CVE-2025-60187 is a vulnerability classified as 'Unrestricted Upload of File with Dangerous Type' in the Atarim visual collaboration platform developed by Vito Peleg. The issue affects all versions up to and including 4.2. This vulnerability allows an unauthenticated attacker to upload files of potentially dangerous types without restriction or validation. The core risk stems from the platform's failure to properly restrict or sanitize file uploads, which can be exploited to introduce malicious files into the system. Although the CVSS base score is 4.8 (medium), reflecting limited confidentiality and integrity impacts and no availability impact, the attack complexity is high, and no privileges or user interaction are required. The vulnerability could allow attackers to execute limited data manipulation or exfiltration by leveraging malicious file uploads, possibly leading to further exploitation if combined with other vulnerabilities. No public exploits or patches are currently available, and the vulnerability was published in November 2025. The lack of authentication requirements increases exposure, but the high complexity and absence of known exploits reduce immediate risk. The vulnerability is relevant to organizations using Atarim for project management and collaboration, especially those handling sensitive or proprietary data.

For European organizations, the impact of CVE-2025-60187 primarily concerns the confidentiality and integrity of data managed within the Atarim platform. Malicious file uploads could lead to unauthorized data access, injection of harmful content, or manipulation of collaboration artifacts. While the vulnerability does not directly affect system availability, the presence of malicious files could facilitate further attacks or data leakage. Organizations in sectors relying heavily on digital collaboration—such as technology, media, and professional services—may face increased risk. The medium severity suggests that while the threat is not critical, it could disrupt workflows and compromise sensitive project information if exploited. Given the unauthenticated nature of the exploit, attackers could attempt to target publicly accessible instances of Atarim, increasing exposure. The lack of known exploits limits immediate impact, but the vulnerability could be leveraged in targeted attacks or combined with other flaws to escalate consequences.

To mitigate CVE-2025-60187, European organizations should implement strict server-side validation of file uploads within Atarim, explicitly restricting allowed file types and rejecting any potentially dangerous extensions. Employing content-type verification and scanning uploaded files for malware can further reduce risk. Network-level controls, such as web application firewalls (WAFs), should be configured to detect and block suspicious upload attempts. Organizations should monitor logs for unusual upload activity and enforce least privilege access to the platform. Applying any future patches or updates from Vito Peleg promptly is critical once available. Additionally, isolating the Atarim environment and limiting its exposure to trusted networks can reduce attack surface. User education about the risks of uploading untrusted files and regular security assessments of the collaboration platform will enhance overall defense.
