CVE-2025-6282 is a path traversal vulnerability identified in the xlang-ai OpenAgents product, specifically affecting the create_upload_file function within the backend/api/file.py file. This vulnerability allows an attacker with limited privileges (low privileges) and remote access (attack vector: adjacent network) to manipulate file paths during the upload process, potentially enabling unauthorized access or modification of files outside the intended directory. The vulnerability does not require user interaction and does not require authentication, but it does require the attacker to have some level of access to the network where the service is reachable. The vulnerability has been publicly disclosed, but no patches or updated versions have been released or planned, as indicated by the automatic closure of the related GitHub issue with a "not planned" label. The product uses continuous delivery with rolling releases, complicating version tracking and patch management. The CVSS 4.0 base score is 5.1 (medium severity), reflecting the limited scope and complexity of exploitation, as well as the partial impact on confidentiality, integrity, and availability. The vulnerability could allow attackers to read or write arbitrary files on the server, potentially leading to information disclosure, data tampering, or service disruption, depending on the server configuration and file system permissions. However, the exploitability is limited by the requirement of network proximity and low privileges, and there is no evidence of active exploitation in the wild at this time.

For European organizations using xlang-ai OpenAgents, this vulnerability poses a moderate risk. If exploited, attackers could gain unauthorized access to sensitive files or modify critical data, potentially leading to data breaches or operational disruptions. Organizations in sectors with high data sensitivity—such as finance, healthcare, and government—may face increased risks due to the potential exposure of confidential information. The lack of available patches and the vendor's decision not to plan a fix increases the risk of prolonged exposure. Additionally, the continuous delivery model without clear versioning complicates vulnerability management and incident response. The impact may be exacerbated in environments where OpenAgents is integrated with other critical systems or where file system permissions are misconfigured, allowing broader access. While no known exploits are currently active, the public disclosure increases the likelihood of future exploitation attempts, especially by attackers with network access. European organizations with adjacent network access to vulnerable instances should consider this vulnerability a significant operational risk.

Given the absence of official patches, European organizations should implement the following specific mitigations: 1) Restrict network access to the OpenAgents service to trusted hosts and networks only, using firewalls and network segmentation to limit exposure to adjacent network attackers. 2) Harden file system permissions on servers running OpenAgents to ensure that the application process has the minimum necessary privileges, preventing unauthorized file access or modification outside designated directories. 3) Implement application-layer controls such as input validation and sanitization proxies or web application firewalls (WAFs) configured to detect and block path traversal patterns targeting the create_upload_file endpoint. 4) Monitor logs and file system activity for unusual access patterns or unauthorized file changes that may indicate exploitation attempts. 5) Consider deploying runtime application self-protection (RASP) tools to detect and block exploitation attempts in real-time. 6) Evaluate the feasibility of replacing or isolating the vulnerable OpenAgents component until a secure version or patch is available. 7) Engage with the vendor or community to track any future updates or unofficial patches. These measures go beyond generic advice by focusing on network-level restrictions, file system hardening, and proactive detection tailored to the specific vulnerability vector.
