CVE-2025-22595

CVE-2025-22595 is an Improper Neutralization of Input During Web Page Generation vulnerability, manifesting as a Reflected Cross-site Scripting (XSS) issue under CWE-79. It affects the Mailing Group Listserv WordPress plugin (wp-mailing-group) developed by Yamna Khawaja, impacting all versions from n/a through 2.0.9 inclusive. The vulnerability was published on 2025-01-09.

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 such as clicking a malicious link. Remote attackers can exploit it by crafting inputs that are reflected unsanitized in web pages, executing arbitrary scripts in the context of a victim's browser. This enables low-impact theft of sensitive data like session cookies, minor data manipulation, or limited denial of service, with scope changes allowing cross-origin influence.
