DOM clobbering could escalate to Cross-site Scripting (XSS)
CVE-2024-45389 · GHSA-gprj-6m2f-j9hx
- Affected
- crates.io pagefind < 1.1.1
- Fixed in
- 1.1.1· Vendor fix available
- Issue
- Pagefind initializes its dynamic JavaScript and WebAssembly files relative to the location of the first script you load. This information is gathered by looking up the value of document.currentScript.src. It is possible to "clobber" this lookup with otherwise benign HTML on the page, for example: 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 your 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 XSS vector. Pagefind has tightened this resolution by ensuring the source is loaded from a valid script element. There are no reports of this being exploited in the wild via Pagefind.…
Recommended action: Upgrade to 1.1.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
