CVE-2025-48326 is a Missing Authorization vulnerability (CWE-862) identified in Acclectic Media Organizer, a media management software product by Acclectic Media. The vulnerability arises due to incorrectly configured access control security levels, allowing users with limited privileges (PR:L - privileges required: low) to perform unauthorized actions that should be restricted. The CVSS 3.1 base score is 6.5, indicating a medium severity level. The attack vector is network-based (AV:N), requiring no user interaction (UI:N), and the scope remains unchanged (S:U). Although confidentiality impact is none (C:N), the vulnerability can cause a high impact on integrity (I:H), meaning unauthorized modification or manipulation of data or system state is possible. Availability is not affected (A:N). The affected versions are not specifically enumerated but include all versions up to 1.4. No patches or known exploits are currently reported. This vulnerability could allow an attacker with low-level privileges to escalate their capabilities or perform unauthorized operations within the Acclectic Media Organizer environment, potentially compromising the integrity of media assets or metadata managed by the software.

For European organizations using Acclectic Media Organizer, this vulnerability poses a significant risk to the integrity of their media management workflows. Unauthorized modification of media files, metadata, or organizational data could disrupt business operations, lead to data corruption, or cause loss of trust in digital asset management processes. Organizations in media, broadcasting, marketing, and content production sectors are particularly vulnerable as they rely heavily on accurate and secure media asset management. The lack of confidentiality impact reduces the risk of data leakage, but the integrity compromise can still result in operational disruptions and reputational damage. Since exploitation requires only low-level privileges and no user interaction, insider threats or compromised accounts could be leveraged to exploit this vulnerability. The absence of known exploits in the wild suggests a window of opportunity for proactive mitigation before widespread attacks occur.

Given the absence of official patches, European organizations should implement compensating controls immediately. These include: 1) Restricting user privileges strictly to the minimum necessary, ensuring that only trusted users have access to the Acclectic Media Organizer with elevated permissions; 2) Implementing network segmentation and access controls to limit exposure of the Acclectic Media Organizer to trusted internal networks only; 3) Monitoring and logging all access and modification activities within the software to detect anomalous or unauthorized actions promptly; 4) Conducting regular audits of user roles and permissions within the application to identify and remediate misconfigurations; 5) If possible, deploying web application firewalls (WAFs) or intrusion detection/prevention systems (IDS/IPS) tuned to detect suspicious requests targeting the media organizer; 6) Engaging with the vendor for updates or patches and planning timely application once available; 7) Educating users about the risks of privilege misuse and enforcing strong authentication mechanisms to reduce the risk of account compromise.
