As of 2024, several WordPress vulnerabilities have been highlighted as critical risks to website security, particularly through known CVEs (Common Vulnerabilities and Exposures). Here’s a summary of the top vulnerabilities:
- Stored Cross-Site Scripting (XSS) in WordPress Core (CVE-2024-4439): This issue stems from improper output sanitization in the WordPress core, specifically in the Avatar block display name. It allows attackers with even limited privileges (like a contributor) to insert malicious scripts, which are then executed whenever users view the page. This vulnerability enables attackers to hijack sessions or collect user data, particularly when users interact with comments or avatars on compromised sites.
- Plugin Source Code Injections (CVE-2024-6297): Several WordPress plugins were compromised by attackers who injected malicious PHP scripts, allowing for unauthorized access to site databases and creating malicious administrator accounts. These scripts exfiltrate sensitive information, posing a severe threat especially to sites relying on popular plugins. The issue remains significant as many compromised plugins have yet to be fully patched.
- WP Statistics Plugin (CVE-2024-2194): This vulnerability affects over 600,000 installations and allows attackers to exploit a stored XSS flaw through URL parameters. When exploited, attackers can inject malicious scripts, potentially gaining admin-level access, which can lead to website defacement or malware installation.
- WP Meta SEO Plugin (CVE-2023-6961): Although discovered in late 2023, this vulnerability remains critical in 2024. It allows stored XSS attacks via the Referer HTTP header. Attackers can use it to hijack administrator credentials, which could be used to manipulate SEO metadata, install backdoors, and perform other harmful activities on the site.
- LiteSpeed Cache Plugin (CVE-2023-40000): This vulnerability, impacting millions of websites, involves XSS flaws that can trigger when administrators access backend pages. If exploited, attackers could leverage admin credentials to alter site content, inject malicious code, or alter caching behaviors, potentially slowing down the website or causing downtime.
The widespread usage of WordPress, with its numerous plugins and themes, makes it highly vulnerable to such attacks, particularly if sites are not regularly updated. Site owners should update to the latest versions of WordPress and plugins, enable security plugins, and perform regular malware scans to mitigate risks. Additionally, implementing input sanitization, enforcing strong Content Security Policies (CSPs), and educating administrators on secure practices can help reduce these vulnerabilities and protect against attacks.
