Descriptions

Auth. Stored (contributor+) Cross-Site Scripting (XSS) vulnerability in WordPress core 6.3 through 6.3.1, from 6.2 through 6.2.2, from 6.1 through 6.1.3, from 6.0 through 6.0.5, from 5.9 through 5.9.7 and Gutenberg plugin <= 16.8.0 versions.

Vulnerabilidad de Coss-Site Scripting (XSS) autenticada (con permisos de colaboradores o superiores) almacenada en WordPress core 6.3 a 6.3.1, de 6.2 a 6.2.2, de 6.1 a 6.1.3, de 6.0 a 6.0.5, de 5.9 a 5.9.7 y versiones del complemento Gutenberg en versiones &lt;= 16.8.0.

WordPress Core is vulnerable to Stored Cross-Site Scripting via the arrow navigation block attributes in versions between 5.9 and 6.3.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with contributor-level privileges and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
