600,000 WordPress Sites at Risk: Serious Vulnerability Discovered in WP Fastest Cache

Sites WordPress in Alert: A Vulnerability in WP Fastest Cache Plugin Exposes 600,000 Sites to Risk

Cybersecurity is an issue always warm for those who own and manage a website, especially when it comes to popular platforms such as WordPress. It has recently emerged that WP Fastest Cache, one of the most popular plugins to optimize page loading speed and improve ranking SEO, presents a serious SQL injection vulnerability. This security flaw could allow attackers to gain unauthorized access to the site's database, with potentially devastating consequences.

SQL injection vulnerabilities are among the most insidious cyber threats, as they allow hackers to inject malicious code in SQL queries, allowing access to confidential information or even remote command execution. According to data provided by WordPress.org, WP Fastest Cache is currently used by more than one million sites, but more than 600,000 of these are at risk of attacks due to the use of a vulnerable version Of the plugin.

The WPScan security team of Automatic discovered and catalogued this vulnerability with the code CVE-2023-6063, giving it a severity level of 8.6 out of 10. The critical element is in the "is_user_admin" function of the "WpFastestCacheCreateCache" class, which is supposed to check whether a user is an administrator based on a value extracted from cookies. However, due to improper input handling, attackers can manipulate this check to alter the SQL queries executed by the plugin.

WordPress databases, containing user data, passwords, configurations and other vital information, represent a precious booty for hackers. The imminent release of a proof-of-concept by WPScan on November 27 raises additional concerns, although the not particularly complex nature of the vulnerability suggests that some malicious parties may have already begun to exploit it.

In response to this troubling scenario, the developers of WP Fastest Cache promptly released the 1.2.2 of the plugin, which solves the security problem. Updating the plugin is therefore an action strongly recommended for all users to protect their sites from potential attacks.
