EmbedPress vulnerabilities

The EmbedPress WordPress plugin before version 4.6.7 does not sanitise and escape one of its Elementor widget settings before outputting it into an HTML attribute, which could allow users with the Contributor role or above to inject arbitrary web scripts that execute when the affected content is viewed.

The EmbedPress plugin for WordPress up to version 4.6.6 is vulnerable to stored XSS via the 'slidesShow' block attribute. Authenticated attackers with contributor-level access can inject scripts that execute when a user visits the page.

The EmbedPress WordPress plugin before 4.6.7 does not escape one of its block attributes before outputting it inside an HTML attribute, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks against higher privileged users viewing the post.

The EmbedPress WordPress plugin before version 4.6.4 does not have proper authorization on a public review-loading action, allowing unauthenticated users to force the site to make repeated billable third-party API requests using the site's own configured API key, and to create an unbounded number of attacker-controlled rows in the database.

The EmbedPress WordPress plugin before version 4.6.4 does not perform a sufficient authorization check on one of its Google Reviews REST API routes, allowing users with the Contributor role and above to modify a site-wide store, deleting entries an administrator configured and injecting their own, which are rendered publicly across the site.

The EmbedPress WordPress plugin before version 4.6.4 does not properly restrict access to one of its Google Reviews REST routes, allowing any authenticated user with contributor-level access or above to read the site administrator's email address, a value WordPress core withholds from that role.

Unauthenticated Cross Site Scripting (XSS) in EmbedPress versions up to and including 4.5.6.

The EmbedPress WordPress plugin before 4.6.1 does not validate user-supplied URLs before making server-side requests through unauthenticated endpoints. This allows unauthenticated attackers to induce the site to send HTTP requests to internal hosts and services that WordPress core URL validation does not cover (a blind Server-Side Request Forgery).

Versions of EmbedPress up to 4.5.2 are vulnerable to unauthorized access to sensitive data.

The EmbedPress plugin for WordPress up to version 4.5.3 is vulnerable to Stored Cross-Site Scripting via the block 'url' attribute. Authenticated attackers with contributor-level access can inject arbitrary scripts that execute whenever a user visits the page.
