An elevation of privilege vulnerability exists when Azure DevOps Server and Team Foundation Services improperly handle 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 Azure DevOps Server and Team Foundation Services updater handles these tokens.
