CVE-2025-29003 is a Cross Site Scripting (XSS) vulnerability in the WordPress plugin "The Holiday Calendar" up to version 1.18.2.1. It allows an attacker with contributor-level privileges to inject malicious scripts, such as redirects, advertisements, or other HTML payloads, into the website. These scripts execute when visitors access the site, potentially compromising user interactions and site integrity. [1]
How can this vulnerability impact me? :
This vulnerability can impact you by allowing attackers to execute malicious scripts on your website, which can lead to unauthorized redirects, display of unwanted advertisements, or other harmful HTML content. This can degrade user trust, harm your website's reputation, and potentially lead to further security issues depending on the exploitation context. [1]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring for suspicious script injections or unexpected HTML payloads in the website content, especially from users with contributor-level privileges. However, plugin-based malware scanners may be unreliable for detecting this issue. No specific commands are provided for detection. It is recommended to seek professional incident response or hosting provider assistance for thorough detection. [1]
