## Detection & mitigation playbook

Open-source dependency

1.  ### Detect
    
    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/casdoor/casdoor, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
    
2.  ### Remediation status
    
    The records we use list no patched version of github.com/casdoor/casdoor for CVE-2026-5468. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
    
3.  ### Mitigate without a patch
    
    Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
