Security Summary

CVE-2025-23826 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Stored Cross-site Scripting (XSS) under CWE-79, in the WordPress plugin Stop Comment Spam by pedjas (stop-comment-spam). The issue affects all versions from n/a through 0.5.3.

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), the vulnerability can be exploited over the network with low attack complexity by unauthenticated attackers (PR:N), though it requires user interaction such as an administrator viewing a maliciously crafted page. Successful exploitation changes scope (S:C) via CSRF-to-stored XSS, enabling limited impacts on confidentiality, integrity, and availability, such as script execution in the victim's browser context.
