MEDIUM 6.4

DescriptionCVE.org

The Image Alt Text Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the post title in all versions up to, and including, 1.8.2. This is due to insufficient input sanitization and output escaping when dynamically generating image alt and title attributes using a DOM parser. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

AnalysisAI

A Stored Cross-Site Scripting (XSS) vulnerability exists in the Image Alt Text Manager plugin for WordPress (all versions up to 1.8.2) due to insufficient input sanitization and output escaping when dynamically generating image alt and title attributes via DOM parser. Authenticated attackers with Author-level access or higher can inject arbitrary JavaScript through post titles, which executes when other users visit affected pages. With a CVSS score of 6.4 and confirmed reporting by Wordfence, this vulnerability affects SEO-focused WordPress installations relying on this plugin for bulk alt text management.

Technical ContextAI

The vulnerability resides in the Image Alt Text Manager plugin (CPE: cpe:2.3:a:wpsaad:image_alt_text_manager_–_bulk_&_dynamic_alt_tags_for_image_seo_optimization_+_ai) and stems from a CWE-79 (Improper Neutralization of Input During Web Page Generation) flaw. The plugin's DOM parser, specifically in the alm-empty-generator.php file (lines 150 and 295 per WordPress plugin repository), fails to properly escape or sanitize post title input before embedding it into dynamically generated HTML attributes. When the plugin processes post titles to auto-generate alt text and title attributes for images, untrusted user input flows directly into these attributes without sanitization, allowing script injection. The root cause is inadequate use of WordPress sanitization functions (such as sanitize_text_field() or wp_kses_post()) and missing output escaping (such as esc_attr()) at the point where post titles are rendered into HTML.

RemediationAI

Immediately upgrade the Image Alt Text Manager plugin to a version newer than 1.8.2; check the official WordPress plugin repository (https://plugins.trac.wordpress.org/browser/alt-manager/) or the plugin's update mechanism in the WordPress admin dashboard for the patched version. Until patching is complete, restrict Author-level access to trusted contributors only, disable the plugin if not actively required, and use WordPress user role management to limit who can create or edit posts. Additionally, implement Content Security Policy (CSP) headers to mitigate stored XSS impact by preventing inline script execution. For affected WordPress multisite installations, consider temporarily restricting plugin functionality via code or temporarily reverting to manual alt text management until a verified patch is confirmed available.
