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.
CVE-2026-32757
MEDIUMPre-NVD 5.45.4
EchelonGraph scoreLOW confidence
This medium-severity CVE scores 5.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
