CVE-2025-47468

Vulnerability

Description

The Hash Form plugin for WordPress (versions up to and including 1.2.8) contains a Cross-Site Request Forgery (CSRF) vulnerability [1]. CSRF attacks occur when an attacker tricks a logged-in user into unknowingly performing actions on a web application without their consent. The root cause is the lack of or insufficient anti-CSRF token validation in the plugin's request handling, which could allow an attacker to forge requests on behalf of an authenticated administrator or other privileged user.

Exploitation

Method

Exploitation of this vulnerability requires user interaction. An attacker must convince a privileged user—such as an administrator—to click a malicious link, visit a crafted page, or submit a specially designed form while they are logged into the WordPress site [1]. This interaction can be achieved through social engineering, such as embedding the malicious request in an email or a comment. No authentication from the attacker is needed beyond tricking the authenticated user.

Impact

Successful exploitation could allow an attacker to force the targeted user to perform unintended actions under their current session [1]. Depending on the permissions of the victim, this might include changing plugin settings, modifying forms, or other administrative actions that could compromise the integrity of the WordPress installation. The CVSS score is 4.3 (Medium), indicating a moderate severity [1].

Mitigation

The vulnerability has been addressed in version 1.2.9 of the Hash Form plugin [1]. Users are strongly advised to update to this version or later as soon as possible. If updating is not immediately possible, consult with a hosting provider or web developer for alternative measures. Patchstack users can enable auto-update for vulnerable plugins [1].
