Deeper analysis

CVE-2025-22753 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, affecting the turboSMTP WordPress plugin. The issue impacts all versions of turboSMTP from n/a through 4.6 inclusive and was published on 2025-01-15.

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 it is exploitable over the network with low attack complexity, no privileges required, but user interaction needed, and a changed scope. Remote attackers can exploit it by tricking authenticated or unauthenticated users into interacting with maliciously crafted links or inputs reflected in web pages generated by the plugin, enabling arbitrary script execution in the victim's browser context with low impacts to confidentiality, integrity, and availability.
