Title
W3 Total Cache <= 2.9.3 - Unauthenticated Security Token Exposure via User-Agent Header
Summary
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.

Title
W3 Total Cache <= 2.8.1 Information Exposure via Log Files
Summary
The W3 Total Cache plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 2.8.1 through the publicly exposed debug log file. This makes it possible for unauthenticated attackers to view potentially sensitive information in the exposed log file. For example, the log file may contain nonce values that can be used in further CSRF attacks.
Note: the debug feature must be enabled for this to be a concern, and it is disabled by default.

Title
W3 Total Cache <= 2.8.1 - Authenticated (Subscriber+) Missing Authorization to Server-Side Request Forgery
Summary
The W3 Total Cache plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the is_w3tc_admin_page function in all versions up to, and including, 2.8.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to obtain the plugin's nonce value and perform unauthorized actions, resulting in information disclosure, service plan limits consumption as well as making web requests to arbitrary locations originating from the web application that can be used to query information from internal services, including instance metadata on cloud-based applications.

W3 Total Cache <= 2.7.5 - Sensitive Credentials Stored in Plaintext
Summary
The W3 Total Cache plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 2.7.5 via Google OAuth API secrets stored in plaintext in the publicly visible plugin source. This can allow unauthenticated attackers to impersonate W3 Total Cache and gain access to user account information in successful conditions. This would not impact the WordPress users site in any way.

Title
W3 Total Cache < 2.1.5 - Reflected XSS in Extensions Page (JS Context)
Summary
The W3 Total Cache WordPress plugin before 2.1.5 was affected by a reflected Cross-Site Scripting (XSS) issue within the "extension" parameter in the Extensions dashboard, when the 'Anonymously track usage to improve product quality' setting is enabled, as the parameter is output in a JavaScript context without proper escaping. This could allow an attacker, who can convince an authenticated admin into clicking a link, to run malicious JavaScript within the user's web browser, which could lead to full site compromise.
Severity
No CVSS data available.

Title
W3 Total Cache <= 2.9.3 - Unauthenticated Security Token Exposure via User-Agent Header
Summary
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.

Title
W3 Total Cache <= 2.8.1 Information Exposure via Log Files
Summary
The W3 Total Cache plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 2.8.1 through the publicly exposed debug log file. This makes it possible for unauthenticated attackers to view potentially sensitive information in the exposed log file. For example, the log file may contain nonce values that can be used in further CSRF attacks.
Note: the debug feature must be enabled for this to be a concern, and it is disabled by default.

CVE-2024-12365 (GCVE-0-2024-12365)
Vulnerability from nvd – Published: 2025-01-14 07:05 – Updated: 2026-04-08 16:37

Title
W3 Total Cache <= 2.8.1 - Authenticated (Subscriber+) Missing Authorization to Server-Side Request Forgery
Summary
The W3 Total Cache plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the is_w3tc_admin_page function in all versions up to, and including, 2.8.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to obtain the plugin's nonce value and perform unauthorized actions, resulting in information disclosure, service plan limits consumption as well as making web requests to arbitrary locations originating from the web application that can be used to query information from internal services, including instance metadata on cloud-based applications.

W3 Total Cache <= 2.7.5 - Sensitive Credentials Stored in Plaintext
Summary
The W3 Total Cache plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 2.7.5 via Google OAuth API secrets stored in plaintext in the publicly visible plugin source. This can allow unauthenticated attackers to impersonate W3 Total Cache and gain access to user account information in successful conditions. This would not impact the WordPress users site in any way.

Title
W3 Total Cache < 2.1.5 - Reflected XSS in Extensions Page (JS Context)
Summary
The W3 Total Cache WordPress plugin before 2.1.5 was affected by a reflected Cross-Site Scripting (XSS) issue within the "extension" parameter in the Extensions dashboard, when the 'Anonymously track usage to improve product quality' setting is enabled, as the parameter is output in a JavaScript context without proper escaping. This could allow an attacker, who can convince an authenticated admin into clicking a link, to run malicious JavaScript within the user's web browser, which could lead to full site compromise.
Severity
No CVSS data available.
