CVE-2026-3051 in dinky
Summary
by MITRE • 02/24/2026
A vulnerability has been found in DataLinkDC dinky up to 1.2.5. The affected element is the function getProjectDir of the file dinky-admin/src/main/java/org/dinky/utils/GitRepository.java of the component Project Name Handler. Such manipulation of the argument projectName leads to path traversal. The attack may be performed from remote. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

The vulnerability identified in DataLinkDC dinky version 1.2.5 affects the GitRepository.java component within the dinky-admin module, specifically targeting the getProjectDir function that handles project name arguments. This path traversal vulnerability represents a critical security flaw that allows attackers to manipulate file paths through crafted input parameters, potentially enabling unauthorized access to sensitive system resources and data. The vulnerability exists within the Project Name Handler component where the projectName argument is processed without proper validation or sanitization, creating an exploitable condition that can be leveraged by remote attackers.
The technical implementation of this vulnerability stems from insufficient input validation within the getProjectDir function, which directly incorporates user-supplied projectName values into file path construction without adequate sanitization measures. This flaw falls under the Common Weakness Enumeration category CWE-23, which describes improper limitation of a pathname to a restricted directory, commonly known as path traversal or directory traversal attacks. The vulnerability's remote exploitability means that malicious actors can trigger this condition through network-based attacks without requiring local system access, making it particularly dangerous in web-facing applications. Attackers can manipulate the projectName parameter to include directory traversal sequences such as "../" or similar constructs to navigate outside the intended project directories and access arbitrary files on the system.
The operational impact of this vulnerability extends beyond simple unauthorized file access, as it could potentially enable attackers to read sensitive configuration files, access database credentials, examine source code repositories, or even execute arbitrary code if the application has sufficient privileges. The fact that the exploit has been publicly disclosed and is actively usable significantly increases the risk profile, as security researchers and malicious actors alike can leverage this weakness without requiring advanced technical skills or extensive reconnaissance. The vulnerability's disclosure without vendor response represents a critical failure in the security update process, leaving users exposed to potential exploitation without any official patch or mitigation guidance.
Organizations utilizing DataLinkDC dinky versions up to 1.2.5 should immediately implement mitigations including input validation and sanitization of all user-supplied parameters, particularly those used in file path construction. The recommended approach involves implementing strict validation of the projectName argument to prevent directory traversal sequences and ensuring that all file operations occur within designated safe directories. Additionally, the application should employ proper access controls and privilege separation to limit the damage that could occur even if exploitation succeeds. Security teams should consider implementing network-based controls such as firewall rules and web application firewalls to restrict access to potentially vulnerable endpoints while awaiting official vendor patches. The vulnerability also highlights the importance of maintaining up-to-date software components and establishing effective vulnerability disclosure and response procedures with software vendors to prevent extended periods of exposure without remediation options.
