CVE-2026-11598 describes a stored cross-site scripting vulnerability in the Shortcodify plugin for WordPress. The issue exists in the handling of the 'name' shortcode attribute, where input is not properly sanitized or escaped before being rendered in web pages. Authenticated attackers with contributor-level access or above can exploit this to inject arbitrary scripts that execute in the context of users visiting the compromised pages. The vulnerability affects all versions up to and including 1.4.3. The CVSS 3.1 base score is 5.0, reflecting a medium severity with network attack vector, low attack complexity, and privileges required at the low level, but no user interaction needed. Confidentiality impact is low, with no integrity or availability impact reported. No official patch or remediation guidance is currently documented.

An attacker with contributor-level or higher privileges can inject persistent malicious scripts into pages via the 'name' shortcode attribute. These scripts execute in the browsers of users who view the injected pages, potentially leading to session hijacking, defacement, or other client-side attacks. The impact is limited to confidentiality with no direct integrity or availability effects. The vulnerability requires authenticated access, reducing the attack surface.

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 Shortcodify plugin if possible. Monitor for updates from the vendor regarding patches or official mitigations.
