This vulnerability in WPChill Remove Footer Credit plugin (up to version 1.0.13) is classified as CWE-79, indicating improper neutralization of input leading to stored cross-site scripting. An attacker with high privileges and requiring user interaction can exploit this to inject malicious scripts that persist in the application. The CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L) reflects network attack vector, low attack complexity, high privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker with high privileges to execute arbitrary scripts in the context of affected users, potentially leading to partial disclosure of information, modification of data, and disruption of service. The impact is limited by the requirement for high privileges and user interaction. No known active exploitation has been reported.

No official patch or remediation is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, restrict access to trusted users with high privileges and exercise caution with user inputs related to footer credit customization.
