Prior to @quasar/render-ssr-error 2.2.4 and @quasar/app-vite 3.3.0, renderSSRError() in utils/render-ssr-error/src/index.js used diagnostic data from utils/render-ssr-error/src/env.js to serialize process.env, request headers, and cookies into the HTTP page returned by serve.devError(), while the development server listened on all interfaces by default. Any network-adjacent client that reaches an SSR or SSG render failure through this development-only error path can obtain shell environment secrets. The renderer escaped only one exact lowercase script closing-tag spelling, so case variants and valid closing-tag delimiter variants in reflected diagnostic data could terminate the script element and inject markup; executing the injected code in a developer browser additionally requires the payload to accompany that developer's request. This issue is fixed in @quasar/render-ssr-error 2.2.4 and @quasar/app-vite 3.3.0."
