{"cve":"CVE-2025-64766","nvd":{"published":"2025-11-17T22:15:48.993","modified":"2026-10-18T20:10:00.110","status":"Deferred","description":"NixOS's Onlyoffice is a software suite that offers online and offline tools for document editing, collaboration, and management. In versions from 22.11 to before 25.05 and versions before Unstable 25.11, a hard-coded secret was used in the NixOS module for the OnlyOffice document server to protect its file cache. An attacker with knowledge of an existing revision ID could use this secret to obtain a document. In practice, an arbitrary revision ID should be hard to obtain. The primary impact is likely the access to known documents from users with expired access. This issue was resolved in NixOS unstable version 25.11 and version 25.05.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-798"],"references":["https://github.com/NixOS/nixpkgs/commit/8e74d05e3de4ee5ad320cd585a7e0f12a4730869","https://github.com/NixOS/nixpkgs/commit/cec38dec00df26a901eb8b424d53bbb3bcc72eec","https://github.com/NixOS/nixpkgs/pull/462100","https://github.com/NixOS/nixpkgs/pull/462204","https://github.com/NixOS/nixpkgs/security/advisories/GHSA-58m4-5wg3-5g5v"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:16:02.354564667+00:00"},"epss":{"cve":"CVE-2025-64766","score":0.00297,"percentile":0.22179,"date":"2026-10-25"},"kev":null,"osv":[],"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).
