An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-86259 exists.\n\nAffected product: THU-MAIC OpenMAIC. 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-2026-86259/ (Markdown: https://insights.sbomify.com/CVE-2026-86259/index.md)","id":"CVE-2026-86259","markdown":"https://insights.sbomify.com/CVE-2026-86259/index.md","name":"CVE-2026-86259","record":{"aliases":["GHSA-6j8v-fv4p-986p","GHSA-9m7h-vh2h-rc3w"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenMAIC web application","requires_auth":"none","summary":"Unauthenticated attackers can exploit SSRF in non-production builds to access cloud metadata and credentials via arbitrary URL parameters.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":9,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:L/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"},{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"OpenMAIC before 1.0.1 skips server-side request forgery validation in non-production builds, allowing unauthenticated attackers to reach cloud instance metadata services.
