The vulnerability CVE-2025-28871 in jwpegram's Block Spam By Math Reloaded plugin allows stored cross-site scripting due to improper input neutralization during web page generation. This enables an attacker with high privileges and requiring user interaction to inject malicious scripts that can impact confidentiality, integrity, and availability to a limited extent. The issue affects versions up to 2.2.4. No patch or vendor advisory is currently available to confirm remediation status.

Successful exploitation could allow an attacker with high privileges to inject and store malicious scripts that execute in the context of other users, potentially leading to limited confidentiality, integrity, and availability impacts. The CVSS vector indicates network attack vector, low attack complexity, high privileges required, user interaction required, and a scope change, with partial impacts on confidentiality, integrity, and availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict high-privilege user access and carefully validate and sanitize inputs where possible to reduce risk.
