CVE-2026-8885
Received Received - Intake
Stored XSS in DeMomentSomTres Shortcodes WordPress Plugin

Publication date: 2026-06-02

Last updated on: 2026-06-02

Assigner: Wordfence

Description
The DeMomentSomTres Shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'callout' shortcode in all versions up to, and including, 1.1.1. This is due to insufficient input sanitization and output escaping on the 'width' and 'align' shortcode attributes within the st_callout() function, which concatenates the attribute values directly into an HTML style attribute. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

AI Powered Q&A
Can you explain this vulnerability to me?

The DeMomentSomTres Shortcodes plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in its 'callout' shortcode up to version 1.1.1. This vulnerability arises because the plugin does not properly sanitize or escape input for the 'width' and 'align' attributes in the st_callout() function. These attribute values are directly inserted into an HTML style attribute, allowing an authenticated attacker with contributor-level access or higher to inject malicious scripts. These scripts execute whenever any user views the affected page.


How can this vulnerability impact me? :

This vulnerability can allow an attacker with contributor-level access to inject arbitrary malicious scripts into pages on a WordPress site using the vulnerable plugin. When other users visit these pages, the injected scripts execute in their browsers, potentially leading to theft of user credentials, session hijacking, defacement, or other malicious actions. This compromises the security and integrity of the website and its users.
