Liman MYS Missing Authorization Allows Unauthorized Functionality Access

Missing Authorization vulnerability in HAVELSAN Inc. Liman MYS allows Accessing Functionality Not Properly Constrained by ACLs. This issue affects Liman MYS: before release.Master.1107.

Casky was already ahead

This CVE exploits attack patterns that Casky's 283matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2026-11340 represents a critical authorization bypass in HAVELSAN Inc.'s Liman MYS platform, where access controls fail to properly constrain functionality exposure. This missing authorization vulnerability (CWE-862) allows authenticated or unauthenticated users to access features and data they should not have permission to reach, effectively circumventing the intended role-based access control (RBAC) model. Organizations deploying Liman MYS versions before release.Master.1107 face significant risk, particularly in regulated sectors where data segregation and principle of least privilege are compliance requirements.

Casky's 283 mapped security skills detect the exploitation patterns underlying this vulnerability by analyzing MITRE ATT&CK techniques TA0004 (Privilege Escalation) and TA0006 (Credential Access). Claude AI's extended reasoning identifies unauthorized API calls, function invocations outside user permission scope, and anomalous access patterns to restricted administrative features. Practitioners leveraging Casky would observe findings highlighting: (1) users bypassing UI-level restrictions to directly invoke backend functionality, (2) privilege escalation attempts where standard users execute admin-level operations, (3) ACL enforcement gaps in API endpoints and resource handlers, and (4) audit trail inconsistencies showing unauthorized feature access. These skill correlations enable rapid identification of exploitation attempts and remediation before Liman MYS systems are patched to version .Master.1107 or later.
