CVE-2025-62097

Vulnerability

Overview The SEO Slider plugin for WordPress (versions from n/a through 1.1.1) contains a Cross-site Scripting (XSS) vulnerability caused by improper neutralization of user input during web page generation [1]. This is classified as a DOM-based XSS issue, meaning the payload is executed in the victim's browser on the client side rather than during server-side processing. The vulnerability can be triggered by a malicious role with the required privileges [1].

Attack

Vector and Exploitation Exploitation requires a privileged user to interact with a crafted link, page, or form [1]. An attacker who already has some level of access (e.g., an editor or author role) could inject malicious script input that is not properly sanitized. When another user (including an administrator) visits the affected page, the injected script executes in their browser session.

Potential

Impact A successful attack allows the adversary to inject arbitrary HTML or JavaScript into the website's frontend [1]. This can be used to redirect visitors to malicious sites, display unwanted advertisements, steal session cookies, or perform other client-side attacks. While the CVSS base score is 6.5 (Medium), the reference notes that such vulnerabilities are often leveraged in mass-exploit campaigns targeting thousands of websites [1].

Mitigation and

Remediation The only complete fix is to update the SEO Slider plugin to a patched version beyond 1.1.1 [1]. As an immediate measure, site administrators should upgrade the plugin or remove it if an update is unavailable. If updating is not possible, users should contact their hosting provider or a web developer for assistance [1]. No other workarounds are described in the advisory.
