CVE-2026-5425 is a stored cross-site scripting vulnerability in the trustindex Widgets for Social Photo Feed WordPress plugin. The issue is due to improper neutralization of input during web page generation, specifically via the 'feed_data' parameter keys. This allows unauthenticated attackers to inject malicious scripts that execute in the context of users visiting the affected pages. The vulnerability affects all versions up to and including 1.7.9. The CVSS 3.1 base score is 7.2 (AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, no privileges required, no user interaction, scope change, and low impact on confidentiality and integrity with no impact on availability.

Successful exploitation allows an unauthenticated attacker to execute arbitrary JavaScript in the context of users visiting the vulnerable pages, potentially leading to session hijacking, defacement, or other client-side impacts. The vulnerability affects confidentiality and integrity with low impact and does not affect availability. There are no known exploits in the wild currently.
