What is CVE-2026-16535?

The Link Library plugin for WordPress versions prior to 7.9.4 is susceptible to reflected cross-site scripting (XSS). The plugin fails to properly sanitize and escape a specific parameter that is echoed back in HTTP responses. This oversight allows unauthenticated attackers to exploit the vulnerability and potentially execute arbitrary JavaScript code in the context of the user's session, compromising user data and site integrity if users are manipulated into executing crafted requests.

Affected Version(s)

Link Library 0 < 7.9.4

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
