### Summary A DOM Clobbering gadget has been discoverd in Astro's client-side router. It can lead to cross-site scripting (XSS) in websites enables Astro's client-side routing and has *stored* attacker-controlled scriptless HTML elements (i.e., `iframe` tags with unsanitized `name` attributes) on the destination pages. ### Details #### Backgrounds DOM Clobbering is a type of code-reuse attack where the attacker first embeds a piece of non-script, seemingly benign HTML markups in the webpage (e.g. through a post or comment) and leverages the gadgets (pieces of js code) living in the existing javascript code to transform it into executable code. More for information about DOM Clobbering, here are some references: [1] https://scnps.co/papers/sp23_domclob.pdf [2] https://research.securitum.com/xss-in-amp4email-dom-clobbering/ #### Gadgets found in Astro We identified a DOM Clobbering gadget in Astro's client-side routing module, specifically in the `<ViewTransitions />` component. ...

### Impact The image optimization feature of Next.js contained a vulnerability which allowed for a potential Denial of Service (DoS) condition which could lead to excessive CPU consumption. **Not affected:** - The `next.config.js` file is configured with `images.unoptimized` set to `true` or `images.loader` set to a non-default value. - The Next.js application is hosted on Vercel. ### Patches This issue was fully patched in Next.js `14.2.7`. We recommend that users upgrade to at least this version. ### Workarounds Ensure that the `next.config.js` file has either `images.unoptimized`, `images.loader` or `images.loaderFile` assigned. #### Credits Brandon Dahler (brandondahler), AWS Dimitrios Vlastaras
