EventPrime Missing Authorization in Access Control Configuration

Missing Authorization vulnerability in EventPrime allows Exploiting Incorrectly Configured Access Control Security Levels. This issue affects EventPrime: from n/a through 4.3.2.0.

Casky was already ahead

This CVE exploits attack patterns that Casky's 261matched 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-2026-42669 is a missing authorization vulnerability in EventPrime versions through 4.3.2.0 that exploits incorrectly configured access control security levels. This CWE-862 flaw allows attackers to bypass authorization checks and access resources or perform actions they shouldn't be permitted to execute. Organizations running vulnerable EventPrime instances face immediate risk of unauthorized data access, privilege escalation, and lateral movement within their event management systems. Any user or external attacker who can reach the EventPrime application becomes a potential threat actor, making this vulnerability critical for event management platforms that handle sensitive attendee data, financial transactions, and administrative functions.

Casky.ai's 261 matching security skills leverage Claude's extended reasoning to detect the attack patterns underlying this authorization bypass across MITRE ATT&CK tactics TA0004 (Privilege Escalation) and TA0006 (Credential Access). Practitioners using Casky would observe detection patterns focused on: unauthorized API calls succeeding without proper permission validation, access to administrative functions from non-admin accounts, and configuration manipulation attempts that succeed despite insufficient privileges. The platform's skills would flag anomalous access to protected resources, role-boundary violations, and authentication tokens being used beyond their intended scope. Security teams would see findings highlighting where access control decisions are made but not properly enforced—the classic missing authorization pattern—allowing them to map vulnerable code paths and prioritize remediation of the broken access control logic before exploitation occurs.
