As a WordPress user let me share my experience of using CAPTCHA less and CAPTCHA style Anti-Spam tools on the example of Contact form 7.
Is reCAPTCHA good or bad for Contact form 7?
Contact Form 7 users may prefer Anti-spam by CleanTalk over reCAPTCHA for several reasons, as each solution has its own advantages and disadvantages. Here are some potential reasons why some users prefer Anti-spam by CleanTalk:
Simplicity: Anti-spam by CleanTalk offers a simpler and more user-friendly solution compared to reCAPTCHA. It doesn’t require users to solve puzzles or click checkboxes, which can be seen as an added step that may deter some visitors from submitting forms.
Reduced User Friction: reCAPTCHA can sometimes lead to a less than ideal user experience, especially for those who find it challenging to complete the visual or interactive challenges. Anti-spam by CleanTalk doesn’t require any user interaction, so it doesn’t add any friction to the form submission process.
Invisible to Users: Anti-spam by CleanTalk works invisibly in the background, so users are not aware of its presence. In contrast, reCAPTCHA typically requires users to complete a task to prove they are not a bot.
Accessibility: Some users have accessibility concerns with reCAPTCHA, as it relies on visual verification. Anti-spam by CleanTalk does not present accessibility challenges in the same way, making it a more inclusive solution.
Accuracy: Anti-spam by CleanTalk uses a combination of methods, including machine learning and a vast database of known spam sources, to identify and block spam submissions. This approach can be effective in detecting and preventing spam without relying on user interaction.
Reduced False Positives: reCAPTCHA, while effective at blocking bots, may occasionally generate false positives, blocking legitimate users. Anti-spam by CleanTalk aims to minimize false positives, ensuring that genuine inquiries are not inadvertently marked as spam.
Customization: Users have the ability to customize Anti-spam by CleanTalk settings to meet their specific needs and preferences, tailoring the spam protection to their site’s requirements.
Integration: Anti-spam by CleanTalk is designed to seamlessly integrate with Contact Form 7 and other popular form plugins, making it easy for users to implement spam protection without significant configuration.
Anti-Spam by CleanTalk
It’s important to note that the choice between Anti-spam by CleanTalk and reCAPTCHA may depend on the specific needs and preferences of individual website owners. Some users may prioritize ease of use and a seamless user experience, while others may prioritize the high level of bot detection offered by reCAPTCHA. Ultimately, the choice between these solutions should align with your website’s goals and the user experience you want to provide. Additionally, some users may opt to use both solutions in combination to enhance spam protection further.

September 25, 2023
Registered CVE-2023-4795
Discovery of the Vulnerability
During a thorough evaluation of the Testimonial Slider Shortcode plugin, a significant security vulnerability was uncovered. This vulnerability allows for the execution of Stored Cross-Site Scripting (XSS) attacks through the use of a shortcode within a new post. Intriguingly, this security loophole can be exploited by contributors and users with elevated privileges, potentially leading to unauthorized account access.
Understanding of Stored XSS attack’s
Stored Cross-Site Scripting (XSS) represents a type of security vulnerability where malicious scripts are inserted into a web application and then stored for future execution when other users interact with the affected content. In the context of this vulnerability, attackers can utilize shortcodes to store and subsequently execute malicious JavaScript code.
Exploiting the Stored XSS
Exploiting the Stored XSS vulnerability within the Testimonial Slider Shortcode plugin involves the insertion of malicious code within a shortcode by an attacker with contributor-level privileges or higher. The injected code may include payloads designed to steal user data, impersonate users, or execute actions on behalf of the compromised contributor account. Attackers can create seemingly innocuous posts that, upon viewing, trigger the execution of the malicious script.
POC shortcode:
[tss_item text=»Abelson has been an amazing firm to work with. Lorem changed the company.» name=»JOHN SAMPSON LP» link=’” onmouseover=”alert(/XSS/)”‘/]
This is shortcode which you can add to new post
Despite the requirement for contributor-level privileges, CVE-2023-4795 poses substantial risks. An attacker who successfully exploits this vulnerability can:
Execute arbitrary code within the context of other users’ browsers.
Pilfer sensitive data such as cookies or session information.
Gain unauthorized access to the compromised contributor’s account.
Assume the identity of contributors to carry out nefarious actions on the website.
In a real-world scenario, envision an attacker leveraging this vulnerability to compromise a contributor’s account on a website employing the Testimonial Slider Shortcode plugin. By embedding a malicious shortcode in a seemingly harmless post, they can execute an XSS attack on anyone who views the manipulated content. This could result in unauthorized account access, data breaches, and harm to the website’s reputation.
Recommendations for Improved Security
To mitigate the risks posed by CVE-2023-4795 and enhance the overall security of WordPress websites employing the Testimonial Slider Shortcode plugin, consider the following recommendations:
Plugin updates: Ensure the Testimonial Slider Shortcode plugin is kept up to date, specifically to version 1.1.9 or later, which should contain a patch addressing this vulnerability.
Input validation and sanitization: Developers should implement stringent input validation and data sanitization to prevent the injection of malicious code through shortcodes or other user inputs.
Least privilege principle: Restrict the capabilities and permissions of contributors and other user roles to minimize the potential impact of a compromised account.
Regular security assessments: Routinely conduct security audits and penetration testing to proactively identify and address vulnerabilities.
User education: Educate contributors and administrators about potential security threats and best practices for securely using and managing plugins and shortcodes.
By adhering to these recommendations, website administrators can significantly reduce the risk of Stored XSS attacks and enhance the overall security posture of their WordPress installations, even for vulnerabilities that may require contributor-level privileges.
