Summary
Some CORS middleware allow untrusted origins
Details

Impact

Some CORS middleware (more specifically those created by specifying two or more origin patterns whose hosts share a proper suffix) incorrectly allow some untrusted origins, thereby opening the door to cross-origin attacks from the untrusted origins in question.

For example, specifying origin patterns https://foo.com and https://bar.com (in that order) would yield a middleware that would incorrectly allow untrusted origin https://barfoo.com.

Patches

Patched in v0.9.0.

Workarounds

None.
