Comment 9 Rich Main 2019-11-15 17:14:29 UTC

It appears that the fix was pushed to Keycloak 7.0.1 (see https://github.com/keycloak/keycloak/commit/0b73685ccf3181115ae3936a578708630215ac23), but this bug states that the fix version is keycloak 8.0.0. Could you clarify why there is a discrepancy or perhaps update the fix version here?

If the fix version is really 7.0.1, I would like to get the NVD data updated to reflect that so our security scanning tools don't report a false positive. But, they are keying off of the fix version in this bug. So, I'm hoping to get things cleaned up here and then unwind...

Thanks!
