CVE-2026-5425
CWE-79Published: April 4, 2026· Updated: Apr 7, 2026
Official Description
The Widgets for Social Photo Feed plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'feed_data' parameter keys in all versions up to, and including, 1.7.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Technical Analysis
CVE-2026-5425 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
