CVE-2024-12393

Drupal uses JavaScript to render status messages in some cases and configurations. In certain situations, the status messages are not adequately sanitized. This issue affects Drupal Core: from 8.8.0 before 10.2.11, from 10.3.0 before 10.3.9, from 11.0.0 before 11.0.8.

Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.

CVE-2024-12393 has a CVSS score of 5.4 (Medium). The vector is network-reachable, low privileges required, and user interaction required. 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 (10.2.11, 10.3.9, 11.0.8); upgrading removes the vulnerable code path.

It is fixed in 10.2.11, 10.3.9, 11.0.8. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
2. How severe is CVE-2024-12393? CVE-2024-12393 has a CVSS score of 5.4 (Medium). 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 packages are affected by CVE-2024-12393?
   • drupal/core (composer) (versions >= 8.8.0, < 10.2.11)
   • drupal/core-recommended (composer) (versions >= 8.8.0, < 10.2.11)
   • drupal/drupal (composer) (versions >= 8.8.0, < 10.2.11)
4. Is there a fix for CVE-2024-12393? Yes. CVE-2024-12393 is fixed in 10.2.11, 10.3.9, 11.0.8. Upgrade to this version or later.
5. Is CVE-2024-12393 exploitable, and should I be worried? Whether CVE-2024-12393 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-2024-12393 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.
