Description
This PR proposes to revert the change made in #295 to address CVE-2024-5798.
We add a new test
TestLoginBoundAudiences
to test the behavior expectations.Background
#295 fixed a bug where the login JWT's
aud
claim is ignored if it is a single string. The net effect is that the role'sbound_audiences
parameter must match at least one of the JWT'saud
claims if the token has anaud
claim.Since the behavior change is a breaking change, we are reverting the change in the Vault versions after 1.15.10 and 1.16.4. However, the behavior change will go into effect in Vault 1.17 and later.
