The Media Library Assistant plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'search-string' parameter in all versions up to, and including, 3.42 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Exploitation requires the targeted site to have a publicly accessible page containing an [mla_gallery] shortcode configured with a pagination output mode and an mla_link_href template that reflects a {+request:...+} token, along with enough attachments to trigger pagination.
The Media Library Assistant plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'mla_link_attributes' parameter in all versions up to, and including, 3.35 due to insufficient input sanitization and output escaping. 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.
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.
The Media Library Assistant plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'mla_gallery' shortcode in versions up to and including 3.35. This is due to insufficient input sanitization and output escaping on the mla_link_href parameter when mla_output is set to 'paginate_links', where the _paginate_links() function processes the value through mla_process_shortcode_parameter() and _replace_query_parameter() without proper URL escaping, then outputs it directly in href attributes without applying esc_url(). 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.
The Media Library Assistant plugin for WordPress is vulnerable to Cross-Site Request Forgery 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. This makes it possible for unauthenticated attackers to trick an administrator into performing bulk delete, edit, or purge operations on plugin settings and attachment metadata via a forged request.
The Media Library Assistant plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the mla_update_compat_fields_action() function in all versions up to, and including, 3.33. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify taxonomy terms on arbitrary attachments.
The Media Library Assistant plugin for WordPress is vulnerable to limited file reading in all versions up to, and including, 3.29 via the mla-stream-image.php file. This makes it possible for unauthenticated attackers to read the contents of arbitrary ai/eps/pdf/ps files on the server, which can contain sensitive information.
The Media Library Assistant plugin for WordPress is vulnerable to arbitrary file deletion in the /wp-content/uploads directory due to insufficient file path validation and user capability checking in the _process_mla_download_file function in all versions up to, and including, 3.27. This makes it possible for authenticated attackers, with Author-level access and above, to delete arbitrary files on the server from the /wp-content/uploads/ directory.
The Media Library Assistant plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's mla_tag_cloud and mla_term_list shortcodes in all versions up to, and including, 3.26 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
The Media Library Assistant plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘smc_settings_tab', 'unattachfixit-action', and 'woofixit-action’ parameters in all versions up to, and including, 3.23 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
The Media Library Assistant plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation involving the mla-inline-edit-upload-scripts AJAX action in all versions up to, and including, 3.18. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
The Media Library Assistant plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the order parameter in all versions up to, and including, 3.17 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
The Media Library Assistant plugin for WordPress is vulnerable to time-based SQL Injection via the ‘order’ parameter within the mla_tag_cloud Shortcode in all versions up to, and including, 3.16 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
The Media Library Assistant plugin for WordPress is vulnerable to SQL Injection via the plugin's shortcode(s) in all versions up to, and including, 3.15 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor access or higher, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
The Media Library Assistant plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the lang parameter in all versions up to, and including, 3.15 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
The Media Library Assistant plugin for WordPress is vulnerable to SQL Injection via the plugin's shortcode(s) in all versions up to, and including, 3.13 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor access or higher, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
The Media Library Assistant plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcodes in all versions up to, and including, 3.13 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
