This information is gathered by looking up the value of `document.currentScript.src`. Prior to Pagefind version 1.1.1, it is possible to \"clobber\" this lookup with otherwise benign HTML on the page. This will cause `document.currentScript.src` to resolve as an external domain, which will then be used by Pagefind to load dependencies. This exploit would only work in the case that an attacker could inject HTML to a live, hosted, website. In these cases, this would act as a way to escalate the privilege available to an attacker. This assumes they have the ability to add some elements to the page (for example, `img` tags with a `name` attribute), but not others, as adding a `script` to the page would itself be the cross-site scripting vector. Pagefind has tightened this resolution in version 1.1.1 by ensuring the source is loaded from a valid script element. There are no reports of this being exploited in the wild via Pagefind."}, {"lang": "es", "value": "Pagefind, una librer\u00eda de b\u00fasqueda completamente est\u00e1tica, inicializa sus archivos din\u00e1micos de JavaScript y WebAssembly en relaci\u00f3n con la ubicaci\u00f3n del primer script que carga el usuario.
