proxy

git-pkgs proxy 一个用于软件包注册表的缓存代理。通过在本地缓存构件来加速软件包下载，减少带宽占用并提升可靠性。 版本冷却 大多数供应链攻击都依赖于速度：恶意版本发布后，在任何人察觉之前，几分钟内就会被自动化流水线拉取使用。冷却功能为新发布的版本增加了一段隔离期。启用后，代理会从元数据响应中剔除那些尚未超过可配置时间阈值的版本。 cooldown: default: "3d" hide versions published less than 3 days ago ecosystems: npm: "7d" npm gets a longer window cargo: "0...

Astra Linux – Vulnerability in Squid

Squid is a caching proxy for the web that supports HTTP, HTTPS, FTP, and other protocols. Due to an out-of-bounds write vulnerability when assigning ESI variables, Squid is susceptible to a memory corruption error. This error can lead to a denial-of-service attack...

Astra Linux – Vulnerability in Flask

Flask is a lightweight WSGI web application framework. When all of the following conditions are met, a response containing data intended for one client may be cached and subsequently sent by the proxy to other clients. If the proxy also caches Set-Cookie headers, it may send one client’s session...

Next.js's Middleware / Proxy redirects can be cache-poisoned

Impact Next.js uses the x-nextjs-data request header for internal data requests. On affected versions, an external client could send this header on a normal request to a path handled by middleware that returns a redirect. When that happened, the middleware/proxy could treat the request as a data...
