An elevation of privilege vulnerability exists when Visual Studio improperly handles pipeline job tokens. An attacker who successfully exploited this vulnerability could extend their access to a project. To exploit this vulnerability, an attacker would first have to have access to the project and swap the short-term token for a long-term one. The update addresses the vulnerability by correcting how the Visual Studio updater handles these tokens.
The authentication scheme or implementation uses key data elements that are assumed to be immutable, but can be controlled or modified by the attacker.
