Comment Seems defensible. (Score 3, Interesting) 11
From their bounty program page at https://bughunters.google.com/... :
"Insecure customer configurations (such as unconditionally injecting shared secrets or misconfiguring security-related settings) rather than a product vulnerability.}
If their published standards indicate that giving the connector that level of admin permissions is excessive, and the access needed to exploit this is as clearly a set of poor security management as the last paragraph of the summary implies, then, "Yes, it should be corrected, and no, it's not bounty worthy" seems a reasonable stance to take. It sits right in the zone of that definition.
You could have the argument, but it's not clear to me that Google has it wrong.
