This vulnerability in the WP Last Modified plugin allows an attacker with high privileges and requiring user interaction to inject and store malicious scripts due to improper input sanitization during page generation. The vulnerability can lead to a cross-site scripting attack that impacts confidentiality, integrity, and availability to a limited extent. The affected versions include all versions up to 0.1. No patch or official fix information is provided in the available data.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of users viewing the affected pages, potentially leading to limited confidentiality, integrity, and availability impacts as indicated by the CVSS vector. The attack requires high privileges and user interaction, which limits the ease of exploitation. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict high privilege user access to the plugin and avoid exposing it to untrusted users. Monitor for updates from the vendor regarding patches or mitigations.
