CVE-2023-1868Network attack vector

Unauthenticated cache deletion via unchecked GET parameter

Published Apr 5, 2023 · Updated Apr 8, 2026

Missing authorization in Plugin Builders YourChannel 1.2.3 and earlier allows remote attackers to clear its plugin cache via a GET request. The request path treats the presence of the yrc_clear_cache parameter as sufficient to clear cached data without checking a WordPress capability. No account or user interaction is required; the established consequence is deletion of cached plugin data, not control of site content or configuration.
