This vulnerability (CVE-2026-11763) in GisLab Laboratory Management System allows an attacker with low privileges to bypass authorization controls by manipulating user-controlled keys, exploiting trusted identifiers. This could lead to unauthorized access to sensitive information, as the confidentiality impact is high, while integrity and availability are not affected. The affected version explicitly identified is 1.4.03. No official patch or remediation guidance is currently provided by the vendor, and no known exploits are reported in the wild.

An attacker with network access and low privileges can bypass authorization mechanisms, potentially gaining unauthorized access to sensitive data. The confidentiality impact is high, but integrity and availability remain unaffected. This could lead to information disclosure within the affected system.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to trusted users and monitor for suspicious activity related to authorization bypass attempts. Avoid relying on user-controlled keys for authorization decisions.
