CVE-2025-69288 Overview
CVE-2025-69288 is a Remote Code Execution (RCE) vulnerability affecting Titra, an open source project time tracking software developed by Kromit. The vulnerability exists in versions prior to 0.99.49 and allows authenticated Admin users to execute arbitrary code on the server by manipulating the timeEntryRule database field. This field is passed directly to a NodeVM instance for execution without proper sanitization, enabling attackers with administrative privileges to achieve full server compromise.
Critical Impact
Authenticated administrators can exploit unsanitized input passed to NodeVM to execute arbitrary code on the server, potentially leading to complete system compromise, data exfiltration, and lateral movement within the network.
Affected Products

Technical Details for CVE-2025-69288
Vulnerability Analysis
This vulnerability stems from improper input validation (CWE-20) in how Titra handles the timeEntryRule configuration parameter. The application allows Admin users to modify this value in the database, which is subsequently executed within a NodeVM sandbox environment. However, due to insufficient sanitization of user-supplied input before execution, attackers can craft malicious payloads that escape the sandbox context or leverage NodeVM capabilities to execute arbitrary system commands.
The attack requires authenticated access with Admin-level privileges, but once exploited, provides the attacker with code execution capabilities on the underlying server. This can lead to complete system compromise, including access to sensitive time tracking data, user credentials, and the ability to pivot to other systems in the network infrastructure.
Root Cause
The root cause of this vulnerability is the lack of input sanitization on the timeEntryRule parameter before it is passed to the NodeVM execution engine. The application trusts that Admin users will only input legitimate business logic rules, but fails to validate or sanitize the content to prevent code injection attacks. This violates the principle of defense-in-depth, where even privileged user input should be validated before execution in any code evaluation context.
Attack Vector
The attack is network-based and requires an authenticated session with administrative privileges. An attacker who has compromised Admin credentials (through phishing, credential stuffing, or other means) or a malicious insider with Admin access can:
- Authenticate to the Titra application with Admin credentials
- Navigate to the configuration area where timeEntryRule can be modified
- Inject malicious JavaScript/Node.js code into the timeEntryRule field
- Trigger the execution of the rule, causing the malicious payload to execute on the server
The vulnerability allows for Remote Code Execution due to the direct passage of unsanitized user input to the NodeVM execution context. Attack complexity is low once Admin access is obtained, and the scope is changed, meaning successful exploitation can affect resources beyond the vulnerable component.
Detection Methods for CVE-2025-69288
Indicators of Compromise
- Unexpected modifications to the timeEntryRule field in the Titra database
- Unusual process spawning from the Titra Node.js application process
- Network connections from the Titra server to unexpected external hosts
- Log entries showing Admin users modifying time entry rules with suspicious content containing system commands or encoded payloads
Detection Strategies
- Monitor database audit logs for changes to the timeEntryRule configuration field
- Implement application-level logging to capture all modifications to critical configuration parameters
- Deploy endpoint detection and response (EDR) solutions to detect anomalous child process creation from Node.js applications
- Use network monitoring to identify unusual outbound connections from application servers
Monitoring Recommendations
- Enable verbose logging in Titra to capture all administrative actions
- Configure SIEM alerts for any modifications to critical configuration tables
- Monitor for signs of NodeVM sandbox escape attempts in application logs
- Implement file integrity monitoring on the Titra application directory to detect unauthorized modifications
How to Mitigate CVE-2025-69288
Immediate Actions Required
- Upgrade Titra to version 0.99.49 or later immediately
- Review database logs for any suspicious modifications to timeEntryRule fields
- Audit Admin user accounts and revoke access for any potentially compromised or unnecessary accounts
- Implement network segmentation to limit the blast radius of potential exploitation
Patch Information
Kromit has released version 0.99.49 which addresses this vulnerability. The fix can be obtained from the GitHub Release v0.99.49. Additional details about the security fix are available in the GitHub Commit Update and the GitHub Security Advisory GHSA-pqgx-6wg3-gmvr.
Workarounds
- Restrict Admin access to only essential personnel until the patch can be applied
- Implement additional access controls or network restrictions limiting who can access the Admin interface
- Consider temporarily disabling the timeEntryRule functionality if business operations permit
- Deploy Web Application Firewall (WAF) rules to monitor and block suspicious payloads targeting configuration endpoints
# Upgrade Titra to patched version
cd /path/to/titra
git fetch --tags
git checkout 0.99.49
