MEDIUM

go_cors < 1.3.0 - Origin Validation Error via Wildcard CORS Policy

Title source: llm
STIX 2.1

Description

The Olivier Poitrey Go CORS handler through 1.3.0 actively converts a wildcard CORS policy into reflecting an arbitrary Origin header value, which is incompatible with the CORS security design, and could lead to CORS misconfiguration security problems.
