Co. BAPSİS before version 202604152042, allowing exploitation of trusted identifiers through a user-controlled key.CVE-2026-6001 describes an authorization bypass vulnerability affecting ABIS Technology Ltd. Co.’s BAPSİS product. The vulnerability, reported by the Computer Emergency Response Team of the Republic of Turkey, stems from a user-controlled key that allows for the exploitation of trusted identifiers. This flaw affects BAPSİS versions prior to 202604152042. Successful exploitation could allow an attacker to bypass intended authorization controls, potentially gaining unauthorized access to sensitive data or functionality. Defenders should prioritize patching vulnerable BAPSİS instances to mitigate this risk.

Attack Chain

  1. An attacker identifies a BAPSİS instance running a version prior to 202604152042.
  2. The attacker crafts a malicious request, exploiting the user-controlled key vulnerability.
  3. The malicious request is sent to the BAPSİS server.
  4. BAPSİS processes the request, improperly validating the user-controlled key.
  5. The attacker gains unauthorized access due to the bypassed authorization.
  6. The attacker exploits trusted identifiers to perform unauthorized actions.
  7. The attacker may then escalate privileges.

Impact

Successful exploitation of CVE-2026-6001 allows attackers to bypass authorization controls within ABIS Technology’s BAPSİS, potentially leading to unauthorized access to sensitive information, modification of critical data, or execution of privileged functions. The vulnerability has a CVSS v3.1 score of 8.8, indicating a high level of risk. The impact of this vulnerability could be severe, especially for organizations relying on BAPSİS for critical operations.

Recommendation

  • Upgrade BAPSİS to version 202604152042 or later to remediate CVE-2026-6001.
  • Monitor web server logs for suspicious requests targeting BAPSİS that may indicate exploitation attempts. Deploy the provided Sigma rule targeting CWE-639 (Authorization Bypass Through User-Controlled Key).
