Description
The Bilingual Linker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the bl_otherlang_link_1 parameter in all versions up to, and including, 2.4 due to insufficient input sanitization and output escaping. 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.
