Versions prior to 11.1.11 have a Fastify URL encoding middleware bypass. A NestJS application is vulnerable if it uses `@nestjs/platform-fastify`; relies on `NestMiddleware` (via `MiddlewareConsumer`) for security checks (authentication, authorization, etc.), or through `app.use()`; and applies middleware to specific routes using string paths or controllers (e.g., `.forRoutes('admin')`). Exploitation can result in unauthenticated users accessing protected routes, restricted administrative endpoints becoming accessible to lower-privileged users, and/or middleware performing sanitization or validation being skipped. This issue is patched in `@nestjs/platform-fastify@11.1.11`.","published_at":"2025-12-29T16:01:22.801000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":6.9,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U","cvss_v4_severity":"MEDIUM","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-367"],"nvd_references":["https://github.com/nestjs/nest/security/advisories/GHSA-8wpr-639p-ccrj","https://github.com/nestjs/nest/commit/c4cedda15a05aafec1e6045b36b0335ab850e771"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:28:25.136249Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"P","value_label":"Present"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"N","value_label":"None"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"},{"metric":"E","name":"E","value":"U","value_label":"Unchanged"}]},"affected":[{"vendor_slug":"nestjs","vendor_name":"nestjs","product_slug":"nest","product_name":"nest","version_start":"< 11.1.11","version_start_inclusive":true,"version_end":"< 11.1.11","version_end_inclusive":true,"cpe23_uri":"cve5:nestjs:nest:< 11.1.11:< 11.1.11"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/nestjs/nest/security/advisories/GHSA-8wpr-639p-ccrj","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/nestjs/nest/commit/c4cedda15a05aafec1e6045b36b0335ab850e771","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2025-12-29T16:01:22.801000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:49:26.703903Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:49:26.703903Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:49:26.703903Z","label":"CVSS score revised","source":"cvelistv5"}]}
