Microsoft FAQ (4)

According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability?

Any authenticated attacker could trigger this vulnerability. It does not require admin or other elevated privileges.

According to the CVSS metric, successful exploitation of this vulnerability could lead to no loss of availability (A:N)? What does that mean for this vulnerability?

An attacker cannot impact the availability of the service.

According to the CVSS metric, successful exploitation of this vulnerability could lead to total loss of confidentiality (C:H)? What does that mean for this vulnerability?

An attacker who successfully exploited the vulnerability could access data that is available for the current user. Depending on the user's authorization the attacker could collect detailed data about ADO elements such as org/proj configuration, users, groups, teams, projects, pipelines, board, or wiki. An attacker could also craft page elements to collect user secrets.

According to the CVSS metric, successful exploitation of this vulnerability could lead to some loss of integrity (I:L)? What does that mean for this vulnerability?

An attacker is able to manipulate DOM model of website adding/removing elements, with crafted script is able to do actions on ADO in current user context without user consent or awareness.
