Modula Image Gallery Stored Cross-Site Scripting Vulnerability (CVE-2024-9416) — Medium Severity

The Modula Image Gallery plugin is a popular tool for WordPress users to create beautiful image and video galleries. However, a recent discovery highlights a security flaw that every user should know about. This particular issue, identified as CVE-2024-9416, involves a type of attack called Stored Cross-Site Scripting, or XSS, which could allow malicious code to run on your website.

At its core, this vulnerability stems from how the Modula plugin handles certain user-supplied information within its bundled FancyBox JavaScript library. Specifically, versions of FancyBox up to 5.0.36, which were included in older Modula plugin versions, didn’t properly clean up or “sanitize” input, nor did they correctly “escape” output. This means that an attacker could inject harmful scripts into parts of your website. If a visitor then views a page containing this injected script, the script would execute in their browser, potentially leading to unauthorized actions or data theft.

It’s important to note that for this attack to succeed, the attacker would need to be an authenticated user on your WordPress site, with at least a contributor-level role. This limits the immediate risk to external, unauthenticated attackers but still poses a significant threat if an account is compromised or if a malicious insider is present.
