Vulnerability mechanics

Root cause

"Missing input validation and output escaping on the "Logo Margin" carousel option allows stored cross-site scripting."

Attack vector

An attacker with a Contributor-level role (or higher) can inject arbitrary JavaScript into the "Logo Margin" carousel option. Because the plugin fails to validate and escape this option, the injected script is stored and later executed in the browsers of users who view the carousel [ref_id=1]. This is a classic Stored Cross-Site Scripting (XSS) attack path [CWE-79].

Affected code

The "Logo Margin" carousel option in the Logo Carousel WordPress plugin (logo-carousel-free) is the vulnerable field. The plugin does not validate or escape this option before storing or rendering it [ref_id=1]. No specific function or file path is named in the advisory.

What the fix does

The advisory states the vulnerability is fixed in version 3.4.2 of the plugin [ref_id=1]. No patch diff is provided in the bundle, so the specific code changes are unknown. The fix presumably adds proper input validation and output escaping to the "Logo Margin" option to prevent stored script injection.

Preconditions

  • authAttacker must have at least a Contributor-level role on the WordPress site
  • configThe Logo Carousel plugin must be installed and activated with version prior to 3.4.2
  • inputAttacker must have access to edit or create a carousel with the 'Logo Margin' option
