 "title": "Live Composer <= 2.1.22 - Authenticated (Contributor+) Stored Cross-Site Scripting via Pagination Module Options",
 "description": "The Live Composer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the pagination type and pagination text module options in all versions up to, and including, 2.1.22, due to insufficient input validation and output escaping in the shared dslc_post_pagination() helper used by the post listing modules. 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.",
