My Album Gallery Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the My Album Gallery plugin for WordPress, affecting all versions through 1.0.4. The issue arises from inadequate input sanitization and output escaping, allowing authenticated attackers with Contributor-level access or higher to inject arbitrary scripts via the 'style_css' shortcode attribute. These scripts are executed when users access the affected pages.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.

Remediation

No known patch is available. It is recommended to uninstall the affected plugin and find a replacement.
