Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-27112 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/akuity/kargo (Go): affected from 1.7.0; fixed in 1.7.8, 1.8.11, 1.9.3\n- github.com/akuity/kargo (Go): affected from 1.7.0; fixed in 1.7.8\n- github.com/akuity/kargo (Go): affected from 1.7.0; fixed in 1.7.8\n- github.com/akuity/kargo (Go): affected from 1.8.0-rc.1; fixed in 1.8.11\n- github.com/akuity/kargo (Go): affected from 1.8.0-rc.1; fixed in 1.8.11\n- github.com/akuity/kargo (Go): affected from 1.9.0-rc.1; fixed in 1.9.3\n- github.com/akuity/kargo (Go): affected from 1.9.0-rc.1; fixed in 1.9.3\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-27112/ (Markdown: https://insights.sbomify.com/CVE-2026-27112/index.md)","id":"CVE-2026-27112","markdown":"https://insights.sbomify.com/CVE-2026-27112/index.md","name":"CVE-2026-27112","record":{"aliases":["GHSA-7g9x-cp9g-92mr","GO-2026-4516"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Kargo artifact promotion","requires_auth":"low_privilege","summary":"Attackers can bypass authorization in Kargo's batch API to inject resources, escalate privileges, and achieve remote code execution or secret exfiltration.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"kargo","vendor":"akuity"}],"cvss":{"score":9.4,"severity":"critical","source":"cna","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","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"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.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Kargo has an Authorization Bypass Vulnerability in Batch Resource Creation API Endpoints","id":"CVE-2026-27112","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":7,"n_references":2,"next":{"headline":"Liquid Prompt arbitrary command injection via crafted Git branch names in gitstatusd backend","id":"CVE-2026-27113"},"packages":[{"ecosystem":"Go","fixed":["1.7.8","1.8.11","1.9.3"],"introduced":["1.7.0","1.8.0-rc.1","1.9.0-rc.1"],"last_affected":[],"package":"github.com/akuity/kargo","purl":"pkg:golang/github.com/akuity/kargo","source":"GO-2026-4516"},{"ecosystem":"Go","fixed":["1.7.8"],"introduced":["1.7.0"],"last_affected":[],"package":"github.com/akuity/kargo","purl":null,"source":"GHSA-7g9x-cp9g-92mr"},{"ecosystem":"Go","fixed":["1.7.8"],"introduced":["1.7.0"],"last_affected":[],"package":"github.com/akuity/kargo","purl":"pkg:golang/github.com/akuity/kargo","source":"GHSA-7g9x-cp9g-92mr"},{"ecosystem":"Go","fixed":["1.8.11"],"introduced":["1.8.0-rc.1"],"last_affected":[],"package":"github.com/akuity/kargo","purl":null,"source":"GHSA-7g9x-cp9g-92mr"},{"ecosystem":"Go","fixed":["1.8.11"],"introduced":["1.8.0-rc.1"],"last_affected":[],"package":"github.com/akuity/kargo","purl":"pkg:golang/github.com/akuity/kargo","source":"GHSA-7g9x-cp9g-92mr"},{"ecosystem":"Go","fixed":["1.9.3"],"introduced":["1.9.0-rc.1"],"last_affected":[],"package":"github.com/akuity/kargo","purl":null,"source":"GHSA-7g9x-cp9g-92mr"},{"ecosystem":"Go","fixed":["1.9.3"],"introduced":["1.9.0-rc.1"],"last_affected":[],"package":"github.com/akuity/kargo","purl":"pkg:golang/github.com/akuity/kargo","source":"GHSA-7g9x-cp9g-92mr"}],"prev":{"headline":"Kargo has Missing Authorization Vulnerabilities in Approval \u0026 Promotion REST API Endpoints","id":"CVE-2026-27111"},"products":["kargo"],"published":"2026-02-20","related":[{"cvss_score":6.9,"headline":"Kargo's `GetConfig()` and `RefreshResource()` API endpoints allow unauthenticated access","id":"CVE-2026-24748","kev_date_added":null,"published":"2026-01-27"},{"cvss_score":5.3,"headline":"Kargo has Missing Authorization Vulnerabilities in Approval \u0026 Promotion REST API Endpoints","id":"CVE-2026-27111","kev_date_added":null,"published":"2026-02-20"},{"cvss_score":5.1,"headline":"Kargo: SSRF in Promotion http/http-download Steps Enables Internal Network Access and Data Exfiltration","id":"CVE-2026-32828","kev_date_added":null,"published":"2026-03-20"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-02-24","vendors":["akuity"]},"summary":"Attackers can bypass authorization in Kargo's batch API to inject resources, escalate privileges, and achieve remote code execution or secret exfiltration.","url":"https://insights.sbomify.com/CVE-2026-27112/"}
