CVE-2025-23944Network attack vector

Authenticated object injection via untrusted PHP deserialization

Published Jan 22, 2025 · Updated May 11, 2026

PHP object injection in BulkTheme WOOEXIM 5.0.0 and earlier allows remote authenticated users to inject crafted serialized objects. Patchstack and the CNA record do not identify the affected parameter, function, file, or deserialization call that accepts the untrusted data. Subscriber-level access is required, and the resulting effects on site data, code, and service availability are not technically detailed.
