Description
The Falang multilanguage for WordPress plugin before 1.4.6 does not perform a capability check when saving term translations, and exposes a valid nonce to any logged-in user through an unprotected handler, allowing users with Subscriber-level access and above to store content that is later output without proper escaping, leading to Stored Cross-Site Scripting that executes in the context of higher-privileged users such as administrators.
