What is CVE-2014-7922?
CVE-2014-7922 is a medium-severity authentication bypass vulnerability in n/a, published on 23 Feb 2015. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
The GoogleAuthUtil.getToken method in the Google Play services SDK before 2015 sets parameters in OAuth token requests upon finding a corresponding _opt_ parameter in the Bundle extras argument, which allows attackers to bypass an intended consent dialog and retrieve tokens for arbitrary OAuth scopes including the SID and LSID scopes, and consequently obtain access to a Google account, via a crafted application, as demonstrated by setting the has_permission=1 parameter value upon finding _opt_has_permission in that argument.
