CVE-2026-1022 is a vulnerability classified under CWE-23 (Relative Path Traversal) affecting the Gotac Statistics Database System. This vulnerability allows an unauthenticated remote attacker to exploit improper input validation in file path handling, enabling arbitrary file read operations on the server hosting the database system. Specifically, the attacker can craft requests that include relative path sequences (e.g., '../') to traverse directories and access sensitive files outside the intended directory scope. The vulnerability does not require any authentication or user interaction, making it highly accessible for exploitation. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and high impact on confidentiality (VC:H) with no impact on integrity or availability. The flaw could lead to exposure of critical system files, configuration files, or sensitive data stored on the server, which could be leveraged for further attacks such as privilege escalation or lateral movement. Although no public exploits have been reported yet, the vulnerability's characteristics suggest it could be weaponized quickly. The affected product version is indicated as '0', which may imply an initial or early release version, suggesting that newer versions might not be affected or that the vendor has yet to release a patch. The vulnerability was published on January 16, 2026, and assigned by TW-CERT. No patches or mitigations have been officially released at the time of this report.

For European organizations, the impact of CVE-2026-1022 can be significant, especially for those relying on the Gotac Statistics Database System for handling sensitive or critical data. The arbitrary file read capability can lead to exposure of confidential information such as internal configuration files, credentials, or personally identifiable information (PII), violating data protection regulations like GDPR. This exposure can damage organizational reputation, lead to regulatory fines, and facilitate further attacks such as privilege escalation or network infiltration. Critical infrastructure sectors, including finance, healthcare, and government agencies, which often use statistical databases for decision-making and reporting, are particularly vulnerable. The lack of authentication requirement increases the risk of widespread exploitation, potentially allowing attackers to target multiple organizations remotely. Additionally, the vulnerability could be exploited as a foothold for advanced persistent threats (APTs) aiming to conduct espionage or sabotage. The overall availability of the system is not directly impacted, but confidentiality breaches alone pose severe risks to European entities.

Given the absence of an official patch, European organizations should implement immediate compensating controls to mitigate CVE-2026-1022. First, deploy strict input validation and sanitization mechanisms on all user-supplied file path inputs to prevent directory traversal sequences. If source code access is available, modify the application logic to canonicalize and validate file paths against an allowlist of permissible directories. Second, implement Web Application Firewalls (WAFs) with rules specifically designed to detect and block path traversal patterns such as '../' sequences in HTTP requests. Third, restrict file system permissions of the database system process to the minimum necessary, ensuring it cannot access sensitive files outside its designated directories. Fourth, segment the network to isolate the database system from public-facing networks, limiting exposure to unauthenticated attackers. Fifth, monitor logs and network traffic for unusual file access attempts or suspicious activity indicative of exploitation attempts. Finally, maintain close communication with Gotac for timely patch releases and apply updates promptly once available.
