# CVE-2025-47283: Gardener allows bypassing project secret validation which can lead to privilege escalation

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.7% , percentile 52: FIRST’s model estimates a 0.7% chance of exploitation activity in the next 30 days, higher than 52% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes github.com/gardener/gardener (Go) < 1.116.4, fixed in 1.116.4 ; github.com/gardener/gardener (Go) >= 1.117.0, < 1.117.5, fixed in 1.117.5 ; github.com/gardener/gardener (Go) >= 1.118.0, < 1.118.2, fixed in 1.118.2 . Check your lockfile, including transitive dependencies.

## What it is

Gardener implements the automated management and operation of Kubernetes clusters as a service. A security vulnerability was discovered in Gardener prior to versions 1.116.4, 1.117.5, 1.118.2, and 1.119.0 that could allow a user with administrative privileges for a Gardener project to obtain control over the seed cluster(s) where their shoot clusters are managed. This CVE affects all Gardener installations no matter of the public cloud provider(s) used for the seed clusters/shoot clusters. gardener/gardener (gardenlet) is the affected component. Versions 1.116.4, 1.117.5, 1.118.2, and 1.119.0 fix the issue.

## Affected packages

- Go `github.com/gardener/gardener` < 1.116.4 → fixed: 1.116.4
- Go `github.com/gardener/gardener` >= 1.117.0, < 1.117.5 → fixed: 1.117.5
- Go `github.com/gardener/gardener` >= 1.118.0, < 1.118.2 → fixed: 1.118.2

## Affected products (CVE record)

- gardener gardener: < 1.116.4, >= 1.117.0, < 1.117.5, >= 1.118.0, < 1.118.2

## Severity

- GitHub_M CVSS 3.0: 9.9 `CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.9 `CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.68% probability of exploitation activity in the next 30 days; percentile 52.
