Threat database

The weForms WordPress plugin up to version 1.6.28 contains a path traversal vulnerability that allows unauthenticated attackers to delete arbitrary media files on the server. This occurs due to insufficient file path validation in the weforms_delete_entry_attachments function. Exploitation requires an administrator to permanently delete a specially crafted form entry, which an attacker can induce via social engineering. The vulnerability has a medium severity rating with a CVSS score of 5.4.

The Post and Page Builder by BoldGrid – Visual Drag and Drop Editor WordPress plugin is affected by a stored cross-site scripting (XSS) vulnerability in the Table Designer 'data-label' attribute. This vulnerability exists in all versions up to and including 1.27.13 and allows authenticated users with Contributor-level access or higher to inject malicious scripts that execute when other users view the affected pages. The CVSS score is 6.4, indicating a medium severity risk.

The W3 Total Cache WordPress plugin versions up to and including 2.10.6 contain a stored cross-site scripting (XSS) vulnerability. This flaw arises from improper input sanitization and output escaping in the handling of comment content when the 'Remove query strings from static resources' option is enabled. An unauthenticated attacker can inject malicious scripts that execute in the context of users visiting the affected pages. The vulnerability requires a specific configuration setting to be enabled to be exploitable.

Unauthenticated Cross Site Scripting (XSS) in Post and Page Builder by BoldGrid <= 1.27.14 versions.

Unauthenticated Insecure Direct Object References (IDOR) in Client Invoicing by Sprout Invoices <= 20.8.17 versions.

The W3 Total Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content via LazyLoad Background Mutator in all versions up to, and including, 2.10.5 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. This requires the "Lazy Load Images" feature with "Process background images" to be enabled, and the malicious comment to be approved by a moderator before execution is triggered.

The W3 Total Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Author Name in all versions up to, and including, 2.10.3 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. This vulnerability is only exploitable when the Lazy Load Images feature of W3 Total Cache is enabled, as the unsafe re-emission occurs exclusively within the LazyLoad mutator's img tag rewriting step.

CVE-2026-66708 is a high severity vulnerability in BoldGrid Total Upkeep versions up to and including 1.17.2. It involves missing authorization controls allowing unauthenticated users to perform actions that should be restricted. The vulnerability is classified as CWE-862 (Missing Authorization). No official patch or remediation guidance is currently available from the vendor.

CVE-2026-66695 is a medium severity unauthenticated path traversal vulnerability affecting BoldGrid's W3 Total Cache plugin versions up to and including 2.10.2. The flaw allows an attacker to perform path traversal using sequences like '.../...//', potentially leading to limited integrity and availability impacts. No official patch or remediation guidance has been provided yet, and no known exploits are reported in the wild.

Unauthenticated Cross Site Scripting (XSS) in Sprout Clients <= 3.2.3 versions.

Missing Authorization vulnerability in BoldGrid Client Invoicing by Sprout Invoices sprout-invoices allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Client Invoicing by Sprout Invoices: from n/a through <= 20.8.13.

The W3 Total Cache plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.9.4 via the setupSources function. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. Exploitation requires enabling manual minify mode and supplying a manual-format minify filename so that the hash is empty and the f_array[] entries are not overwritten before reaching setupSources().

Unauthenticated Arbitrary Code Execution in W3 Total Cache <= 2.9.4 versions.

CVE-2026-39595 is a medium severity vulnerability in BoldGrid's W3 Total Cache plugin versions up to and including 2.9.1. It involves broken access control, specifically missing authorization checks, which can lead to limited confidentiality, integrity, and availability impacts. No official patch or remediation guidance is currently available from the vendor.

The Total Upkeep – WordPress Backup Plugin plus Restore & Migrate by BoldGrid plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'wp_ajax_cli_cancel' function in all versions up to, and including, 1.17.1. This makes it possible for unauthenticated attackers to cancel a pending rollback, potentially preventing a WordPress installation from automatically reverting a failed update.

Missing Authorization vulnerability in BoldGrid Client Invoicing by Sprout Invoices sprout-invoices allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Client Invoicing by Sprout Invoices: from n/a through <= 20.8.10.

The W3 Total Cache plugin for WordPress is vulnerable to information exposure in all versions up to, and including, 2.9.3. This is due to the plugin bypassing its entire output buffering and processing pipeline when the request's User-Agent header contains "W3 Total Cache", which causes raw mfunc/mclude dynamic fragment HTML comments — including the W3TC_DYNAMIC_SECURITY security token — to be rendered in the page source. This makes it possible for unauthenticated attackers to discover the value of the W3TC_DYNAMIC_SECURITY constant by sending a crafted User-Agent header to any page that contains developer-placed dynamic fragment tags, granted the site has the fragment caching feature enabled. With the leaked W3TC_DYNAMIC_SECURITY token, an attacker can craft valid mfunc tags to execute arbitrary PHP code on the server, achieving remote code execution.

Deserialization of Untrusted Data vulnerability in BoldGrid weForms weforms allows Object Injection.This issue affects weForms: from n/a through <= 1.6.26.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in BoldGrid Sprout Clients sprout-clients allows Stored XSS.This issue affects Sprout Clients: from n/a through <= 3.2.2.

Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in BoldGrid Client Invoicing by Sprout Invoices sprout-invoices allows PHP Local File Inclusion.This issue affects Client Invoicing by Sprout Invoices: from n/a through <= 20.8.9.
