The package github.com/tyktechnologies/tyk-identity-broker before 1.1.1 are vulnerable to Authentication Bypass via the Go XML parser which can cause SAML authentication bypass. This is because the XML parser doesn’t guarantee integrity in the XML round-trip (encoding/decoding XML data).
Weakness
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
