Title
Spam protection, Honeypot, Anti-Spam by CleanTalk <= 6.86 - Unauthenticated Stored Cross-Site Scripting via Comment Content aria-label Placeholder
Summary
The Spam protection, Honeypot, Anti-Spam by CleanTalk plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content aria-label Placeholder in all versions up to, and including, 6.86 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is deliverable via unauthenticated comment submission and executes exclusively for non-logged-in visitors; if comment moderation is enabled, an approving moderator must first publish the comment before the script reaches other users.
Severity

Title
Spam protection, Honeypot, Anti-Spam by CleanTalk <= 6.71 - Authorization Bypass via Reverse DNS (PTR record) Spoofing to Unauthenticated Arbitrary Plugin Installation
Summary
The Spam protection, Anti-Spam, FireWall by CleanTalk plugin for WordPress is vulnerable to unauthorized Arbitrary Plugin Installation due to an authorization bypass via reverse DNS (PTR record) spoofing on the 'checkWithoutToken' function in all versions up to, and including, 6.71. This makes it possible for unauthenticated attackers to install and activate arbitrary plugins which can be leveraged to achieve remote code execution if another vulnerable plugin is installed and activated. Note: This is only exploitable on sites with an invalid API key.

Title
Login Security, FireWall, Malware removal by CleanTalk <= 2.168 - Unauthenticated Stored Cross-Site Scripting via Page URL
Summary
The Login Security, FireWall, Malware removal by CleanTalk plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the page URL in all versions up to, and including, 2.168 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.

Title
Security & Malware scan by CleanTalk <= 2.149 - Unauthenticated Arbitrary File Upload
Summary
The Security & Malware scan by CleanTalk plugin for WordPress is vulnerable to arbitrary file uploads due to the plugin uploading and extracting .zip archives when scanning them for malware through the checkUploadedArchive() function in all versions up to, and including, 2.149. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

Spam protection, Anti-Spam, FireWall by CleanTalk <= 6.44 - Authorization Bypass due to Missing Empty Value Check to Unauthenticated Arbitrary Plugin Installation
Summary
The Spam protection, Anti-Spam, FireWall by CleanTalk plugin for WordPress is vulnerable to unauthorized Arbitrary Plugin Installation due to an missing empty value check on the 'api_key' value in the 'perform' function in all versions up to, and including, 6.44. This makes it possible for unauthenticated attackers to install and activate arbitrary plugins which can be leveraged to achieve remote code execution if another vulnerable plugin is installed and activated.

Title
Security & Malware scan by CleanTalk <= 2.145 - Authorization Bypass via Reverse DNS Spoofing to Unauthenticated SQL Injection
Summary
The Security & Malware scan by CleanTalk plugin for WordPress is vulnerable to unauthorized SQL Injection due to an authorization bypass via reverse DNS spoofing on the checkWithoutToken function in all versions up to, and including, 2.145, as well as insufficient input sanitization and validation. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Security & Malware scan by CleanTalk <= 2.50 - Missing Authorization
Summary
The Security & Malware scan by CleanTalk plugin for WordPress is vulnerable to unauthorized user interaction in versions up to, and including, 2.50. This is due to missing capability checks on several AJAX actions and nonce disclosure in the source page of the administrative dashboard. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to call functions and delete and/or upload files.

Title
Spam protection, Honeypot, Anti-Spam by CleanTalk <= 6.86 - Unauthenticated Stored Cross-Site Scripting via Comment Content aria-label Placeholder
Summary
The Spam protection, Honeypot, Anti-Spam by CleanTalk plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content aria-label Placeholder in all versions up to, and including, 6.86 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is deliverable via unauthenticated comment submission and executes exclusively for non-logged-in visitors; if comment moderation is enabled, an approving moderator must first publish the comment before the script reaches other users.

Title
Spam protection, Honeypot, Anti-Spam by CleanTalk <= 6.71 - Authorization Bypass via Reverse DNS (PTR record) Spoofing to Unauthenticated Arbitrary Plugin Installation
Summary
The Spam protection, Anti-Spam, FireWall by CleanTalk plugin for WordPress is vulnerable to unauthorized Arbitrary Plugin Installation due to an authorization bypass via reverse DNS (PTR record) spoofing on the 'checkWithoutToken' function in all versions up to, and including, 6.71. This makes it possible for unauthenticated attackers to install and activate arbitrary plugins which can be leveraged to achieve remote code execution if another vulnerable plugin is installed and activated. Note: This is only exploitable on sites with an invalid API key.
Severity
9.8 (Critical)
SSVC
Exploitation: none
Automatable: yes
Technical Impact: total

Title
Security & Malware scan by CleanTalk <= 2.149 - Unauthenticated Arbitrary File Upload

Title
Security & Malware scan by CleanTalk <= 2.145 - Authorization Bypass via Reverse DNS Spoofing to Unauthenticated SQL Injection
Summary
The Security & Malware scan by CleanTalk plugin for WordPress is vulnerable to unauthorized SQL Injection due to an authorization bypass via reverse DNS spoofing on the checkWithoutToken function in all versions up to, and including, 2.145, as well as insufficient input sanitization and validation. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

CVE-2020-36698 (GCVE-0-2020-36698)
Vulnerability from cvelistv5 – Published: 2023-10-20 06:35 – Updated: 2026-04-08 16:35

Title
Security & Malware scan by CleanTalk <= 2.50 - Missing Authorization
Summary
The Security & Malware scan by CleanTalk plugin for WordPress is vulnerable to unauthorized user interaction in versions up to, and including, 2.50. This is due to missing capability checks on several AJAX actions and nonce disclosure in the source page of the administrative dashboard. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to call functions and delete and/or upload files.
