Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-50112 in the wild and no public exploit code.\n\nAffected product: Apache Cloudstack. 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-2026-50112/ (Markdown: https://insights.sbomify.com/CVE-2026-50112/index.md)","id":"CVE-2026-50112","markdown":"https://insights.sbomify.com/CVE-2026-50112/index.md","name":"CVE-2026-50112","record":{"aliases":["GHSA-qh8m-g3r9-6vh2"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"CloudStack IaaS platform","requires_auth":"low_privilege","summary":"Authenticated tenants can trigger SSRF and execute arbitrary root commands on KVM hypervisors via malicious metalink templates.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"cloudstack","vendor":"apache"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"},{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"SSRF via Metalink Mirror URL Resolution:\n\nAn authenticated tenant can register a template pointing to an attacker-controlled metalink file containing internal targets.
