The Advanced Custom Fields: Extended WordPress plugin before 0.9.2.8, Advanced Custom Fields: Extended PRO WordPress plugin before 0.9.2.8 does not perform any capability check when updating a post through one of its front-end form actions, allowing unauthenticated visitors to overwrite arbitrary posts, including the ones in which the site stores its own field definitions, which in turn leads to arbitrary code execution on the server. Exploitation requires the site to publish a form whose post-update action maps both its target and its content to visitor-submitted values.
The Advanced Custom Fields: Extended WordPress plugin before 0.9.2.8, Advanced Custom Fields: Extended PRO WordPress plugin before 0.9.2.8 does not validate or escape some of its form shortcode attributes, which can be pointed at values taken from the visitor's own request and are then output without escaping, allowing users with a role as low as contributor to have arbitrary script run in the browser of anyone led to open a crafted link or page, including a logged-in administrator.
This is an incomplete fix for CVE-2023-5292, whose deny-list covers only the three HTML wrapper attributes.
The Advanced Custom Fields: Extended WordPress plugin before 0.9.2.8, Advanced Custom Fields: Extended PRO WordPress plugin before 0.9.2.8 does not verify that the requester is authorised to edit the targeted user account in the update-user action of its front-end Forms module, performing that check only when the target account holds an administrator role, which allows unauthenticated visitors to overwrite any non-administrator account's credentials and obtain a session for that account. Exploitation requires the site to publish a form whose user-update action maps its target to a visitor-submitted value rather than to the default current user.
The LiteSpeed Cache WordPress plugin before 7.9.2 does not perform a capability check on its admin-notice dismissal handler, and the nonce it relies on is not bound to the specific notice being dismissed, so on sites in certain configurations a low-privileged authenticated user (Subscriber) can dismiss administrative notices the LiteSpeed Cache WordPress plugin before 7.9.2 marks as non-dismissible, including a warning that sensitive files may be publicly accessible.
The LiteSpeed Cache WordPress plugin before 7.9.2 does not limit one of its HTML optimization routines to stylesheet content, so it can delete the markup that closes an attribute in the rendered page, and combined with unescaped comment author output this allows unauthenticated users whose comments are published to inject event-handler attributes that run JavaScript in the browser of any visitor, including a logged-in administrator, viewing front-end pages while the optimization is enabled.
The LiteSpeed Cache WordPress plugin before 7.9.2 does not restrict one of its HTML rewriting routines to stylesheet content, so it removes a quote that terminates an attribute in the rendered page, and combined with unescaped comment author output this allows unauthenticated users whose comment is published to inject attributes that execute JavaScript in the browser of any visitor, including a logged-in administrator, who views front-end pages while the affected option is enabled.
The Depicter — Popup & Slider Builder WordPress plugin before 4.8.2 does not properly validate uploaded files in its editor media-upload endpoint, checking only the client-supplied MIME type and a case-sensitive block of the .php extension, which allows users with the Editor role and above to upload files with other active extensions into the public uploads directory, leading to stored script execution in the site origin and, depending on the server's handler mapping, to code execution.
The Popup Builder WordPress plugin versions before 4.4.6 contain a vulnerability where authorization checks are not performed before trashing popup content during a maintenance routine triggered by unauthenticated requests. This flaw allows unauthenticated attackers to move popups into the Trash and overwrite their preview data.
The Download Monitor WordPress plugin before 5.3.5 does not correctly restrict management of the list of filesystem locations it may serve files from to network administrators on multisite, allowing a subsite administrator who is not trusted at the network level to approve arbitrary locations and have the Download Monitor WordPress plugin before 5.3.5 serve readable files from outside the uploads directory, including files belonging to other subsites, to unauthenticated visitors; single-site installations are unaffected.
The User Profile Builder WordPress plugin versions before 4.0.5 contain an authorization bypass vulnerability. This flaw allows an Administrator of a Multisite subsite to edit any user's account email via the front-end Edit Profile form without proper authorization checks. Exploiting this, an attacker can change the email of a Network Super Admin account and potentially take over that account through the password reset process.
The User Profile Builder WordPress plugin versions before 4.0.5 contain a vulnerability where one shortcode attribute is not properly sanitized and escaped before being output in a redirect message. This flaw allows users with contributor-level permissions to perform stored cross-site scripting (XSS) attacks against users with higher privileges who submit the affected form.
The Speed Optimizer WordPress plugin before 7.8.5 does not verify network-level privilege before applying an option change to the whole multisite network, nor restrict which option may be changed, allowing a site administrator who is not a Super Admin to create or overwrite network-wide options.
The Speed Optimizer WordPress plugin before 7.8.5 does not sanitise or escape some of its settings before outputting them in the head of front-end pages, which could allow high-privilege users such as admins to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in a multisite setup).
The Essential Addons for Elementor WordPress plugin before 6.8.7 does not verify that an administrator may manage the specific user accounts targeted by its login-approval feature, checking only a site-level capability, which on WordPress Multisite could allow a subsite administrator to change the approval and login state of accounts belonging to other sites on the network.
The Essential Addons for Elementor WordPress plugin before 6.8.7 does not validate the HTML tag setting of some of its widgets before using it to build markup, which could allow users with the author role and above to inject iframe and form elements into published pages.
The Otter Blocks WordPress plugin versions before 3.2.8 contains a vulnerability where a pattern used to rewrite dynamic-content tokens is not properly bounded. This flaw allows the pattern to consume the quote closing an HTML attribute and incorporate adjacent unescaped data as new attributes. As a result, unauthenticated users can perform stored Cross-Site Scripting (XSS) attacks that execute in the browsers of any visitors viewing the affected page, including logged-in administrators.
The Otter Blocks WordPress plugin before 3.2.8 does not enforce its block visibility conditions when a published post is rendered through the WordPress REST API, allowing unauthenticated users to read block content that the site owner restricted to specific roles, logged-in users, the post author, categories or tags, or (on the Pro tier) Stripe purchasers.
The Otter Blocks WordPress plugin versions before 3.2.8 improperly handle access control for post data via a REST API endpoint. It treats any post with published status as publicly readable, allowing unauthenticated users to access manual excerpts of password-protected posts, content and titles of non-public post types, and on WooCommerce sites, coupon codes and their descriptions. This vulnerability can lead to unauthorized information disclosure.
The Otter Blocks WordPress plugin versions before 3.2.8 contain a vulnerability where user-supplied block styling values are not properly sanitized and escaped before being written into inline stylesheets. This flaw allows users with contributor-level access or higher to inject arbitrary web scripts that execute when any visitor, including administrators, views the affected post. The vulnerability is identified as CVE-2026-109933 and has a CVSS score of 6.8, indicating a medium severity level.
