The mulscully Today's Date Inserter plugin (<= 1.2.1) suffers from a stored cross-site scripting (XSS) vulnerability caused by improper neutralization of input during web page generation. This allows an attacker with low privileges and requiring user interaction to inject malicious scripts that persist in the application, potentially affecting confidentiality, integrity, and availability of the affected system. The CVSS 3.1 base score is 6.5, reflecting network attack vector, low attack complexity, low privileges required, user interaction needed, and partial impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can result in stored XSS attacks, which may allow an attacker to execute arbitrary scripts in the context of the affected application. This can lead to partial compromise of confidentiality, integrity, and availability of the system or user data. However, no known exploits in the wild have been reported, and the impact is rated medium severity.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider limiting exposure by restricting privileges and user input where possible. Monitor vendor channels for updates and apply patches promptly once released.
