CVE-2026-51732

Name of the Vulnerable Software and Affected Versions TOTOLINK T6 version 4.1.5cu.748 B20211015

Description Incorrect access control in the delWiFiScheduleCfg() function allows unauthenticated attackers to remove Wi-Fi schedule entries. This is achieved by sending a crafted POST request to the '/cgi-bin/cstecgi.cgi' endpoint.

Recommendations As a temporary workaround, restrict access to the '/cgi-bin/cstecgi.cgi' endpoint or disable the delWiFiScheduleCfg() function until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
