Description
Summary
BlastRADIUS (see blastradius.fail for details) also affects eduMFA prior version 2.2.0, because the Message-Authenticator attributes were not checked.
Details
Website with the vulnerability information blastradius.fail The original vulnerability has been assigned CVE-2024-3596 Case in vince: https://kb.cert.org/vuls/id/456537
PoC
There is no known proof-of-concept except for the attack shown in the paper from the researchers
Impact
An attacker can trigger an authentication flow with a RADIUS-backed token, intercept the RADIUS packet sent by eduMFA and modify the RADIUS server's answer, which would lead eduMFA to believe that the token is valid, even though the RADIUS servers answer was a reject.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for edumfa, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update edumfa to 2.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vhmj-5q9r-mm9g is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-vhmj-5q9r-mm9g can be triaged on real exposure rather than presence alone.
Tailored to GHSA-vhmj-5q9r-mm9g. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-vhmj-5q9r-mm9g in your dependencies?
O3 Security finds GHSA-vhmj-5q9r-mm9g across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
