CVE-2025-56392 is a security vulnerability classified as an Insecure Direct Object Reference (IDOR) found in the /dashboard/notes endpoint of Syaqui Collegetivity version 1.0.0. IDOR vulnerabilities occur when an application exposes internal implementation objects such as files, database records, or keys directly to users without proper authorization checks. In this case, the vulnerability allows an attacker to impersonate other users by crafting a malicious POST request to the vulnerable endpoint. This enables the attacker to perform arbitrary operations on behalf of the impersonated user, potentially accessing or modifying sensitive data, or executing actions that should be restricted. The vulnerability is present in the application logic of the notes dashboard, which likely manages user-specific notes or data entries. No CVSS score has been assigned yet, and no patches or known exploits in the wild have been reported as of the publication date. The vulnerability was reserved in mid-August 2025 and published at the end of September 2025. The absence of affected version details beyond v1.0.0 suggests this is an early or initial release issue. The lack of authentication or authorization enforcement on the endpoint is the root cause, allowing unauthorized access and operations via crafted requests. This type of vulnerability is critical in multi-user environments where user data isolation is paramount.

For European organizations using Syaqui Collegetivity v1.0.0, this vulnerability poses a significant risk to confidentiality, integrity, and potentially availability of user data. Attackers exploiting this flaw can impersonate legitimate users, gaining unauthorized access to sensitive notes or data, which could include personal, academic, or business-critical information. This could lead to data breaches, unauthorized data manipulation, and loss of trust in the platform. In sectors such as education, research, or collaborative business environments common in Europe, the impact could extend to regulatory non-compliance, especially under GDPR, due to unauthorized access and processing of personal data. The ability to perform arbitrary operations might also allow attackers to escalate privileges or disrupt normal operations, affecting availability. Although no known exploits are reported, the ease of exploitation via crafted POST requests and lack of authentication checks increases the threat level. Organizations relying on this software for collaboration or data management should consider the risk of insider threats or external attackers leveraging this vulnerability to compromise user accounts and data integrity.

Immediate mitigation should focus on implementing strict authorization checks on the /dashboard/notes endpoint to ensure that users can only access or modify their own data. This includes validating user identity against the requested resource and enforcing access control policies server-side. Input validation and request parameter sanitization should be enhanced to prevent manipulation of object references. Organizations should monitor network traffic for suspicious POST requests targeting this endpoint and implement anomaly detection to identify potential exploitation attempts. If possible, disable or restrict access to the vulnerable endpoint until a patch or update is available. Conduct thorough code reviews and penetration testing focused on IDOR vulnerabilities across the application. Additionally, implement multi-factor authentication and session management best practices to reduce the risk of session hijacking or impersonation. Finally, maintain an incident response plan to quickly address any exploitation attempts and notify affected users in compliance with GDPR requirements.
