An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-107812 exists.\n\nAffected packages and fixed versions:\n- github.com/0xJacky/Nginx-UI (Go): affected from 1.9.10-0.20250517140552-daee3ac7ade1; fixed in 1.9.10-0.20260728114330-580585516dd8\n- github.com/0xJacky/Nginx-UI (Go): affected from 1.9.10-0.20250517140552-daee3ac7ade1; fixed in 1.9.10-0.20260728114330-580585516dd8\n- github.com/0xJacky/Nginx-UI (Go): affected from 1.9.10-0.20250517140552-daee3ac7ade1; fixed in 1.9.10-0.20260728114330-580585516dd8\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-2026-107812/ (Markdown: https://insights.sbomify.com/CVE-2026-107812/index.md)","id":"CVE-2026-107812","markdown":"https://insights.sbomify.com/CVE-2026-107812/index.md","name":"CVE-2026-107812","record":{"aliases":["GHSA-662p-52hx-cmh2","GO-2026-6705"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Nginx web UI","requires_auth":"none","summary":"Attackers can execute arbitrary code by compromising the upgrade mirror or performing MITM attacks during self-upgrades due to weak binary verification.","user_interaction":"required","vuln_class":"supply_chain"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"nginx_ui","vendor":"nginxui"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-494","name":"Download of Code Without Integrity Check"}],"description":"Nginx UI is a web user interface for the Nginx web server.

A compromised mirror or network attacker able to alter both responses can supply a malicious executable and matching digest. An operator-triggered upgrade is required, and the application installs and runs the attacker-controlled code in the Nginx UI process context on the next upgrade.
