Apache APISIX (including this ingress controller) follows the Apache Software Foundation's vulnerability-disclosure policy. Please report security vulnerabilities to the ASF Security team at security@apache.org per https://www.apache.org/security/.
This repository inherits the Apache APISIX project threat model at:
https://github.com/apache/apisix/blob/master/docs/en/latest/security-threat-model.md
Of particular relevance to apisix-ingress-controller:
§4.8 covers a CRD-to-Admin-API fidelity invariant specific
to this controller (silent drop / injection / rename
between the apisix.apache.org CRD spec and the Admin API
target is a controller bug).
