CVE-2024-34706

@valtimo/components exposes access token to form.io

Attack requirements

The following conditions have to be met in order to perform this attack:

• An attacker needs to have access to the network traffic on the api.form.io domain.
• The content of the x-jwt-token header is logged or otherwise available to the attacker.
• An attacker needs to have network access to the Valtimo API.
• An attacker needs to act within the time-to-live of the access token. The default TTL in Keycloak is 5 minutes.

When opening a form in Valtimo, the access token (JWT) of the user is exposed to api.form.io via the the x-jwt-token header. An attacker can retrieve personal information from this token, or use it to execute requests to the Valtimo REST API on behalf of the logged-in user.

This issue is caused by a misconfiguration of the Form.io component.

CVE-2024-34706 has a CVSS score of 9.8 (Critical). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (10.8.4, 11.1.6, 11.2.2); upgrading removes the vulnerable code path.

1. What is CVE-2024-34706? CVE-2024-34706 is a critical-severity security vulnerability in @valtimo/components (npm), affecting versions < 10.8.4. It is fixed in 10.8.4, 11.1.6, 11.2.2.
2. How severe is CVE-2024-34706? CVE-2024-34706 has a CVSS score of 9.8 (Critical). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of @valtimo/components are affected by CVE-2024-34706? @valtimo/components (npm) versions < 10.8.4 is affected.
4. Is there a fix for CVE-2024-34706? Yes. CVE-2024-34706 is fixed in 10.8.4, 11.1.6, 11.2.2. Upgrade to this version or later.
5. Is CVE-2024-34706 exploitable, and should I be worried? Whether CVE-2024-34706 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2024-34706 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2024-34706?
   • Upgrade @valtimo/components to 10.8.4 or later
   • Upgrade @valtimo/components to 11.1.6 or later
   • Upgrade @valtimo/components to 11.2.2 or later
