Summary
Missing security headers in Action Pack on non-HTML responses
Permissions-Policy is Only Served on HTML Content-Type
The application configurable Permissions-Policy is only served on responses
with an HTML related Content-Type.
This has been assigned the CVE identifier CVE-2024-28103.
Versions Affected: >= 6.1.0
Not affected: < 6.1.0
Fixed Versions: 6.1.7.8, 7.0.8.4, and 7.1.3.4
Impact
Responses with a non-HTML Content-Type are not serving the configured Permissions-Policy. There are certain non-HTML Content-Types that would benefit from having the Permissions-Policy enforced.
Releases
The fixed releases are available at the normal locations.

Impact
The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths. Typical impact: varies by context: data corruption, logic bypass, or denial of service.
CVE-2024-28103 has a CVSS score of 5.4 (Medium). The vector is network-reachable, no 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 (6.1.7.8, 7.0.8.4, 7.1.3.4, 7.2.0.beta2); 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. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2024-28103? CVE-2024-28103 is a medium-severity improper input validation vulnerability in actionpack (rubygems), affecting versions >= 6.1.0, < 6.1.7.8. It is fixed in 6.1.7.8, 7.0.8.4, 7.1.3.4, 7.2.0.beta2. The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths.
- How severe is CVE-2024-28103? CVE-2024-28103 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.
- Which versions of actionpack are affected by CVE-2024-28103? actionpack (rubygems) versions >= 6.1.0, < 6.1.7.8 is affected.
- Is there a fix for CVE-2024-28103? Yes. CVE-2024-28103 is fixed in 6.1.7.8, 7.0.8.4, 7.1.3.4, 7.2.0.beta2. Upgrade to this version or later.
- Is CVE-2024-28103 exploitable, and should I be worried? Whether CVE-2024-28103 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-2024-28103 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.
