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.
CVE-2026-107858 is a high-severity vulnerability in Google Agent Development Kit (ADK) for Java versions before 1.13.0. It involves missing origin validation in WebSockets and permissive cross-domain policies, allowing remote attackers to control a locally running agent via malicious web pages. The vulnerability affects the /run_live WebSocket endpoint and REST API, which accept connections and requests from any origin by default. This enables cross-origin attacks that can trigger tools, stream responses, and manipulate sessions and artifacts. The issue is fixed in version 1.13.0 by enforcing same-origin policies and rejecting DNS-rebinding requests over loopback.
The Anti-Spam by CleanTalk – Spam Protection Without CAPTCHA plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'user_email' parameter in all versions up to, and including, 6.89.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires user registration to be open on the site, and script execution is triggered when an Administrator subsequently runs the plugin's user-spam scan and views the resulting Non-checkable users or Spam users tab — the plugin's own documented workflow.
The Music Store – WordPress eCommerce plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.4.7 via the 'f' parameter parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. Exploitation requires a valid purchase_id token, which any user can obtain by making a single low-cost purchase or receiving a shared download link.
Part-DB-server versions prior to 2.13.3 contain a vulnerability in the password recovery mechanism where the reset link URL is constructed from an unvalidated client-supplied Host header. This allows an unauthenticated attacker to craft a password reset email with a malicious hostname embedding a valid reset token. When the victim clicks the link, the attacker can capture the token and use it to reset the victim's password, including the seeded admin account, resulting in full administrative takeover. The issue is patched in version 2.13.3.
