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. This issue is fixed in version 2.6.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400"],"references":["https://github.com/0xJacky/nginx-ui/commit/8c9b9a1aff218ee6c980d047b750e49da3c46796","https://github.com/0xJacky/nginx-ui/releases/tag/v2.6.0","https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-j3hg-9rp3-5hw9"],"products":["nginxui:nginx_ui"],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-107805","score":0.00468,"percentile":0.40218,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-j3hg-9rp3-5hw9","url":"https://osv.dev/vulnerability/GHSA-j3hg-9rp3-5hw9","summary":"Nginx UI: Unauthenticated signed-request body staging can exhaust temporary storage","modified":"2026-10-19T21:40:58.919781212Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":[">=1.9.10-0.20260729084040-acb59fdd81db <1.9.10-0.20260901043436-8c9b9a1aff21"],"fixed":["1.9.10-0.20260901043436-8c9b9a1aff21"]}]},{"id":"GO-2026-6734","url":"https://osv.dev/vulnerability/GO-2026-6734","summary":"Nginx UI: Unauthenticated signed-request body staging can exhaust temporary storage in github.com/0xJacky/Nginx-UI","modified":"2026-10-19T21:31:52.823715419Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":[">=1.9.10-0.20260729084040-acb59fdd81db <1.9.10-0.20260901043436-8c9b9a1aff21"],"fixed":["1.9.10-0.20260901043436-8c9b9a1aff21"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
