CVE-2024-12623 is a stored cross-site scripting vulnerability (CWE-79) in the ivmartel DICOM Support WordPress plugin, affecting all versions up to and including 0.10.6. The issue stems from improper neutralization of input in the 'dcm' shortcode, where user-supplied attributes are not adequately sanitized or escaped before output. Authenticated attackers with contributor-level privileges or higher can exploit this to inject arbitrary JavaScript that executes in the context of other users viewing the injected page. This vulnerability can lead to limited confidentiality and integrity impacts but does not affect availability. The CVSS 3.1 vector indicates network attack vector, low attack complexity, privileges required, no user interaction, and scope change.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the 'dcm' shortcode. These scripts execute in the browsers of users who view the compromised pages, potentially leading to information disclosure or manipulation of content within the affected site context. The impact is limited to confidentiality and integrity, with no direct availability impact. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the DICOM Support plugin if possible. Monitor for updates from ivmartel regarding a security patch addressing this vulnerability.
