CWE-79

The Ultimate NoFollow WordPress plugin through 1.4.8 does not sanitise and escape the href attribute of its shortcodes, allowing users with a role as low as contributor to perform Cross-Site Scripting attacks

The Cost Calculator WordPress plugin before 1.6 allows users with a role as low as Contributor to perform Stored Cross-Site Scripting attacks via the Description fields of a Cost Calculator > Price Settings (which gets injected on the edit page as well as any page that embeds the calculator using the shortcode), as well as the Text Preview field of a Project (injected on the edit project page)

The Stylish Cost Calculator WordPress plugin before 7.0.4 does not have any authorisation and CSRF checks on some of its AJAX actions (available to authenticated users), which could allow any authenticated users, such as subscriber to call them, and perform Stored Cross-Site Scripting attacks against logged in admin, as well as frontend users due to the lack of sanitisation and escaping in some parameters

The Custom Content Shortcode WordPress plugin before 4.0.2 does not escape custom fields before outputting them, which could allow Contributor+ (v < 4.0.1) or Admin+ (v < 4.0.2) users to perform Cross-Site Scripting attacks even when the unfiltered_html is disallowed. Please note that such attack is still possible by admin+ in single site blogs by default (but won't be when the unfiltered_html is disallowed)

The GenerateBlocks WordPress plugin before 1.4.0 does not validate the generateblocks/container block’s tagName attribute, which could allow users with a role as low as contributor to perform Cross-Site Scripting attacks.

The WP System Log WordPress plugin before 1.0.21 does not sanitise, validate and escape the IP address retrieved from login requests before outputting them in the admin dashboard, which could allow unauthenticated attacker to perform Cross-Site Scripting attacks against admins viewing the logs.
