CVE-2026-2501

Vulnerability

The Ed's Social Share plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) through the social_share shortcode. The plugin fails to properly sanitize user-supplied attributes (such as text, color, and twitter) and does not escape output when rendering the shortcode, allowing arbitrary HTML and JavaScript injection [1].

Exploitation

Authenticated attackers with at least Contributor-level access can inject malicious scripts by crafting a shortcode with dangerous attribute values. The injected script becomes stored and executes whenever a user views the affected page or post. No additional authentication is required on the visitor side, making this potentially impactful for site users and administrators [1].

Impact

Successful exploitation allows an attacker to execute arbitrary scripts in the context of a victim's browser session. This can lead to session hijacking, defacement, redirection to malicious sites, or theft of sensitive information (such as cookies or authentication tokens) when a victim accesses the compromised page [1].

Mitigation

The vendor has not yet released a patched version; all versions up to and including 2.0 are affected. Site administrators should restrict contributor-level access to trusted users, disable the plugin until a fix is available, or apply strict output escaping and input validation as a temporary workaround. As of March 2026, no known mitigation script or update has been published [1].
