The Prototype (prototypejs) framework before 1.5.1 RC3 exchanges data using JavaScript Object Notation (JSON) without an associated protection scheme, which allows remote attackers to obtain the data via a web page that retrieves the data through a URL in the SRC attribute of a SCRIPT element and captures the data using other JavaScript code, aka "JavaScript Hijacking."

Security readout for executives and security teams

CVE-2007-2383 is an old data-exposure issue in Prototype/prototypejs before 1.5.1 RC3. Applications using affected JSON patterns could let another website read data intended for a logged-in user through JavaScript Hijacking. Business impact depends on whether sensitive authenticated JSON responses are exposed. Exposure is most likely in legacy web applications that still bundle Prototype/prototypejs before 1.5.1 RC3 and serve sensitive JSON to authenticated browsers. The affected product metadata in the bundle is incomplete, so validation must rely on asset and dependency inventory. Prioritize if legacy applications still use Prototype and expose sensitive authenticated JSON. This is not KEV-listed in the supplied bundle, so urgency should be driven by confirmed exposure, data sensitivity, and whether the application is internet-facing. Mitigation focus: Inventory Prototype/prototypejs usage and remove versions before 1.5.1 RC3.; Follow Prototype, Rails, Debian, or application vendor guidance for fixed packages.; Avoid returning sensitive authenticated data through unprotected JSON endpoints..
