Unauthenticated object injection via unsafe deserialization
Published Aug 13, 2024 · Updated Apr 28, 2026
PHP object injection in Participants Database 2.5.9.2 and earlier allows remote attackers to inject objects through form submissions. The form-submission path passes attacker-controlled serialized values into PHP deserialization without preventing object instantiation. No known POP chain exists in the plugin itself; impact requires a usable chain from another installed plugin or theme and can include file deletion, data disclosure, or code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=2.5.9.2
- Affected versionversion=n/a <=2.5.9.2 changes=[{"at":"2.5.9.3","status":"unaffected"}]
