Deeper analysis
CVE-2025-23571 is an Improper Neutralization of Input During Web Page Generation vulnerability, enabling Reflected Cross-site Scripting (XSS) as classified under CWE-79. It affects the Internal Links Generator WordPress plugin (internal-links-generator), impacting all versions from n/a through 3.51 inclusive.
The vulnerability carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating network accessibility, low attack complexity, no required privileges, and user interaction needed, with changed scope and low impacts to confidentiality, integrity, and availability. Remote attackers can exploit it by tricking authenticated users—such as site administrators—into interacting with malicious input, such as a crafted link, to inject and execute arbitrary scripts in the victim's browser context.
