# CVE-2025-47284: Gardener allows metadata injection for a project secret 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 0.5% , percentile 40: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 40% of all scored CVEs (low). 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 the gardenlet component of Gardener prior to versions 1.116.4, 1.117.5, 1.118.2, and 1.119.0. It 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 where gardener/gardener-extension-provider-gcp is in use. Versions 1.116.4, 1.117.5, 1.118.2, and 1.119.0 fix the issue.

- 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): 0.47% probability of exploitation activity in the next 30 days; percentile 40.
