CVE-2026-32757 Details
Description
Admidio is an open-source user management solution. In versions 5.0.6 and below, the eCard send handler uses a raw $_POST['ecard_message'] value instead of the HTMLPurifier-sanitized $formValues['ecard_message'] when constructing the greeting card HTML. This allows an authenticated attacker to inject arbitrary HTML and JavaScript into greeting card emails sent to other members, bypassing the server-side HTMLPurifier sanitization that is properly applied to the ecard_message field during form validation. An attack can result in any member or role receiving phishing content that appears legitimate, crossing from the web application into recipients' email clients. This issue has been fixed in version 5.0.7.
A vulnerability in Admidio's eCard send handler prior to version 5.0.7 allows authenticated attackers to inject arbitrary HTML and JavaScript into greeting card emails. This issue arises because the handler uses a raw POST value for the eCard message, bypassing proper sanitization by HTMLPurifier. As a result, injected content can be delivered to other members as part of the eCard, potentially leading to phishing attacks. The vulnerability exploits a flaw in how user input is processed and sanitized before being included in outgoing emails.
Users are advised to update to Admidio version 5.0.7 or later, where this vulnerability has been fixed.
