CVE-2024-27932 | Deno's improper suffix match testing for DENO_AUTH_TOKENS

Exp

Deno is a JavaScript, TypeScript, and WebAssembly runtime. Starting in version 1.8.0 and prior to version 1.40.4, Deno improperly checks that an import specifier's hostname is equal to or a child of a token's hostname, which can cause tokens to be sent to servers they shouldn't be sent to. An auth token intended for `example[.]com` may be sent to `notexample[.]com`. Anyone who uses DENO_AUTH_TOKENS and imports potentially untrusted code is affected. Version 1.40.0 contains a patch for this issue

Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.

Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
