The arildur Read More Login plugin suffers from a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This flaw affects versions up to and including 2.0.3. Exploitation requires high privileges and user interaction, and it can lead to partial confidentiality, integrity, and availability impacts as indicated by the CVSS vector. No patch or official fix details are currently available.

Successful exploitation could allow an attacker with high privileges to inject malicious scripts that execute in the context of other users, potentially leading to partial compromise of confidentiality, integrity, and availability of the affected system. However, exploitation requires user interaction and elevated privileges, which limits the ease of attack. No known active exploits have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should restrict access to trusted users with high privileges and monitor for suspicious activity related to the plugin. Avoid enabling untrusted input that could be stored and rendered by the Read More Login plugin.
