How to Validate a Vulnerability Fix When Several Versions Run at Once

11/11/2026

A rolling deployment may leave old vulnerable instances serving some requests after the main service reports an update.

Checks to make

Confirm the in-scope instance pool, inspect version metadata and deployment status, and validate each relevant route using safe authorized methods. Record residual old versions and do not close the finding until rollout and evidence align.
