CVE-2026-92422: Unknown Meow Gallery

Medium severity, CVSS 6.5. EPSS: 0.2% chance of exploitation in the next 30 days.

The Meow Gallery WordPress plugin before 5.5.5 does not properly sanitize a user-supplied value before concatenating it into a shortcode string that it passes to the WordPress shortcode parser on a publicly reachable endpoint, allowing unauthenticated users to execute arbitrary registered shortcodes and disclose non-public gallery content.
