Summary

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.

Exploit prediction (EPSS)

0.72% probability of exploitation in the next 30 days, higher than 54% of all scored CVEs.
