Attackers exploit a Breeze Cache flaw (CVE-2026-3844) to upload files without login. Wordfence researchers detected over 170 attacks.

Threat actors are exploiting a critical flaw, tracked as CVE-2026-3844 (CVSS score of 9.8), in the Breeze Cache WordPress plugin, allowing them to upload files to a server without authentication. The vulnerability has already been used in over 170 attack attempts detected by Wordfence.

Breeze Cache is a free WordPress plugin developed by Cloudways that improves website speed and performance. It offers page and browser caching, file minification, Gzip compression, and CDN integration, helping reduce load times and optimize overall site delivery. The plugin is currently installed on over 400,000 websites.

The security researcher Hung Nguyen (bashu) discovered the vulnerability.

“The Breeze Cache plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the ‘fetch_gravatar_from_remote’ function in all versions up to, and including, 2.4.4. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site’s server which may make remote code execution possible.” reads the report published by Wordfence. “The vulnerability can only be exploited if “Host Files Locally – Gravatars” is enabled, which is disabled by default.”

Wordfence researchers say the flaw stems from missing file-type validation in the ‘fetch_gravatar_from_remote’ function, allowing unauthenticated attackers to upload arbitrary files. This can lead to remote code execution and full site takeover. According to the advisory, the exploitation is only possible if the “Host Files Locally – Gravatars” option is enabled. The issue affects Breeze Cache up to version 2.4.4 and is fixed in version 2.4.5.

Since the vulnerability is actively exploited, Breeze Cache users should update to the latest version immediately or disable the plugin temporarily.

At the time of this writing, Wordfence reported that it had blocked 3,936 attacks targeting this vulnerability in the past 24 hours.

Kali Forms vulnerability

A recently disclosed Kali Forms vulnerability affecting a widely used WordPress plugin has escalated into an active security threat, enabling unauthenticated attackers to achieve Remote Code Execution on affected websites. The flaw impacts Kali Forms, a drag-and-drop form builder with more than 10,000 active installations, and has already been exploited in the wild shortly after public disclosure.  Security researchers reported that the vulnerability was first submitted on March 2, 2026, through a bug bounty program, identifying a critical Remote Code Execution issue in the Kali Forms vulnerability chain. The vendor released a patched version on March 20, 2026, and the issue was simultaneously added to the Wordfence Intelligence database. On the same day, attackers began actively exploiting it on scale. 

Timeline of the Kali Forms Vulnerability in the WordPress Plugin Ecosystem 

The Kali Forms vulnerability followed a rapid disclosure-to-exploitation cycle: 
  • March 2, 2026: Initial submission of the Remote Code Execution flaw via bug bounty reporting. 
  • March 5, 2026: Wordfence Premium, Care, and Response users received firewall protection. 
  • March 20, 2026: Patched version released; vulnerability publicly disclosed; attackers began exploiting the same day. 
  • April 4, 2026: Free Wordfence users received delayed firewall protection. 
  • April 4–10, 2026: Peak exploitation activity observed against the Kali Forms vulnerability. 
The patched release addressed the issue in version 2.4.10 of the WordPress plugin, while all versions up to and including 2.4.9 remained vulnerable. 

Technical Root Cause Behind the Kali Forms Vulnerability

The core of this WordPress plugin flaw lies in how user-supplied form data is processed and stored internally. The vulnerability resides in the form_process flow and the prepare_post_data() function, which incorrectly maps attacker-controlled input into internal placeholder storage without proper validation or allow-list restrictions.  These placeholders are later used in the _save_data() method, where unsafe execution occurs through call_user_func().  A simplified excerpt of the vulnerable logic includes: 
if (isset($this->placeholdered_data['{entryCounter}'])) {    $this->placeholdered_data['{entryCounter}'] =        call_user_func($this->placeholdered_data['{entryCounter}'], $this->post->ID); } 
Because the Kali Forms vulnerability allows attackers to fully control values like {entryCounter} and {thisPermalink}, an unauthenticated user can inject arbitrary PHP function names. These are then executed directly, resulting in Remote Code Execution (RCE) attacks.  Researchers noted that the lack of input restrictions in prepare_post_data() enables overwriting internal placeholders. As a result, attacker-controlled values flow directly into call_user_func(), making exploitation trivial once the request is submitted.  One observed abuse pattern demonstrates authentication bypass attempts using built-in WordPress functions. For example, attackers can assign: 
  • {entryCounter} = wp_set_auth_cookie  
  • formId = 1  
This leads to execution of wp_set_auth_cookie(1), which may log attackers in as the default administrator account if it exists, effectively turning the Kali Forms vulnerability into a full account takeover vector. 

Active Exploitation of the Kali Vulnerability in Real-world Attacks 

Telemetry from security monitoring shows that exploitation began immediately after disclosure. Attackers have been systematically targeting the WordPress plugin using automated requests to admin-ajax.php.  A representative exploit request includes: 
POST /wp-admin/admin-ajax.php HTTP/1.1 Content-Type: application/x-www-form-urlencoded action=kaliforms_form_process& data[formId]=1& data[nonce]=66ddddb2b7& data[entryCounter]=wp_set_auth_cookie 
This confirms how the Remote Code Execution flaw is triggered through manipulated form submission data.  Security systems recorded significant attack volume: 
  • Over 312,200 exploit attempts were blocked targeting the Kali Forms vulnerability. 
  • Heavy targeting was observed immediately after March 20, 2026 disclosure. 
  • Increased spike in activity between April 4 and April 10, 2026. 

Top Attacking IP Addresses Observed 

Threat intelligence identified several IPs responsible for large-scale exploitation attempts: 
  • 209.146.60.26 – over 152,000 blocked requests  
  • 49.156.40.126 – over 50,000  
  • 124.248.183.139 – over 26,000  
  • 202.56.2.126 – over 14,000  
  • 130.12.182.154 – over 11,000  
  • 104.28.160.197 – over 9,000  
  • 1.53.114.181 – over 5,700  
  • 157.15.40.74 – over 3,000  
  • 114.10.99.126 – over 2,500  
  • 83.147.12.83 – over 1,300  
These sources were repeatedly associated with exploitation attempts targeting the Kali Forms vulnerability in the affected WordPress plugin.

An unauthenticated SQL injection flaw (CVE-2026-2413) in the Ally WordPress plugin, used on 400K+ sites, could allow attackers to steal sensitive data.

An unauthenticated SQL injection flaw, tracked as CVE-2026-2413 (CVSS score 7.5), in Ally plugin could allow attackers to steal sensitive data. The offensive security engineer Drew Webber at Acquia discovered the vulnerability on February 4, 2026.

Ally (formerly One Click Accessibility) is a free WordPress plugin that helps creators build accessible websites. It offers an accessibility scanner with AI suggestions, a usability widget for visitors, and an automated accessibility statement generator. The plugin is used on over 400,000 WordPress sites.

The flaw could allow attackers to extract sensitive database data, including password hashes. The issue was responsibly reported by Drew Webber through the Wordfence Bug Bounty Program, earning an $800 bounty. Wordfence notified Elementor on February 13, the vendor acknowledged the report on February 15, and released a patch on February 23, 2026.

Users are urged to update to Ally version 4.1.0 to mitigate the risk.

The vulnerability stems from insecure handling of the subscribers query in Ally. The plugin builds a SQL JOIN query using a page URL parameter without using WordPress’ wpdb->prepare() function, which normally escapes and parameterizes queries.

Although esc_url_raw() is used, it does not prevent SQL injection. This flaw allows attackers to inject malicious SQL. By exploiting it with time-based blind SQL injection, using CASE statements and SLEEP() delays, an attacker could gradually extract sensitive information from the database.

“The Ally – Web Accessibility & Usability plugin for WordPress is vulnerable to SQL Injection via the URL path in all versions up to, and including, 4.0.3.” reads the advisory published by WordFence. “This is due to insufficient escaping on the user-supplied URL parameter in the `get_global_remediations()` method, where it is directly concatenated into an SQL JOIN clause without proper sanitization for SQL context. While `esc_url_raw()` is applied for URL safety, it does not prevent SQL metacharacters (single quotes, parentheses) from being injected. “

The development team addressed the issue by using the wpdb prepare() function in the JOIN statement.

“The vulnerability has been addressed in version 4.1.0 of the plugin.” concludes the advisory. “We encourage WordPress users to verify that their sites are updated to the latest patched version of Ally as soon as possible considering the critical nature of this vulnerability.”
