Deeper analysis
CVE-2025-23580 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the BizLibrary WordPress plugin by Matthew BizLibrary. This issue affects BizLibrary versions from n/a through 1.1 inclusive. The vulnerability was published on 2025-01-21 and 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).
An unauthenticated attacker (PR:N) can exploit this vulnerability over the network (AV:N) with low attack complexity (AC:L), though it requires user interaction (UI:R), such as clicking a malicious link. Exploitation reflects attacker-controlled input into the web page, enabling script execution in the victim's browser with a changed scope (S:C). This can result in low-level impacts on confidentiality, integrity, and availability, such as session hijacking or data theft within the site's context.
