The Photo Gallery by 10Web WordPress plugin before 1.8.49 does not escape a shortcode attribute that sets a gallery watermark image before rendering it into an HTML image attribute, and decodes percent-encoded characters in the value, allowing users with Contributor-level access and above to perform Stored Cross-Site Scripting that executes in the browser of any user, including an administrator, who views the published gallery.

The Defender Security WordPress plugin before 6.4.1 does not verify that the client IP address it derives for its firewall and lockout decisions actually originates from a trusted source, trusting a user-supplied value by default, allowing unauthenticated attackers to spoof their IP address and evade IP-based protections such as login lockout and IP banning, impersonate an allowlisted address, and poison the Defender Security WordPress plugin before 6.4.1's activity logs.

The Defender Security WordPress plugin before 6.4.1 does not limit the number of failed two-factor authentication attempts in its default configuration, allowing an attacker who already knows a victim's password to brute-force the one-time code and defeat the second authentication factor.

The ProfilePress WordPress plugin before 4.17.4 does not check that a membership plan is still active when checkout is used to change an existing subscription, allowing subscribers holding any subscription of their own to subscribe to plans the site owner has deactivated, including free plans that grant a user role.

The Schema & Structured Data for WP & AMP WordPress plugin before 1.70 does not verify that a post is publicly viewable before returning its approved comments through the review feature, allowing unauthenticated attackers to read approved comments on private, draft and password-protected posts, and to retrieve approved comments site-wide.

The Advanced Product Fields (Product Addons) for WooCommerce WordPress plugin from 1.6.22 to 1.7.3 does not validate that a submitted value for a required paid product option matches one of the configured choices, only that it is not empty, allowing unauthenticated users to add a product to the cart and complete an order while skipping the required option's surcharge and paying only the base product price.

The Post Duplicator WordPress plugin before 3.0.18 does not validate the capabilities assigned to roles through its permissions settings, allowing a site administrator on a multisite network who is not a Super Admin to grant any role arbitrary capabilities, including the network-management capabilities reserved to the Super Admin.

The Post Duplicator WordPress plugin before 3.0.18 does not restrict settings saves to its own options, allowing a site administrator on a multisite network who is not a Super Admin to overwrite arbitrary options of their site, including the role definitions, and so grant themselves network-management capabilities.

The All-in-One Video Gallery WordPress plugin before 5.1.1 does not check whether a video is password protected before serving it through its standalone player page and its download link, allowing unauthenticated visitors to obtain the media source of password-protected videos, such as unlisted YouTube or Vimeo links and external file URLs.

The FV Flowplayer Video Player WordPress plugin before 7.5.57.7212 does not perform any authorization check on an AJAX action that carries out a site-wide content rewrite, so any authenticated user, including subscriber-level, can trigger a bulk modification of posts they should not be able to edit.

The MC4WP: Mailchimp for WordPress plugin before 4.15.0 does not validate that the Mailchimp audience a sign-up form or bundled integration subscribes a visitor to matches the audience configured by the site owner, allowing unauthenticated visitors to subscribe arbitrary email addresses to any other audience in the site's connected Mailchimp account.

The All-in-One Video Gallery WordPress plugin before 5.1.0 does not escape a video's stored thumbnail URL before outputting it in the admin video list, and does not sanitise that value when it is written outside its own editor, allowing users with a role as low as Subscriber to perform Stored Cross-Site Scripting attacks against administrators.

The Subscriptions for WooCommerce WordPress plugin before 2.1.1 only enforces its membership content restrictions on standard front-end page views, allowing unauthenticated users to read the full contents of restricted posts and pages through other routes that render the same content.

The FV Flowplayer Video Player WordPress plugin before 7.5.56.7212 does not sanitize and escape a user-supplied value before outputting it in a page, which could allow users with the Contributor role and above to inject arbitrary web scripts that execute when a higher-privileged user views the affected page.

The FV Flowplayer Video Player WordPress plugin before 7.5.56.7212 does not perform authorization or CSRF checks on several of its cloud storage media browser handlers, allowing any authenticated user with minimal permissions (such as Subscriber) to disclose the configuration and stored file listings of the site's connected cloud storage accounts.

An issue exists where the plugin fails to properly sanitize the staging destination folder provided to the `staging-start` handler. While the `writability-check` handler uses a correct filename sanitizer, the `staging-start` handler only applies a generic text filter. This allows an authenticated administrator to use path traversal sequences—a technique used to access files and directories outside the intended folder—to write copied site files outside the WordPress installation directory.

Insufficient validation of user-supplied paths allows authenticated users with administrator-level access to perform path traversal. This occurs when the plugin fails to properly validate a backup storage directory path before using it to create directories and write files, enabling the creation of files and directories outside the intended backup location.

An issue exists where the plugin fails to verify if a submitted snapshot identifier corresponds to a snapshot created by the plugin before using it as a database table-name prefix in DROP TABLE queries. An authenticated administrator can exploit this by providing the site's table prefix or any other string, allowing them to drop arbitrary database tables, including core WordPress tables, which leads to complete site destruction.

Insufficient input sanitization and output escaping in a shortcode attribute allow authenticated users with the Contributor role and above to perform Stored Cross-Site Scripting attacks. This occurs when the plugin fails to escape a shortcode attribute before outputting it within the attributes of generated links, enabling the injection of arbitrary web scripts that execute when a user accesses the affected page.

An issue exists where the plugin fails to verify if the requesting user has the necessary permissions to view a post before disclosing its assigned taxonomy terms. This occurs due to a missing capability check in a function, allowing any authenticated user, including those with subscriber-level access, to discover term assignments for private posts and attachments.
