The Copyright Proof WordPress plugin through 4.16 does not sanitise and escape a parameter before outputting it back via an AJAX action available to both unauthenticated and authenticated users, leading to a Reflected Cross-Site Scripting when a specific setting is enabled.

The Featured Image from URL (FIFU) WordPress plugin before 4.0.1 does not validate, sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks when the unfiltered_html capability is disallowed (for example in multisite setup)

The WordPress Popup WordPress plugin through 1.9.3.8 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks when the unfiltered_html capability is disallowed (for example in multisite setup)

The Invitation Based Registrations WordPress plugin through 2.2.84 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks when the unfiltered_html capability is disallowed (for example in multisite setup)

Pandora FMS v7.0NG.760 and below allows an improper access control in Configuration (Credential store) where a user with the role of Operator (Write) could create, delete, view existing keys which are outside the intended role.

The Flexi Quote Rotator WordPress plugin through 0.9.4 does not sanitise and escape its settings, allowing high privilege users such as admin to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.

The Gutenberg plugin through 13.7.3 for WordPress allows stored XSS by the Contributor role via an SVG document to the "Insert from URL" feature. NOTE: the XSS payload does not execute in the context of the WordPress instance's domain; however, analogous attempts by low-privileged users to reference SVG documents are blocked by some similar products, and this behavioral difference might have security relevance to some WordPress site administrators.

### Impact mezzio-swoole applications using Diactoros for their PSR-7 implementation, and which are either not behind a proxy, or can be accessed via untrusted proxies, can potentially have the host, protocol, and/or port of a `Laminas\Diactoros\Uri` instance associated with the incoming server request modified to reflect values from `X-Forwarded-*` headers. Such changes can potentially lead to XSS attacks (if a fully-qualified URL is used in links) and/or URL poisoning. ### Patches 3.7.0, and 4.3.0 and later. The patches present in these versions update the `SwooleServerRequestFactory` to filter out `X-Forwarded-*` headers when creating the initial request. They then by default pass that instance through a `Laminas\Diactoros\ServerRequestFilter\FilterUsingXForwardedHeaders` instance created from the `trustReservedSubnet()` constructor, ensuring that the request only honors the `X-Forwarded-*` headers for private reserved subnets. Users can define the `Laminas\Diactoros\ServerRequ...
