Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.github.talelin:lin-cms-core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
The records we use list no patched version of io.github.talelin:lin-cms-core for CVE-2022-32430. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
Mitigate without a patch
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
How to detect CVE-2022-32430
A community-maintained Nuclei template exists for this CVE. You can scan for it directly:

- Lin CMS Spring Boot - Default JWT Token
- Severity
- high
- Impact
- Unauthenticated attackers can access backend administrative information and functions using a hardcoded default JWT token, potentially gaining complete control over the Lin CMS Spring Boot application including user management and content administration.
- Remediation
- Update Lin CMS Spring Boot to a version later than 0.2.1 that uses unique JWT secret keys, removes hardcoded tokens, and implements proper token rotation.
