Technical description

The The Broken Link Checker plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 2.4.14.1. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. Exploitation requires that a submitted comment containing the shortcode payload in an href or src attribute is approved through the site's normal comment moderation workflow; once approved, the shortcode is executed automatically via WP-Cron without any further attacker interaction.

This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode.

———The The Slim SEO – AI SEO Plugin, Lightweight, Fast & Automated plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 4.11.1 This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for authenticated attackers, with subscriber-level access and above, to execute arbitrary shortcodes. A Subscriber-level user need only save the shortcode payload to their own Biographical Info field via the REST API or wp-admin profile page; the shortcode then executes on any unauthenticated front-end request that resolves that author's description, such as requests using the ?author= query parameter when auto_redirection is disabled.7h CVE-2026-1039116.5 MED

———The The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 1.58.1. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. This is exploitable on any block-theme install via a single unauthenticated GET request to the search results page, or by submitting an anonymous comment on any post with comments enabled; no Forminator-specific content or configuration is required to trigger execution.8h CVE-2026-1013356.5 MED

———The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Arbitrary Shortcode Execution in versions up to, and including, 1.58.1. This is due to the forminator_replace_quiz_form_data() helper invoking do_shortcode() on the fully expanded notification body once the {quiz_result} merge tag has been substituted, while the earlier-substituted {user_agent} and {refer_url} merge tags carry unauthenticated attacker-controlled bytes (the User-Agent header and the referer_url POST parameter) through sanitize_text_field()/esc_html(), neither of which strip the '[' and ']' shortcode delimiters. This makes it possible for unauthenticated attackers to execute arbitrary WordPress shortcodes registered on the site by submitting a quiz whose notification template contains {quiz_result}; the resulting impact depends on the shortcodes exposed by other installed plugins/themes and can range from arbitrary content injection to information disclosure.8h CVE-2026-1112375.3 MED

———A weakness has been identified in Ultralytics FastSAM up to b4ed20c2fed75eadc5aa7d8b09fedd137b873b52. This affects the function session.get_modelmeta.custom_metadata_map of the file ultralytics/nn/autobackend.py of the component AutoBackend Model Loading. This manipulation of the argument imgsz/names/kpt_shape causes improper neutralization of directives in dynamically evaluated code. The attack requires local access. This product uses a rolling release model to deliver continuous updates. As a result, specific version information for affected or updated releases is not available. The project was informed of the problem early through an issue report but has not responded yet.10h
