Summary
Workarounds
Limiting access to /validate/check to client applications (i.e. Shibboleth/FreeRADIUS) using an authorization policy with api_key_required or using e.g. the reverse proxy.
Impact
If the resolver parameter is passed, but the user does not exist, all failcounters of tokens in that resolver will be increased.
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.
GHSA-74R7-3MJM-JC5V has a CVSS score of 6.5 (Medium). 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 (2.9.1); 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.
Remediation advice
This, along with other issues, was fixed in eduMFA v2.9.1.
Frequently Asked Questions
- What is GHSA-74R7-3MJM-JC5V? GHSA-74R7-3MJM-JC5V is a medium-severity improper input validation vulnerability in edumfa (pip), affecting versions < 2.9.1. It is fixed in 2.9.1. The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths.
- How severe is GHSA-74R7-3MJM-JC5V? GHSA-74R7-3MJM-JC5V has a CVSS score of 6.5 (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 edumfa are affected by GHSA-74R7-3MJM-JC5V? edumfa (pip) versions < 2.9.1 is affected.
- Is there a fix for GHSA-74R7-3MJM-JC5V? Yes. GHSA-74R7-3MJM-JC5V is fixed in 2.9.1. Upgrade to this version or later.
- Is GHSA-74R7-3MJM-JC5V exploitable, and should I be worried? Whether GHSA-74R7-3MJM-JC5V 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 GHSA-74R7-3MJM-JC5V 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.
