An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-33026 exists.\n\nAffected packages and fixed versions:\n- github.com/0xJacky/Nginx-UI (Go): affected all versions; no fix listed\n- github.com/0xJacky/Nginx-UI (Go): affected all versions; fixed in 1.9.10-0.20260315015203-f61bcec547c0\n- github.com/0xJacky/Nginx-UI (Go): affected all versions; fixed in 1.9.10-0.20260315015203-f61bcec547c0\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-2026-33026/ (Markdown: https://insights.sbomify.com/CVE-2026-33026/index.md)","id":"CVE-2026-33026","markdown":"https://insights.sbomify.com/CVE-2026-33026/index.md","name":"CVE-2026-33026","record":{"aliases":["GHSA-fhh2-gg7w-gwpq","GO-2026-4903"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Nginx web UI","requires_auth":"high_privilege","summary":"Attackers can tamper with encrypted backups to inject malicious configurations during restoration in Nginx UI, potentially leading to code execution.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"nginx_ui","vendor":"nginxui"}],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-354","name":"Improper Validation of Integrity Check Value"},{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"},{"id":"CWE-312","name":"Cleartext Storage of Sensitive Information"}],"description":"Nginx UI is a web user interface for the Nginx web server.
