Blind SQL injection in api_version parameter in Tyk Gateway version 5.0.3 allows attacker to access and dump the database via a crafted SQL query.

Blind SQL injection in api_id parameter in Tyk Gateway version 5.0.3 allows attacker to access and dump the database via a crafted SQL query.

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).

All versions of package github.com/tyktechnologies/tyk/gateway are vulnerable to Directory Traversal via the handleAddOrUpdateApi function. This function is able to delete arbitrary JSON files on the disk where Tyk is running via the management API. The APIID is provided by the user and this value is then used to create a file on disk. If there is a file found with the same name then it will be deleted and then re-created with the contents of the API creation request.
