-The vulnerability documentation explicitly references the Oauth2KeysGetHandler class and its failure to verify certificates when obtaining public keys. The linked GitHub issue #369 and security advisory both identify this handler as the source of improper certificate validation (CWE-295) and signature verification (CWE-347). The handleRequest() method is the entry point for key retrieval operations, making it the logical location for the missing validation checks.
