Description

Adversaries may take advantage of security vulnerabilities and inherent functionality in browser software to change content, modify user-behaviors, and intercept information as part of various browser session hijacking techniques.

Security Summary

CVE-2025-24617 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-Site Scripting (XSS) under CWE-79, affecting the AcyMailing SMTP Newsletter WordPress plugin developed by AcyMailing Newsletter Team. The issue impacts all versions prior to 9.11.1, with 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 high severity due to its network accessibility and scope change.

Unauthenticated attackers (PR:N) can exploit this vulnerability over the network (AV:N) with low complexity (AC:L) by tricking users into interacting with a maliciously crafted link or input (UI:R). Successful exploitation leads to reflected XSS, executing arbitrary scripts in the victim's browser within the context of the affected site (S:C), potentially resulting in low-impact confidentiality, integrity, and availability effects, such as session hijacking, data theft, or phishing within the site's privileges.

Patchstack advisories detail the vulnerability in the AcyMailing WordPress plugin and recommend updating to version 9.11.1 or later to mitigate the Reflected XSS issue, as referenced in their database entry.
