CVE-2026-1542Public exploitNetwork attack vector

Unauthenticated object injection via bridge data deserialization

Published Feb 28, 2026 · Updated Feb 28, 2026

PHP object injection in Revmakx Super Stage WP before 1.0.2 allows remote attackers to inject objects through a public HTTP endpoint. Staging/bridge/bridge.php base64-decodes the data request parameter and unserializes it without authentication or validating its serialized contents. A suitable PHP gadget chain supplied by another installed plugin or theme is required to turn object injection into file deletion, data disclosure, or code execution.
