GHSA-JHPW-976M-542J Angular: Cache-Key Ambiguity in HttpTransferCache Leading to Cross-Request Response Reuse and State Poisoning

Angular's HttpTransferCache caches HTTP requests made during Server-Side Rendering SSR so that they can be reused during client-side hydration. During SSR, HttpTransferCache previously generated identical key material for distinct request parameters when repeated values were present because...

Insufficient Verification of Data Authenticity

Overview Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity in the HttpTransferCache used for server-side rendering, which builds the transfer-cache key by joining repeated HttpParams values with commas so that distinct parameter shapes produce the...

CVE-2026-59895

A flaw was found in Hono, a web application framework. The cx function within hono/css improperly handles class names during server-side rendering. This allows an attacker to inject untrusted values into a JSX class attribute, leading to the injection of arbitrary markup. This could result in...

CVE-2026-59896

A flaw was found in Hono, a Web application framework. The hono/jsx component did not properly isolate context values per request during server-side rendering. This allowed data from a different in-flight request to be used after an asynchronous operation in a component. This could lead to...

CVE-2026-53666

A flaw was found in React Router. If an application is configured to allow attacker-supplied input to modify errors during server-side rendering SSR, a remote attacker could trigger unexpected code execution on the client. This execution could lead to an outbound network request, potentially...

CVE-2026-53666

React Router is a router for React. In versions 6.4.0 through 7.17.0, if application code was written in a way that allows attacker-supplied input to overwrite certain aspects of errors caught by the SSR process, then it was possible for an attacker to trigger unexpected constructor execution on...

CVE-2026-59728

Astro is a web framework for content-driven websites. In versions 1.0.0 through 4.0.18, the source.title and enclosure.type item fields in packages/astro-rss/src/index.ts are interpolated directly into XML template strings without XML-character escaping before being parsed by fast-xml-parser. Bot...

CVE-2026-53666 React Router: Arbitrary Constructor Injection via deserializeErrors() in React Router SSR Hydration

React Router is a router for React. In versions 6.4.0 through 7.17.0, if application code was written in a way that allows attacker-supplied input to overwrite certain aspects of errors caught by the SSR process, then it was possible for an attacker to trigger unexpected constructor execution on...

CVE-2026-53666

CVE-2026-53666 affects React Router versions 6.4.0 through 7.17.0 where attacker-supplied input could overwrite parts of errors captured during SSR, enabling arbitrary constructor execution on the client and triggering outbound network requests. This requires specific, unlikely application-layer ...

CVE-2026-59728

CVE-2026-59728 (astrojs/rss) affects Astro versions 1.0.0–4.0.18 where source.title and enclosure.type are interpolated into XML without escaping in packages/astro-rss/src/index.ts, then parsed by fast-xml-parser. This allows an attacker-controlled value to inject arbitrary XML into the generated...
