CVE ID :CVE-2026-8890 Published : May 26, 2026, 7:16 p.m. | 1 hour, 23 minutes ago Description :code100x contains an authentication bypass vulnerability in the Mobile API that allows unauthenticated attackers to impersonate arbitrary users by supplying a crafted JSON payload in the 'g' HTTP header.
