CVE-2025-62749

Vulnerability

Description CVE-2025-62749 is a DOM-Based Cross-Site Scripting (XSS) vulnerability in the Bainternet User Specific Content plugin for WordPress, versions up to and including 1.0.6. The flaw stems from improper neutralization of input during web page generation, allowing attacker-controlled data to be executed as script code within the browser's DOM [1].

Exploitation

Prerequisites To exploit this vulnerability, a privileged user—such as an administrator—must perform an action like clicking a crafted link or visiting a specially prepared page [1]. No prior authentication on the target site is required for the attacker to deliver the payload, but the victim's interaction is necessary for execution.

Impact and

Attack Scenarios Successful exploitation permits an attacker to inject arbitrary HTML and JavaScript into the victim's browser session [1]. This can be leveraged to redirect visitors to malicious sites, display unwanted advertisements, steal session tokens, or perform other actions under the guise of the legitimate site context.

Mitigation and

Patch Status The vendor has addressed this issue in a plugin update; users are strongly advised to upgrade to the latest available version immediately [1]. If upgrading is not possible, consulting a hosting provider or web developer is recommended to apply temporary workarounds or alternative protections.
