CVE-2026-97642 Details
Description
The Wp Parsidate plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the calendar Gutenberg block's 'theme' attribute in versions up to, and including, 6.4. This is due to insufficient input sanitization and output escaping on the block attribute value which is concatenated directly into an HTML class attribute in the printCalendar() function without esc_attr(). 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.
A stored cross-site scripting vulnerability has been identified in the Wp Parsidate plugin for WordPress, affecting versions through 6.4. The issue arises in the calendar Gutenberg block, where the 'theme' attribute is improperly sanitized and escaped. This flaw allows authenticated attackers with Contributor-level access or higher to inject arbitrary scripts into pages, which are executed when a user views the affected page.
Users are advised to update the Wp Parsidate plugin to version 6.5 or a newer patched version.
