CVE-2026-73039 in Streama
Summary
by MITRE • 08/14/2026
streama contains an insecure direct object reference vulnerability in ViewingStatusController that allows authenticated users to read and delete other users' viewing status records. Attackers can enumerate all users' watch progress, delete arbitrary viewing history, and manipulate other users' Continue Watching dashboards by supplying arbitrary primary keys without ownership verification.

The streama application suffers from a critical insecure direct object reference vulnerability within its ViewingStatusController component that fundamentally undermines user privacy and data integrity. This vulnerability exists because the application fails to implement proper access control checks when processing requests related to viewing status records, allowing authenticated users to bypass normal authorization mechanisms. The flaw manifests when the system accepts arbitrary primary key values without verifying whether the requesting user has legitimate ownership or permission rights over the targeted resource.
This technical weakness enables attackers to exploit the application's trust in client-supplied identifiers by manipulating URL parameters or API request payloads containing user-specific primary keys. The vulnerability operates at the application logic level, where the system assumes that authenticated users can access any viewing status record they reference, regardless of ownership relationships. This represents a clear violation of the principle of least privilege and demonstrates poor input validation practices within the controller's processing flow.
The operational impact of this vulnerability extends beyond simple data exposure to encompass active manipulation of user content and dashboard functionality. Attackers can enumerate all users' watch progress by systematically testing different primary key values, effectively creating a comprehensive mapping of user viewing behaviors across the platform. This enumeration capability provides adversaries with detailed insights into user preferences, content consumption patterns, and engagement metrics that could be leveraged for targeted attacks or commercial exploitation.
Furthermore, the vulnerability permits destructive actions including arbitrary deletion of viewing history records, which can result in permanent loss of user data and disruption of service continuity. The manipulation capabilities extend to altering other users' "Continue Watching" dashboards by modifying related viewing status entries, potentially causing confusion and undermining user experience. These actions directly impact user trust in the platform's data integrity and privacy protections.
From a cybersecurity perspective, this vulnerability aligns with CWE-639 (Insecure Direct Object Reference) and represents a significant risk to user privacy as classified under ATT&CK technique T1213.002 (Data from Information Repositories). The flaw demonstrates inadequate authorization controls that should be implemented at the application layer through proper access control checks, session validation, and resource ownership verification before processing any direct object references.
Effective mitigations require implementing robust access control mechanisms within the ViewingStatusController to verify user ownership of requested resources before permitting read or delete operations. This includes validating that the authenticated user possesses legitimate rights to access specific viewing status records through proper authorization checks. The application should also implement defensive programming practices such as parameter validation, input sanitization, and role-based access controls. Additionally, logging and monitoring capabilities should be enhanced to detect suspicious access patterns and unauthorized attempts to manipulate other users' viewing data, providing visibility into potential exploitation attempts and supporting incident response activities.
