CVE-2025-23988

CVE-2025-23988 is a reflected cross-site scripting (XSS) vulnerability in the WordPress Ghostwriter theme, affecting versions from n/a through 1.4. The root cause is improper neutralization of user-supplied input during web page generation, enabling an attacker to inject arbitrary HTML or JavaScript into the response. [1]

Exploitation requires a privileged user to perform an action, such as clicking a crafted link, submitting a form, or visiting a specially prepared page. The attacker does not need prior authentication against the target, but user interaction from an authenticated user is necessary. This class of vulnerability is often used in mass-exploit campaigns targeting thousands of websites simultaneously. [1]

Successful exploitation allows an attacker to execute malicious scripts in the context of the victim's browser, leading to actions such as redirecting visitors, displaying unwanted advertisements, or injecting HTML payloads. The CVSS v3 score is 7.1 (High), reflecting the potential for widespread impact with low attack complexity. [1]

No official vendor patch is available at the time of publication. Users are advised to update the theme as soon as a fix is released. If immediate updating is not possible, hosting providers or web developers should be consulted. Patchstack offers a mitigation rule to block attacks until an official patch can be safely deployed. [1]
