Deeper analysis
CVE-2025-10855 is an Authorization Bypass Through User-Controlled Key vulnerability (CWE-639) in Teknoera from Solvera Software Services Trade Inc. The flaw allows Exploitation of Trusted Identifiers and affects Teknoera versions through 01102025. It has a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high severity due to network accessibility, low attack complexity, and no prerequisite privileges or user interaction.
Remote attackers require no authentication to exploit this vulnerability over the network. Successful exploitation bypasses authorization controls via user-controlled keys, resulting in high-impact unauthorized access to confidential data without disrupting integrity or availability.
