Security: Render only safe urls with Breadcrumbs
Proposal
GlBreadcrumb component should render only secure and valid links. This means that it should prevent javascript://
and other potentially vulnerable links.
- should allow URLs only with the following protocols (http, https, ftp, mailto)
- should take care of encoded URIs
- should render as
span
tag when thehref
is unsafe
GlSafeLinkDirective
can be used for that purpose.
Why
The javascript
links could lead to cross-site scripting bugs. Although we haven't found any real security vulnerabilities specific to GlDropdownItem
yet, but we need to make sure the components are safe by default.
