severity. No official patch or remediation guidance is currently available from the vendor. There are no known exploits in the wild at this time.
