CVE-2025-58248

Vulnerability

Overview The Pinterest Pinboard Widget plugin for WordPress (versions up to and including 1.0.7) contains a stored cross-site scripting (XSS) vulnerability due to improper neutralization of user input during web page generation. This flaw allows attackers to inject arbitrary HTML and JavaScript code that is stored on the server and executed when other users visit the affected page [1].

Exploitation

Details Exploitation requires an authenticated user with at least contributor-level privileges to submit a crafted payload via the plugin's input fields. The attack does not require direct user interaction from the victim; however, the stored script will execute automatically for any visitor viewing the compromised page. The vulnerability is classified as medium severity (CVSS 6.5) and is known to be used in mass-exploit campaigns targeting WordPress sites [1].

Impact

Successful exploitation enables an attacker to inject malicious scripts, such as redirects, advertisements, or other HTML payloads, into the website. These scripts execute in the context of the victim's browser, potentially leading to data theft, session hijacking, or defacement. The impact is amplified by the stored nature of the XSS, as the malicious content persists until removed [1].

Mitigation

The vendor has not released a patched version as of the publication date. Users are strongly advised to update the plugin to the latest version if available. If an update is not possible, immediate actions include disabling the plugin or implementing a web application firewall (WAF) to filter malicious input. Site administrators should also review and remove any suspicious content that may have been injected [1].
