Deploy Microsoft Developer Tools update for Visual Studio Code

Linked CVEs: 5
Confirmed exploited: 0
PoC or lab evidence: 0
Maximum CVSS: 9.6

Evidence is kept separate

Confirmed exploitation, public exploit material, EPSS probability and CVSS severity answer different questions. “No confirmation recorded” means the checked sources do not currently confirm exploitation. It is not proof that exploitation has not occurred.
