An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-107805 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/0xJacky/Nginx-UI (Go): affected from 1.9.10-0.20260729084040-acb59fdd81db; fixed in 1.9.10-0.20260901043436-8c9b9a1aff21\n- github.com/0xJacky/Nginx-UI (Go): affected from 1.9.10-0.20260729084040-acb59fdd81db; fixed in 1.9.10-0.20260901043436-8c9b9a1aff21\n- github.com/0xJacky/Nginx-UI (Go): affected from 1.9.10-0.20260729084040-acb59fdd81db; fixed in 1.9.10-0.20260901043436-8c9b9a1aff21\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-2026-107805/ (Markdown: https://insights.sbomify.com/CVE-2026-107805/index.md)","id":"CVE-2026-107805","markdown":"https://insights.sbomify.com/CVE-2026-107805/index.md","name":"CVE-2026-107805","record":{"aliases":["GHSA-j3hg-9rp3-5hw9","GO-2026-6734"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Nginx web UI","requires_auth":"none","summary":"Unauthenticated attackers can exhaust temporary storage and resources in Nginx UI by sending signed requests with large bodies before validation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Nginx UI is a web user interface for the Nginx web server. From 2.5.0 until 2.6.0, the node-signature authentication path performs temporary file staging of an attacker-controlled request body and synchronizes it before validating the body digest and cryptographic signature. An unauthenticated remote client that can reach the API and provide syntactically valid signature metadata can consume temporary filesystem capacity, disk input and output, and request-processing resources before rejection. The issue affects availability and does not bypass authentication or provide confidentiality or integrity impact.
