The YourChannel plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check when clearing the plugin cache via the yrc_clear_cache GET parameter in versions up to, and including, 1.2.3. This makes it possible for unauthenticated attackers to clear the plugins cache.
Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Yourchannel | Plugin | * | 1.2.3 (including) |
