Prior to versions 20.3.36, 21.2.23, and 22.1.7, the CommonEngine retrieveSSGPage prerendered-page retrieval logic in @angular/ssr/node, and in @angular/ssr for versions 17 through 18, accepts a relative request URL containing a backslash parent-traversal segment on Windows. The non-special resolve:// URL base preserves the backslash, path.join interprets it as a Windows separator, and the pagePath.startsWith(normalize(publicPath)) check incorrectly accepts a sibling output directory whose name shares the configured public-directory prefix. An unauthenticated requester can therefore retrieve a sibling prerendered HTML page when that page contains the Angular SSG marker. The issue is limited to Windows deployments that pass relative request URLs to CommonEngine.render, have a prefix-sharing sibling output directory, and contain qualifying prerendered Angular HTML; it does not provide arbitrary file read. This issue is fixed in versions 20.3.36, 21.2.23, and 22.1.7.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.3,"severity":null}],"references":["https://github.com/angular/angular-cli/security/advisories/GHSA-7g7c-h8rr-7p6q","https://github.com/angular/angular-cli/commit/645e41a47d21b7651837a4250de99af0509626e2","https://github.com/angular/angular-cli/commit/70748ca8e76fe4b42798719410336119d943e755","https://github.com/angular/angular-cli/commit/bb72145f9ab45aee29f523236b3a25cd0813a841","https://github.com/angular/angular-cli/commit/c3e5982e49705f0f6a913cb94622b4c555d2d914","https://github.com/angular/angular-cli/releases/tag/v20.3.36","https://github.com/angular/angular-cli/releases/tag/v21.2.23","https://github.com/angular/angular-cli/releases/tag/v22.1.7"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-91778","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 2, 2026, 7:43:50 PM","dateUpdated":"Oct 2, 2026, 8:12:49 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
