CVE-2025-13896 is a stored cross-site scripting vulnerability in the Social Feed Gallery Portfolio WordPress plugin (versions up to and including 1.3). It occurs due to improper neutralization of input in the 'id' parameter of the [igp-wp] shortcode, allowing authenticated users with Contributor or higher privileges to inject arbitrary web scripts. These scripts execute in the context of users who access the injected pages, potentially leading to session hijacking or other script-based attacks. The vulnerability has a CVSS 3.1 score of 6.4 (medium severity), with network attack vector, low attack complexity, and no user interaction required. No patch or official fix has been documented yet.

An attacker with Contributor-level or higher access can store malicious scripts via the vulnerable shortcode parameter, which execute in the browsers of users who view the infected pages. This can lead to information disclosure or session hijacking. The vulnerability does not affect availability and requires authenticated access, limiting its impact to environments where such users exist.

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 Social Feed Gallery Portfolio plugin if possible to prevent exploitation.
