CVE-2026-39507 describes a Stored Cross-Site Scripting (XSS) vulnerability within the Social Slider Feed plugin for WordPress. This flaw allows unauthenticated attackers to inject arbitrary web scripts, potentially leading to account compromise, data theft, or defacement of the website. The vulnerability impacts versions of the plugin up to and including 2.3.2, and a patch is available in version 2.3.3.
Successful exploitation of CVE-2026-39507 allows an attacker to inject malicious JavaScript code into pages served by the Social Slider Feed plugin. When a user visits a page containing the injected script, the script executes in their browser context, with the same privileges as the user. This can be used to steal session cookies, redirect users to phishing sites, or deface the website. The impact is particularly severe if the website is used for sensitive operations, such as e-commerce or banking, as attackers could potentially gain access to user accounts and financial data. The stored nature of the XSS means the injected script persists until removed, potentially affecting numerous users over time.
CVE-2026-39507 was publicly disclosed on 2026-04-16. No public proof-of-concept exploits are currently known, but the XSS nature of the vulnerability makes it likely that exploits will emerge. The CVSS score of 7.2 (HIGH) indicates a significant risk. Monitor security advisories and vulnerability databases for updates.
Websites using the Social Slider Feed plugin, particularly those running older versions (≤2.3.2), are at risk. Shared hosting environments where multiple websites share the same server infrastructure are especially vulnerable, as a compromise of one site could potentially lead to the compromise of others.
