CVE-2025-39478Network attack vector

Script execution via reflected unsanitized input

Published Jun 27, 2025 · Updated Apr 28, 2026

Reflected XSS in Smart IO Labs Smart Notification 10.3 and earlier allows remote attackers to execute script via a crafted request. The plugin fails to sanitize request input and escape it before reflecting the value into a generated WordPress page; the parameter and code locus are undisclosed. Exploitation requires a victim to follow an attacker-controlled link or take a comparable action, after which the script runs in the trusted site origin and can alter page content or access data available to that browser session.
