This is due to insufficient sanitization in strip_php_tags_deep(), which only strips literal '<?' sequences, combined with a post-interpolation placeholder cleanup that reassembles a valid '<?php' opener after the attacker-controlled value has already been embedded in the email template. This makes it possible for authenticated attackers, with custom-level access and above, to execute code on the server.","dueDate":"","id":"CVE-2026-86596","kev_catalogs":["vulncheck"],"knownRansomwareCampaignUse":"Unknown","product":"s2Member","requiredAction":"Apply remediations or mitigations per vendor instructions or discontinue use of the product if remediation or mitigations are unavailable.","severity":"HIGH","source":"vulncheck_kev","title":"CLavaque s2Member Improper Control of Generation of Code","vendor":"CLavaque"}
