Other vulnerabilities in Easy Accordion

CVE-2026-18988Medium
The Easy Accordion plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'accordionTitleTag' block attribute in versions up to and including 3.1.8. This is due to insufficient input sanitization and output escaping in the accordion_header_renderer() function, which emits the attacker-supplied tag name using esc_attr() in an HTML tag-name context instead of tag_escape(). This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts that execute when a user accesses an injected page.
