Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-19274 in the wild and no public exploit code.\n\nAffected product: IBM Observability with Instana (Agent). No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-19274/ (Markdown: https://insights.sbomify.com/CVE-2026-19274/index.md)","id":"CVE-2026-19274","markdown":"https://insights.sbomify.com/CVE-2026-19274/index.md","name":"CVE-2026-19274","record":{"aliases":["GHSA-v7m7-pq26-54fp"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Instana Agent","requires_auth":"low_privilege","summary":"An authenticated Kubernetes tenant can hijack or destroy another tenant's cluster-level RBAC permissions by exploiting namespace ambiguity in Instana Agent Operator.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[],"cvss":{"score":9.6,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"IBM Observability with Instana (Agent) Build 1.0.303 through 1.0.323 IBM Instana Agent Operator could allow an authenticated Kubernetes tenant to hijack or permanently destroy another tenant's cluster-level RBAC permissions, caused by cluster-scoped RBAC objects being keyed solely by the bare CR name with no namespace disambiguation, allowing a same-named `InstanaAgent` CR in an attacker-controlled namespace to silently overwrite the shared `ClusterRoleBinding` or delete it outright and revoke the victim agent's cluster monitoring access.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"IBM Instana Observability is affected by multiple vulnerabilities within Instana Agent container image","id":"CVE-2026-19274","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Stackrox: stackrox: privilege escalation via unanchored regular expressions in auth m2m role mappings","id":"CVE-2026-19278"},"packages":[],"prev":{"headline":"The Dashboard of IBM Sterling B2B Integrator and IBM Sterling File Gateway are Vulnerable to Improper Access Control","id":"CVE-2026-19273"},"products":["Observability with Instana (Agent)"],"published":"2026-09-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-04","vendors":["IBM"]},"summary":"An authenticated Kubernetes tenant can hijack or destroy another tenant's cluster-level RBAC permissions by exploiting namespace ambiguity in Instana Agent Operator.","url":"https://insights.sbomify.com/CVE-2026-19274/"}
