@angular/core is vulnerable to Cross-site Scripting (XSS)
59
Medium Risk
This Affects:
@angular/coreTL;DR
The Angular runtime allows template and host bindings to attr.on* event-handler attributes to bypass production-mode validation and write attacker-controlled inline handlers into the DOM. When a victim clicks the affected element, the browser executes the injected JavaScript in the application origin. The fix enforces runtime rejection of on* attribute bindings regardless of build mode.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
