Credits
We would like to thank Oleg Andreyev, Antoine MAKDESSI for reporting the issue and Christian Flothmann for providing the fix.
Impact
The application does not adequately verify the identity of a user, device, or process before granting access. Typical impact: unauthorized access to functions or data reserved for authenticated parties.
CVE-2024-50341 has a CVSS score of 3.1 (Low). 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 (6.4.10, 7.0.10, 7.1.3); 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-2024-50341? CVE-2024-50341 is a low-severity improper authentication vulnerability in symfony/security-bundle (composer), affecting versions >= 6.2.0, < 6.4.10. It is fixed in 6.4.10, 7.0.10, 7.1.3. The application does not adequately verify the identity of a user, device, or process before granting access.
- How severe is CVE-2024-50341? CVE-2024-50341 has a CVSS score of 3.1 (Low). 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 packages are affected by CVE-2024-50341?
symfony/security-bundle(composer) (versions >= 6.2.0, < 6.4.10)symfony/symfony(composer) (versions >= 6.2.0, < 6.4.10)
- Is there a fix for CVE-2024-50341? Yes. CVE-2024-50341 is fixed in 6.4.10, 7.0.10, 7.1.3. Upgrade to this version or later.
- Is CVE-2024-50341 exploitable, and should I be worried? Whether CVE-2024-50341 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-2024-50341 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.
