The wpdevart Widget Countdown plugin versions up to 2.7.4 contain a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows an attacker with low privileges to inject malicious scripts that execute when a user views the affected page. The vulnerability requires user interaction and impacts confidentiality, integrity, and availability to a limited extent as reflected by the CVSS vector AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L. No patch or vendor advisory is currently available to confirm remediation status.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected website, potentially leading to limited disclosure of information, modification of data, or disruption of availability. The attack requires user interaction and low privileges, limiting the scope but still posing a risk to site users and administrators. No known active exploits have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider restricting user input where possible and applying web application firewall (WAF) rules to detect and block suspicious input patterns related to XSS. Monitor vendor channels for updates regarding patches or official mitigations.
