# CVE-2026-27112: Kargo has an Authorization Bypass Vulnerability in Batch Resource Creation API Endpoints

**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 0.9% , percentile 59: FIRST’s model estimates a 0.9% chance of exploitation activity in the next 30 days, higher than 59% 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/akuity/kargo (Go) >= 1.9.0-rc.1, < 1.9.3, fixed in 1.9.3 ; github.com/akuity/kargo (Go) >= 1.8.0-rc.1, < 1.8.11, fixed in 1.8.11 ; github.com/akuity/kargo (Go) >= 1.7.0, < 1.7.8, fixed in 1.7.8 . Check your lockfile, including transitive dependencies.

## What it is

Kargo manages and automates the promotion of software artifacts. From 1.7.0 to before v1.7.8, v1.8.11, and v1.9.3, the batch resource creation endpoints of both Kargo's legacy gRPC API and newer REST API accept multi-document YAML payloads. Specially crafted payloads can manifest a bug present in the logic of both endpoints to inject arbitrary resources (of specific types only) into the underlying namespace of an existing Project using the API server's own permissions when that behavior was not intended. Critically, an attacker may exploit this as a vector for elevating their own permissions, which can then be leveraged to achieve remote code execution or secret exfiltration. Exfiltrated artifact repository credentials can be leveraged, in turn, to execute further attacks. In some configurations of the Kargo control plane's underlying Kubernetes cluster, elevated permissions may additionally be leveraged to achieve remote code execution or secret exfiltration using kubectl. This can reduce the complexity of the attack, however, worst case scenarios remain entirely achievable even without this. This vulnerability is fixed in v1.7.8, v1.8.11, and v1.9.3.

## Affected packages

- Go `github.com/akuity/kargo` >= 1.9.0-rc.1, < 1.9.3 → fixed: 1.9.3
- Go `github.com/akuity/kargo` >= 1.8.0-rc.1, < 1.8.11 → fixed: 1.8.11
- Go `github.com/akuity/kargo` >= 1.7.0, < 1.7.8 → fixed: 1.7.8

## Affected products (CVE record)

- akuity kargo: >= 1.9.0-rc.1, < 1.9.3, >= 1.8.0-rc.1, < 1.8.11, >= 1.7.0, < 1.7.8

## Severity

- GitHub_M CVSS 4.0: 9.4 `CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H`
- GitHub CVSS 4.0: 9.4 `CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.88% probability of exploitation activity in the next 30 days; percentile 59.
