Official Description
A security flaw has been discovered in CRMEB up to 5.6.3. The affected element is the function appleLogin of the file crmeb/app/api/controller/v1/LoginController.php. Performing a manipulation of the argument openId results in improper authentication. The attack is possible to be carried out remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
Risk Analysis
CRMEB contains an authentication bypass vulnerability in the appleLogin function, allowing remote attackers to manipulate the openId argument. This is a critical flaw that grants unauthorized access to the application.
A proof-of-concept exploit has been released to the public, though it is not in the KEV. The vulnerability is remotely exploitable with low complexity.
Apply available patches from the vendor or restrict access to the affected login controller.
Technical Analysis
CVE-2026-1202 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-287): Authentication bypass vulnerabilities allow attackers to access protected resources without valid credentials.
