CVE-2026-36791

Name of the Vulnerable Software and Affected Versions Tenda O3v3 version 1.0.0.5

Description A stack overflow occurs in the formSetCfm() function when processing the save list data parameter. This flaw allows an attacker to trigger a Denial of Service (DoS), which is a condition where the system becomes unavailable to its intended users, by sending a specially crafted HTTP request.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, restrict access to the save list data parameter within the formSetCfm() function to minimize the risk of exploitation.
