CVE-2024-4386
The Gallery Block (Meow Gallery) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘data_atts’ parameter in versions up to, and including, 5.1.3 due to insufficient input sanitization and output escaping.
Does this matter?
Lower severity and a low EPSS score (0.45%). Track it; it rarely justifies an emergency change on its own.
Description
The Gallery Block (Meow Gallery) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘data_atts’ parameter in versions up to, and including, 5.1.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
