Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Angular uses a DI container (the "platform injector") to hold request-specific state during server-side rendering. For historical reasons, the container was stored as a JavaScript module-scoped global variable. When multiple requests are processed concurrently, they could inadvertently share or overwrite the global injector state. In practical terms, this can lead to one request responding with data meant for a completely different request, leaking data or tokens included on the rendered page or in response headers. As long as an attacker had network access to send any traffic that received a rendered response, they may have been able to send a large number of requests and then inspect the responses for information leaks. The APIs `bootstrapApplication`, `getPlatform`, and `destroyPlatform` were vulnerable and required SSR-only breaking changes. The issue has been patched in all active release lines as well as in the v21 prerelease. Patched packages include `@angular/platform-server` 21.0.0-next.3, 20.3.0, 19.2.15, and 18.2.14 and `@angular/ssr` 21.0.0-next.3, 20.3.0, 19.2.16, and 18.2.21. Several workarounds are available. Disable SSR via Server Routes or builder options, remove any asynchronous behavior from custom `bootstrap` functions, remove uses of `getPlatform()` in application code, and/or ensure that the server build defines `ngJitMode` as false.

According to its self-reported version number, Angular is 16.0.0 prior to 18.2.14, 19.x prior to 19.2.15 or 20.x prior to 20.3.0. It is, therefore, affected by a race condition vulnerability in @angular/platform-server. The SSR platform injector is stored as a module-scoped global variable, allowing concurrent requests to share or overwrite its state and leading to cross-request data leakage. (CVE-2025-59052)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
