Security SummaryAI

CVE-2026-1202 is an improper authentication vulnerability (CWE-287) affecting CRMEB versions up to 5.6.3. The flaw resides in the appleLogin function within the file crmeb/app/api/controller/v1/LoginController.php, where manipulation of the openId argument enables attackers to bypass authentication mechanisms. Assigned a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), it was published on 2026-01-20.

Remote attackers require no privileges or user interaction to exploit this vulnerability over the network with low complexity. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, primarily through authentication bypass, potentially granting unauthorized access to the application.

Advisories from VulDB and a public GitHub proof-of-concept detail the issue, noting that an exploit has been released and may be used in attacks. The vendor was contacted early but provided no response, implying no official patches or mitigations are available at this time.
