CVE-2025-8053 identifies a vulnerability in OpenText Flipper version 3.1.2 related to insufficient granularity of access control, categorized under CWE-1220. This weakness arises when access control mechanisms fail to enforce sufficiently detailed permissions, allowing users with low privileges to perform actions or access backend APIs beyond their intended scope. Specifically, the vulnerability permits a low-privilege authenticated user to interact with backend APIs without the necessary authorization, potentially bypassing security boundaries designed to restrict access to sensitive functions or data. The CVSS 4.0 vector indicates the attack requires local or adjacent network access (AV:A), low attack complexity (AC:L), privileges required (PR:L), and user interaction (UI:A). The vulnerability impacts confidentiality, integrity, and availability at a low level, with no scope change or security requirements bypassed. No known exploits are currently reported, and no patches have been published, indicating the issue is newly disclosed and may require vendor action. The root cause is an incorrect configuration of access control security levels within the Flipper product, which should ideally enforce fine-grained permissions to prevent unauthorized API interactions. This vulnerability highlights the importance of precise access control policies and thorough security testing of backend API endpoints to prevent privilege escalation or unauthorized access.

For European organizations, the impact of CVE-2025-8053 is generally low but should not be overlooked. Organizations using OpenText Flipper 3.1.2 may face unauthorized access to backend APIs by low-privilege users, potentially leading to limited exposure of sensitive data or unauthorized operations. While the vulnerability does not allow full privilege escalation or widespread disruption, it could be leveraged as part of a multi-stage attack chain to gain further access or disrupt services. Sectors such as government, finance, and critical infrastructure that rely on OpenText products for document management or workflow automation might be more sensitive to such unauthorized access. The low CVSS score reflects limited direct impact, but the presence of this vulnerability could undermine trust in access control mechanisms and increase the attack surface. Additionally, the requirement for user interaction and authentication reduces the likelihood of remote exploitation but does not eliminate risk from insider threats or compromised credentials. European organizations should consider this vulnerability in their risk assessments and prioritize remediation accordingly.

1. Conduct a thorough audit of access control configurations within OpenText Flipper 3.1.2, focusing on backend API permissions and security levels. 2. Implement strict role-based access control (RBAC) policies to ensure users have only the minimum necessary privileges. 3. Monitor backend API usage for anomalous or unauthorized access patterns, leveraging logging and alerting mechanisms. 4. Restrict network access to backend APIs to trusted hosts and networks, using firewall rules or network segmentation. 5. Enforce multi-factor authentication (MFA) to reduce the risk of compromised credentials being used to exploit this vulnerability. 6. Engage with OpenText support or security advisories to obtain patches or updates once available. 7. Perform penetration testing and security validation focused on access control enforcement in the affected product version. 8. Educate users about phishing and social engineering risks to minimize the chance of user interaction-based exploitation. 9. Consider upgrading to a later, unaffected version of Flipper if available or applying vendor-recommended mitigations.
