An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-18874 in the wild and no public exploit code.\n\nAffected product: Red Hat Advanced Cluster Management for Kubernetes 2.11. 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-2026-18874/ (Markdown: https://insights.sbomify.com/CVE-2026-18874/index.md)","id":"CVE-2026-18874","markdown":"https://insights.sbomify.com/CVE-2026-18874/index.md","name":"CVE-2026-18874","record":{"aliases":["GHSA-9w6h-ch94-8j27"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["data_modify","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"Red Hat Advanced Cluster Management","requires_auth":"high_privilege","summary":"Attackers can inject malicious YAML into OLM Subscriptions via unescaped annotations, potentially compromising cluster software management.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":6.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"A flaw was found in volsync-addon-controller. This vulnerability allows an attacker to inject malicious YAML (Yet Another Markup Language) code into the OpenShift Lifecycle Manager (OLM) Subscription resource. This is due to improper escaping of annotation values when they are rendered into YAML. Successful exploitation could lead to unauthorized modification or control over OLM Subscription configurations, potentially impacting software management within the cluster.
