What exactly is the difference between following two headers: Authorization : Bearer cn389ncoiwuencr vs Authorization : cn389ncoiwuencr All the sources which I have gone through, sets...
Note that the JWT bearer token doesn't contain the client credentials and may have to be combined with client authentication. For example, in the Microsoft On-Behalf-Of flow, the authorization server expects both a JWT bearer token as part of the grant and client credentials for authentication (either a shared secret or another JWT bearer token).
Who gets a bearer token, will have all the privileges of the actual owner of the token. Is there any tokening mechanism which is not suffering from this issue?
Would this approach actually work to prevent CSRF attacks? Yes. An attacker can't make a browser send a request that includes the authorization header with the correct bearer token. This is for two reasons: The attacker can't set the authorization header. The attacker doesn't know the correct value of the token, so they wouldn't know what to set it to. However, this might be sensitive to ...

As such, any site that uses bearer tokens as its only form of session authentication is automatically secure against CSRF and CORS misconfiguration, as the attacker will never know the value to send in the Authorization header (or, if the attacker does know, then they can just send the request ...
Bearer tokens, or other HTTP header based tokens that need to be added manually, would prevent you from CSRF. Of course, but sort of off-topic, if you have a XSS vulnerability, an attacker could still access these tokens, but then it doesn't become a CSRF bug.
