This vulnerability (CVE-2025-23652) involves improper neutralization of input in the 'Add custom content after post' plugin by Fabio Zuanon, resulting in reflected cross-site scripting (XSS). It affects all versions up to and including 1.0. The CVSS 3.1 base score is 7.1, indicating a high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability. No patch or vendor advisory is currently available to confirm remediation status.

Successful exploitation of this reflected XSS vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to limited disclosure of information, modification of data, or disruption of service. The CVSS vector indicates that exploitation requires user interaction but no privileges, and it can be triggered remotely over the network.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling or removing the affected plugin if feasible, and apply standard XSS mitigations such as input validation and output encoding where possible.
