What is CVE-2026-24433?

The firmware for Tenda's W30E V2, specifically in versions up to and including V16.01.0.19(5037), is susceptible to a stored cross-site scripting vulnerability. This flaw exists in the user creation functionality, where insufficient input validation allows an attacker to store malicious script content. When administrative users access the affected management pages, this script can be executed, potentially compromising sensitive information or the system’s integrity. Proper remediation, including input validation and sanitization, is crucial to mitigate this vulnerability.
