Summary
The Media Library Assistant plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the bulk edit preset export/import mechanism in versions up to and including 3.35. Due to insufficient output escaping on preset field values in HTML attribute contexts, an authenticated attacker with Author-level access and above can inject malicious scripts that execute when an administrator imports the poisoned preset and the targeted input field receives focus.
Risk Assessment
An attacker with an Author account can inject scripts into the site that execute in an administrator's browser, potentially enabling session hijacking or actions with administrator privileges.
Recommendation
Update the Media Library Assistant plugin to a version newer than 3.35 and limit the number of accounts with Author-level or higher privileges.

The Media Library Assistant plugin for WordPress is vulnerable to Cross-Site Request Forgery (CSRF) in versions up to and including 3.35. This is due to missing nonce verification on the bulk action handlers in the settings tab handlers, allowing unauthenticated attackers to trick an administrator into performing bulk delete, edit, or purge operations on plugin settings and attachment metadata via a forged request.
Original NVD description (English source)
The Media Library Assistant plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the bulk edit preset export/import mechanism in versions up to and including 3.35. This is due to insufficient output escaping on preset field values when they are rendered in HTML attribute contexts in the mla_generate_bulk_edit_form_fieldsets() function and mla-bulk-edit-fieldsets.tpl template. While wp_kses() filtering is applied during preset export for users without unfiltered_html capability, this does not prevent attribute injection attacks since the malicious payload consists of quotes and HTML attributes rather than HTML tags. When preset values are retrieved and rendered, they are directly assigned to template variables without esc_attr() escaping and then inserted into input element value attributes via simple string replacement. This makes it possible for authenticated attackers, with Author-level access and above (upload_files capability), to inject arbitrary web scripts that execute when an administrator imports the poisoned preset and the targeted input field receives focus.
