CVE-2025-69288 is a critical vulnerability identified in the open-source time tracking software Titra, maintained by kromitgmbh. The vulnerability is due to improper input validation (CWE-20) in versions prior to 0.99.49. Specifically, any authenticated user with admin privileges can modify the timeEntryRule value stored in the database. This value is subsequently passed to a NodeVM instance for execution as code. Because the input is not sanitized or validated properly before execution, an attacker can inject malicious code, leading to remote code execution (RCE). The vulnerability allows an attacker to execute arbitrary commands on the server hosting Titra, potentially compromising the entire system. The CVSS v3.1 score is 9.1 (critical), reflecting the network attack vector, low attack complexity, required high privileges (admin), no user interaction, and a scope change that affects confidentiality, integrity, and availability. The vulnerability was publicly disclosed on December 31, 2025, and fixed in version 0.99.49 of Titra. No public exploits are known at this time, but the nature of the flaw makes it a high-risk issue for any organization using vulnerable versions. The flaw is particularly dangerous because it leverages the NodeVM environment, which executes JavaScript code, allowing attackers to run arbitrary scripts with the privileges of the Titra application process.

For European organizations, exploitation of CVE-2025-69288 could lead to full system compromise of servers running vulnerable versions of Titra. Attackers with admin credentials could execute arbitrary code, potentially leading to data theft, manipulation of time tracking records, disruption of business operations, and lateral movement within internal networks. This could affect confidentiality by exposing sensitive employee or project data, integrity by altering time tracking information, and availability by causing service outages or deploying ransomware. Organizations in sectors heavily reliant on accurate time tracking, such as consulting, IT services, and project management, may face operational and financial impacts. Additionally, compromised systems could be used as pivot points for further attacks against European infrastructure. The vulnerability’s requirement for admin authentication limits exposure to insider threats or attackers who have already breached perimeter defenses, but the critical severity demands urgent remediation to prevent exploitation.

European organizations using Titra should immediately upgrade to version 0.99.49 or later, where the vulnerability is patched. Until upgrading, restrict admin access to trusted personnel only and monitor admin activities closely for suspicious modifications to timeEntryRule or other database entries. Implement network segmentation to isolate Titra servers and limit exposure to internal threats. Employ application-layer firewalls or runtime application self-protection (RASP) tools that can detect and block anomalous code execution attempts within NodeVM environments. Conduct regular audits of user privileges to ensure that only necessary users have admin rights. Additionally, enable comprehensive logging and alerting on changes to critical configuration parameters. If upgrading is delayed, consider temporarily disabling or restricting features that allow modification of timeEntryRule. Finally, integrate this vulnerability into incident response plans to ensure rapid containment if exploitation is detected.
