The injection itself does not contain a vulnerable object, so a successful exploit depends on the presence of a remote object property (POP) chain in the system.

The EPSS score indicates a very low probability of exploitation (<1%), and it is not listed in the CISA KEV catalog. The likely attack vector is a direct, unauthenticated HTTP request to the download_csv function, where a crafted payload would cause object deserialization. Success requires a pre\u2011existing POP chain, such as another plugin or theme that contains a vulnerable class. Without that additional component the vulnerability is effectively mitigated, but the potential for catastrophic impact remains if a POP chain is present."}}}}, "created": "2026-03-06T15:07:41.611369+00:00", "updated": "2026-04-15T18:00:15.478796+00:00", "vendors": ["crmperks", "crmperks$PRODUCT$database_for_contact_form_7,_wpforms,_elementor_forms", "wordpress", "wordpress$PRODUCT$wordpress"]}
