CVE-2026-55449 in CloudBeaver
Summary
by MITRE • 11/06/2026
CloudBeaver is a cloud database manager. Prior to 26.1.2, its resource-management project resolution accepts project identifiers without validating that they are safe path components. An authenticated user with resource-management privileges can supply a crafted project identifier that causes path resolution to escape the shared-projects directory and enumerate directory names elsewhere on the server. This can disclose filesystem layout information. Arbitrary file reads, writes, and deletion are not confirmed. The issue is fixed in 26.1.2 by validating project names before resolving the shared-project path.

CloudBeaver serves as a cloud-based database management tool that facilitates interaction with various data sources through a web interface. A significant security vulnerability was identified within its resource-management module, specifically concerning how it handles project identifiers during directory resolution operations. This flaw exists in versions prior to 26.1.2 and stems from an insufficient validation mechanism for user-supplied input. The core technical issue lies in the application's failure to sanitize or validate project names before using them as components in file system path construction. When a user provides a crafted identifier containing directory traversal sequences, such as dot-dot-slash patterns, the underlying logic processes these characters without adequate restriction, allowing the resulting path to escape the intended shared-projects directory boundary.
The operational impact of this vulnerability is primarily centered on information disclosure and potential reconnaissance activities against the host server's file system structure. An authenticated user who possesses resource-management privileges can exploit this flaw by submitting maliciously crafted project identifiers in their API requests or interface interactions. By doing so, they can manipulate the path resolution logic to access directories outside the sandboxed environment intended for shared projects. This capability enables the attacker to enumerate directory names and infer aspects of the server's filesystem layout. While the vendor has noted that arbitrary file reads, writes, or deletions have not been confirmed as directly achievable through this specific vector, the ability to map out the underlying operating system structure provides valuable intelligence for further exploitation attempts. Such exposure can aid attackers in identifying sensitive configuration files, application binaries, or other critical assets located on the server.
From a classification perspective, this vulnerability aligns with CWE-22: Improper Limitation of a Pathname to a Restricted Directory, commonly known as path traversal. The attack vector leverages the lack of input validation to bypass access controls that are supposed to restrict file system operations to specific directories. In terms of offensive security frameworks, this behavior corresponds to ATT&CK technique T1083: File and Directory Discovery, where adversaries explore the local file system to gather information necessary for subsequent stages of an intrusion campaign. The vulnerability highlights a critical gap in input validation practices within web applications that handle user-defined paths or identifiers, emphasizing the necessity of strict allow-listing rather than relying on blacklist-based filtering which can be easily bypassed using encoding variations or traversal sequences.
To mitigate this risk, organizations running CloudBeaver must upgrade to version 26.1.2 or later immediately. The fix implemented in this release introduces robust validation logic that checks project names for safe path components before they are used in directory resolution operations. This ensures that any attempt to inject traversal characters is rejected at the application layer, preventing the escape from the designated shared-projects directory. In addition to upgrading, administrators should enforce strict access controls on resource-management privileges, ensuring that only trusted users have the ability to create or manage projects. Implementing web application firewalls with rules specifically designed to detect and block path traversal patterns can also provide an additional layer of defense during the transition period. Regular security audits and code reviews focusing on file system interactions are recommended to prevent similar vulnerabilities in future development cycles, ensuring that all user inputs interacting with server resources undergo rigorous sanitization and validation processes consistent with industry best practices for secure coding.
