CVE-2026-0726 (GCVE-0-2026-0726)
Vulnerability from nvd – Published: 2026-01-20 14:26 – Updated: 2026-04-14 15:07

Title
Nexter Extension – Site Enhancements Toolkit <= 4.4.6 - Unauthenticated PHP Object Injection via 'nxt_unserialize_replace'
Summary
The Nexter Extension – Site Enhancements Toolkit plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.4.6 via deserialization of untrusted input in the 'nxt_unserialize_replace' function. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
Severity ?
8.1 (High)

Title
Nexter Extension <= 4.4.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode
Summary
The Nexter Extension – Site Enhancements Toolkit plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'nxt-year' shortcode in all versions up to, and including, 4.4.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
