The mulscully Today's Date Inserter plugin versions up to 1.2.1 suffer from a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows an attacker with at least low privileges and requiring user interaction to inject malicious scripts that can affect confidentiality, integrity, and availability to a limited extent. The vulnerability has a CVSS 3.1 base score of 6.5, reflecting network attack vector, low attack complexity, privileges required, and user interaction needed with scope changed.

Successful exploitation of this stored XSS vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to limited confidentiality, integrity, and availability impacts. However, no known exploits are reported in the wild, and the impact is assessed as 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 privileges of users who can input data into the plugin and apply standard XSS mitigations where possible. Monitor vendor channels for updates regarding patches or official fixes.
