# CVE-2024-42480: RBAC Roles for `etcd` created by Kamaji are not disjunct

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.6% , percentile 49: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 49% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes github.com/clastix/kamaji (Go) <= 1.0.0, no fixed version listed . Check your lockfile, including transitive dependencies.

## What it is

Kamaji is the Hosted Control Plane Manager for Kubernetes. In versions 1.0.0 and earlier, Kamaji uses an "open at the top" range definition in RBAC for etcd roles leading to some TCPs API servers being able to read, write, and delete the data of other control planes. This vulnerability is fixed in edge-24.8.2.

## Affected packages

- Go `github.com/clastix/kamaji` <= 1.0.0 → fixed: none listed

## Affected products (CVE record)

- clastix kamaji: <= 1.0.0

## Severity

- GitHub_M CVSS 3.1: 8.1 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N`
- GitHub CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable no , technical impact partial .
- FIRST EPSS (model of 2026-10-21): 0.62% probability of exploitation activity in the next 30 days; percentile 49.
