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.","cvss_v4":{"vector":"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","score":9.4},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9},"cwes":["CWE-863"],"references":["https://github.com/akuity/kargo/commit/155c6852ffbffa2902f18e6c7add91a846e8d344","https://github.com/akuity/kargo/security/advisories/GHSA-7g9x-cp9g-92mr"],"products":["akuity:kargo"],"source":"nvd","synced_at":"2026-10-19T22:24:17.937441719+00:00"},"epss":{"cve":"CVE-2026-27112","score":0.00491,"percentile":0.42221,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7g9x-cp9g-92mr","url":"https://osv.dev/vulnerability/GHSA-7g9x-cp9g-92mr","summary":"Kargo has an Authorization Bypass Vulnerability in Batch Resource Creation API Endpoints","modified":"2026-02-23T23:43:51.751260Z","packages":[{"ecosystem":"Go","name":"github.com/akuity/kargo","purl":"pkg:golang/github.com/akuity/kargo","ranges":[">=1.9.0-rc.1 <1.9.3"],"fixed":["1.9.3"]},{"ecosystem":"Go","name":"github.com/akuity/kargo","purl":"pkg:golang/github.com/akuity/kargo","ranges":[">=1.8.0-rc.1 <1.8.11"],"fixed":["1.8.11"]},{"ecosystem":"Go","name":"github.com/akuity/kargo","purl":"pkg:golang/github.com/akuity/kargo","ranges":[">=1.7.0 <1.7.8"],"fixed":["1.7.8"]}]},{"id":"GO-2026-4516","url":"https://osv.dev/vulnerability/GO-2026-4516","summary":"Kargo has an Authorization Bypass Vulnerability in Batch Resource Creation API Endpoints in github.com/akuity/kargo","modified":"2026-02-23T19:26:01.162320Z","packages":[{"ecosystem":"Go","name":"github.com/akuity/kargo","purl":"pkg:golang/github.com/akuity/kargo","ranges":[">=1.7.0 <1.7.8",">=1.8.0-rc.1 <1.8.11",">=1.9.0-rc.1 <1.9.3"],"fixed":["1.7.8","1.8.11","1.9.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
