However, it’s important to note that the debug feature must be enabled for this vulnerability to be a concern, and it is disabled by default.
Summary:
The LiteSpeed Cache plugin for WordPress has a vulnerability in versions up to and including 6.4.1 that exposes sensitive information via publicly accessible log files. This vulnerability has been patched in version 6.5.0.1.
Detailed Overview:
The vulnerability, discovered by Rafie Muhammad from Patchstack, involves the exposure of sensitive information through the publicly accessible debug.log file in versions up to 6.4.1 of the LiteSpeed Cache plugin. This flaw poses a significant risk, as unauthenticated attackers could exploit this to access information such as user cookies, potentially allowing them to take over active sessions and log into WordPress sites without authorization.
The vulnerability’s primary risk lies in the exposure of session data, which could lead to unauthorized access.

- Check for Signs of Vulnerability: If the debug feature was enabled, users should review their logs to check for any exposed sensitive information or unauthorized access attempts. Disabling the debug feature, if not required, is highly recommended.
- Alternate Plugins: Although a patch is available, users might want to explore other caching plugins with similar functionality as a precaution.
- Stay Updated: Ensure that your plugins are always updated to the latest versions to avoid vulnerabilities like this one in the future.
Conclusion:
The prompt response from LiteSpeedTech to patch this vulnerability underscores the importance of keeping plugins up to date. Users are strongly advised to ensure they are running version 6.5.0.1 or later to secure their WordPress installations against potential exploitation.

Detailed Report:
In today’s fast-paced digital world, small business owners often rely on WordPress plugins to keep their websites running smoothly without having to invest too much time in maintenance. However, with convenience comes the responsibility of staying on top of security vulnerabilities that can pose significant risks to your website and, by extension, your business. One such risk has emerged with the discovery of a vulnerability in the LiteSpeed Cache plugin, affecting versions up to and including 6.4.1. This issue could expose sensitive information, leaving your site open to unauthorized access. Fortunately, there are steps you can take to address this vulnerability, and we’re here to guide you through them.
Vulnerability Details
This vulnerability, identified as CVE-2024-44000, exposes sensitive information through the publicly accessible debug.log file in LiteSpeed Cache plugin versions up to 6.4.1. This occurs when the plugin’s debug feature is enabled (disabled by default). The vulnerability allows unauthenticated attackers to access potentially sensitive information, such as user cookies, which could lead to unauthorized access to your site. Once an attacker gains access, they could log in to valid sessions without needing credentials, posing a major security risk.
Risks and Potential Impacts
The primary risk posed by this vulnerability is unauthorized access to your website. Since the debug.log file can store sensitive information like user cookies, an attacker could hijack valid user sessions and log into your site without your knowledge. If your website handles customer data or processes transactions, this vulnerability could expose your business to data breaches, reputational damage, and legal liabilities.
Moreover, even though the debug feature is disabled by default, it’s possible that some users might have enabled it for troubleshooting purposes without realizing the associated risks. The longer your site runs an affected version, the higher the risk of exploitation.
How to Remediate the Vulnerability
To protect your site from this vulnerability, it’s crucial to take the following steps:
- Update to the Latest Version: Ensure that your LiteSpeed Cache plugin is updated to version 6.5.0.1 or later. This version includes the necessary patches to eliminate the vulnerability.
- Check for Signs of Vulnerability: If you have ever enabled the debug feature, review your debug.log files for any signs of unauthorized access or exposed sensitive information. It’s also a good idea to disable the debug feature if it is no longer needed.
- Consider Alternative Plugins: While LiteSpeed Cache has patched this vulnerability, if you’re concerned about ongoing security, you might consider exploring alternative caching plugins that offer similar functionality. However, updating to the latest version is usually the safest route.
- Stay Updated: Regularly check for plugin updates and apply them as soon as possible. WordPress plugins are often the target of cyberattacks, and keeping them updated is your first line of defense.
Previous Vulnerabilities
This is not the first time that LiteSpeed Cache has been exposed to security issues. Since December 2020, the plugin has experienced nine previous vulnerabilities, some of which also involved the exposure of sensitive information or unauthorized access. While each vulnerability was addressed with patches, the pattern underscores the importance of staying vigilant and ensuring your website is always running the latest version of its plugins.
Conclusion
For small business owners who rely on WordPress, maintaining website security can feel overwhelming. However, ignoring these vulnerabilities can lead to serious consequences, including data breaches and unauthorized access. Keeping your plugins up to date is one of the most effective ways to protect your site from such risks.
