Insecure Direct Object Reference in School App

School App developed by Zyosoft has an Insecure Direct Object Reference vulnerability, allowing authenticated remote attackers to modify a specific parameter to read and modify other users' data.

Casky was already ahead

This CVE exploits attack patterns that Casky's 261matched skills have been training on — 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-2026-7491 represents a critical Insecure Direct Object Reference (IDOR) vulnerability in Zyosoft's School App that allows authenticated attackers to bypass authorization controls by manipulating object identifiers. By modifying specific parameters in API requests or URLs, attackers can access and alter other users' data without proper permission validation. This vulnerability is particularly concerning in educational environments where student records, grades, personal information, and communication logs are at risk. Any organization deploying this application—including K-12 schools, universities, and educational technology providers—faces exposure of sensitive personally identifiable information (PII) and potential data integrity violations affecting both students and staff.

Casky's 261 matching security skills leverage Claude AI's extended reasoning to detect the attack patterns mapped to MITRE ATT&CK techniques TA0004 (Privilege Escalation) and TA0006 (Credential Access). Practitioners using Casky would identify suspicious patterns such as parameter manipulation attempts in request logs, sequential access to resources belonging to different user accounts, and authorization bypass indicators. The platform's skills would flag requests where authenticated users access data outside their assigned scope—for example, a student attempting to view another student's records by incrementing user IDs in API calls. By correlating these behavioral anomalies with known IDOR exploitation patterns, practitioners gain visibility into both active exploitation attempts and misconfigurations that enable horizontal privilege escalation, enabling rapid detection and containment before widespread unauthorized data access occurs.
