CVE-2026-9691Public exploitNetwork attack vector

Object injection via unserialized form values

Published Jun 15, 2026 · Updated Jun 15, 2026

PHP object injection in CRM Perks Integration for ActiveCampaign 1.1.1 and earlier allows remote attackers to inject objects via form submissions. In cf7-active-campaign.php, form-processing code passes each nonarray field value to maybe_unserialize() without validating whether the serialized object is safe. No authentication is required; file deletion, sensitive-data retrieval, or code execution requires a usable POP chain from another installed plugin or theme.
