Summary

Summary An authorization bypass vulnerability exists in the Mautic 7 API v2 endpoints (utilizing API Platform). Under certain conditions, roles configured with owner-scope restrictions (such as viewown or editown) are not properly enforced. This allows low-privilege authenticated API users to bypass ownership-logic controls and access or modify resources belonging to other users. Impact Authenticated API users with limited roles can read or modify restricted resources, including reports, contacts, and companies, that they do not own and should not have access to. This bypasses structural tenant and privilege boundaries on the platform. Patched Versions This security issue has been addressed in the following release: 7.1.2 Note: Mautic 6.x, 5.x, and 4.x branches are not affected by this vulnerability. For general security support regarding legacy Mautic 4 releases, please refer to the ELTS page.* Workarounds There are no official workarounds. To mitigate this issue without upgrading, temporarily revoke API credentials or narrow access permissions for any users whose roles rely on owner-scope permission containment.

Impact

What is incorrect authorization?

The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions. Typical impact: unauthorized data access or execution of privileged operations.

Severity and exposure

CVE-2026-9808 has a CVSS score of 7.1 (High). The vector is network-reachable, low 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 (7.1.2). Upgrading removes the vulnerable code path.

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

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 instead of chasing every advisory.

Kodem's runtime-powered SCA identifies whether CVE-2026-9808 is reachable in your applications. Explore open-source security for your team.

Frequently asked questions about CVE-2026-9808

What is CVE-2026-9808?

CVE-2026-9808 is a high-severity incorrect authorization vulnerability in mautic/core (composer), affecting versions >= 7.0.0, < 7.1.2. It is fixed in 7.1.2. The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions.

How severe is CVE-2026-9808?

CVE-2026-9808 has a CVSS score of 7.1 (High). 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.

Which versions of mautic/core are affected by CVE-2026-9808?

mautic/core (composer) versions >= 7.0.0, < 7.1.2 is affected.

Is there a fix for CVE-2026-9808?

Yes. CVE-2026-9808 is fixed in 7.1.2. Upgrade to this version or later.

Is CVE-2026-9808 exploitable, and should I be worried?

Whether CVE-2026-9808 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.

What actually determines whether CVE-2026-9808 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.

How do I fix CVE-2026-9808?

Upgrade mautic/core to 7.1.2 or later.
