Prior to 1.2, the Express server used express.json() without a size limit, which could allow attackers to send extremely large request bodies. This can cause excessive memory usage, degraded performance, or process crashes, resulting in a Denial of Service (DoS). Any application using the JSON parser without limits and exposed to untrusted clients is affected. The issue is not a flaw in Express itself, but in configuration. This issue is fixed in version 1.2. To work around, consider adding a limit option to the JSON parser, rate limiting at the application or reverse-proxy level, rejecting unusually large requests before parsing, or using a reverse proxy (such as NGINX) to enforce maximum request body sizes.","state":0,"publishedAt":"2025-12-12T08:15:48.367+00:00","modifiedAt":"2026-10-07T20:10:01.97+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":8.7,"severity":"HIGH"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/Aarondoran/servify-express/commit/8dff7f56504b356278d849734ef2050e5cd23b61","https://github.com/Aarondoran/servify-express/releases/tag/V1.2","https://github.com/Aarondoran/servify-express/security/advisories/GHSA-qgc4-8p88-4w7m"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-67731","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-400"],"productCriteria":["cpe:2.3:a:servify-express.js:servify_express:*:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2025-12-12T08:15:48.367","lastModified":"2026-10-07T20:10:01.970"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
