CVE-2024-10855Network attack vector

Authenticated denial of service via option deletion

Published Nov 20, 2024 · Updated Apr 8, 2026

Authorization bypass in the Sirv WordPress plugin 7.3.0 and earlier allows remote authenticated users to delete arbitrary site options. The sirv_upload_file_by_chunks() function insufficiently validates its filename parameter, allowing that value to select an arbitrary WordPress option for deletion. Contributor-level access is sufficient, and deleting a required option can trigger a site error that denies service to legitimate users.
