Grafana’s SCIM Security Flaw: A 10 Out of 10 on the “Oops” Scale!
Grafana has patched a severe security flaw in its SCIM component, which could let attackers impersonate users or escalate privileges. A CVSS score of 10.0 means this is as serious as realizing you’ve been using decaf coffee for months. Users should update immediately to avoid any unwanted surprises.
Hot Take:
Grafana just went full throttle on the ‘Oops, Whoops’ express with a vulnerability so severe it could make a hacker’s day faster than you can say ‘cross-domain identity management’. If you thought your identity was safe, think again – or at least until you’ve updated your software.
Key Points:
- Grafana’s SCIM flaw has a perfect CVSS score of 10.0 – that’s a security nightmare in tech speak.
- Impacts Grafana Enterprise versions 12.0.0 to 12.2.1 with SCIM provisioning enabled.
- Allows user impersonation and privilege escalation through numeric externalId trickery.
- Patched in versions 12.0.6+security-01, 12.1.3+security-01, 12.2.1+security-01, and the freshly baked 12.3.0.
- Discovered on November 4, 2025, during an internal audit. Better late than never?
