Summary
by MITRE • 09/04/2026
A weakness has been identified in jofpin trape 2.0. This affects an unknown part of the file core/user.py. This manipulation of the argument vId/id causes authorization bypass. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The vulnerability identified in jofpin trape version 2.0 represents a critical security flaw located within the core/user.py module, specifically affecting the handling of input arguments related to user identification such as vId or id parameters. This weakness is classified fundamentally as an authorization bypass, which falls under the Common Weakness Enumeration category CWE-287: Improper Authentication and Authorization. The root cause lies in insufficient validation or sanitization logic within the application layer that processes these identifiers. Instead of strictly enforcing access control policies based on verified user credentials or session states, the system appears to rely on the provided identifier value without adequate cross-referencing against authorized permissions. This architectural oversight allows an attacker to manipulate the input parameter to impersonate other users or escalate privileges by simply altering the id field in HTTP requests or API calls directed at the affected endpoint.
The operational impact of this vulnerability is severe due to its remote exploitable nature, meaning that a threat actor can leverage it over a network connection without requiring prior access to the system. Since the exploit code has been made publicly available, the barrier for entry is significantly lowered, enabling less sophisticated attackers or automated scanning tools to compromise the application with minimal effort. Successful exploitation likely results in unauthorized access to sensitive user data, potential modification of account settings, and complete loss of confidentiality and integrity regarding user-specific information stored within the trape platform. In a broader context aligned with the MITRE ATT&CK framework, this behavior corresponds to techniques involving Account Manipulation or Privilege Escalation, where an adversary gains initial access through unauthenticated endpoints and then moves laterally by assuming identities of other users to achieve their objectives.
The fact that the project maintainers were notified early via an issue report but have not yet responded highlights a critical gap in vendor security responsiveness. This delay leaves all instances of jofpin trape 2.0 exposed to active exploitation until a patch is released and deployed by system administrators. In such scenarios, organizations relying on this software must implement compensating controls immediately to mitigate the risk. These measures may include placing the application behind a Web Application Firewall configured with rulesets that detect anomalous patterns in user identification parameters or restricting direct access to the core/user.py endpoints through network segmentation. Additionally, implementing strict input validation and enforcing multi-factor authentication can reduce the likelihood of successful account takeover even if this specific bypass is attempted. Until an official patch from the vendor becomes available, continuous monitoring for suspicious login attempts and unusual data access patterns associated with manipulated user IDs is essential to detect potential breaches in real time.
