The project was informed of the problem early through an issue report but has not responded yet.

A security vulnerability has been detected in SourceCodester Online Boat Reservation System 1.0. Affected by this vulnerability is an unknown functionality of the component Administrative Endpoint.

The EmergencyWP – Dead Man's switch & legacy deliverance plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4.2. This is due to missing or incorrect nonce validation on the form_settings_ui (settings save handler, procedural include scope) function. This makes it possible for unauthenticated attackers to modify plugin settings including the minimum access role (altering WordPress role capabilities via add_cap/remove_cap), the data-erasure-on-uninstall flag, life-check timing values, the mandator email address, the confirmation page ID, and date/time formats via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The Passeum Ticketing plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 1.0. This is due to the `get_shop_url()` method returning the `shop_name` setting value without sanitization when it begins with "http", combined with insufficient validation in the `validate_shop_name()` function which only checks for empty values and string type. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary external scripts by setting the `shop_name` to an attacker-controlled URL (e.g., `https://attacker.com`), which causes the plugin to enqueue external JavaScript and CSS from the attacker-controlled domain via `wp_register_script()` and `wp_register_style()`. The injected scripts execute on every frontend page containing any Passeum Ticketing shortcode, affecting all site visitors. Please note that this does not affect single-site installations as administrators already have the `unfiltered_html` capability.

A weakness has been identified in johnhuang316 code-index-mcp up to 2.14.0. Affected is the function is_safe_regex_pattern of the component search_code_advanced. Executing a manipulation of the argument regex can lead to inefficient regular expression complexity. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks. Upgrading to version 2.14.1 is able to address this issue. This patch is called 25bc02fac74051ddae15ce79e952f00211b1ea6b. Upgrading the affected component is recommended.
