What is CVE-2026-2434?

The Pz-LinkCard plugin for WordPress is exploitable through a Stored Cross-Site Scripting vulnerability affecting the 'blogcard' shortcode attributes. This flaw emerges from inadequate input sanitization and output escaping, allowing authenticated attackers with Contributor-level access or higher to embed malicious scripts in pages. When a user accesses a compromised page, the injected scripts execute, potentially leading to unauthorized actions or data exposure.
