CVE-2024-28056
CRITICALAWS Amplify CLI has incorrect trust policy management
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
Amazon AWS Amplify CLI before 12.10.1 incorrectly configures the role trust policy of IAM roles associated with Amplify projects. When the Authentication component is removed from an Amplify project, a Condition property is removed but "Effect":"Allow" remains present, and consequently sts:AssumeRoleWithWebIdentity would be available to threat actors with no conditions. Thus, if Amplify CLI had been used to remove the Authentication component from a project built between August 2019 and January 2024, an "assume role" may have occurred, and may have been leveraged to obtain unauthorized access to an organization's AWS resources. NOTE: the problem could only occur if an authorized AWS user removed an Authentication component. (The vulnerability did not give a threat actor the ability to remove an Authentication component.) However, in realistic situations, an authorized AWS user may have removed an Authentication component, e.g., if the objective were to stop using built-in Cognito resources, or move to a completely different identity provider.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @aws-amplify/cli. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update @aws-amplify/cli to 12.10.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-28056 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 pinpoints whether CVE-2024-28056 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2024-28056. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2024-28056 in your dependencies?
O3 detects CVE-2024-28056 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
