Detailsinfo

A vulnerability, which was classified as problematic, was found in CloudCannon pagefind up to 1.1.0. Affected is an unknown code. The manipulation of the argument document.currentScript.src with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. This is going to have an impact on integrity. CVE summarizes:

Pagefind, a fully static search library, initializes its dynamic JavaScript and WebAssembly files relative to the location of the first script the user loads. 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.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2024-45389 since 08/28/2024. The exploitability is told to be easy. It is possible to launch the attack remotely. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1059.007.

Upgrading to version 1.1.1 eliminates this vulnerability.
