CVE-2026-1899

Description

The Any Post Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's aps_slider shortcode in all versions up to, and including, 1.0.4 due to insufficient input sanitization and output escaping on the 'post_type' attribute. 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.
