Description
Impact
A user who owns an ENS domain can set a "trapdoor", allowing them to transfer ownership to another user, and later regain ownership without the new owner's consent or awareness.
Patches
A new ENS deployment is being rolled out that fixes this vulnerability in the ENS registry. The registry is newly deployed at 0x00000000000C2E074eC69A0dFb2997BA6C7d2e1e .
Workarounds
Do not accept transfers of ENS domains from other users on the old registrar.

Click to expand
Attack vector (AV:N)
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:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
Service keeps running; no real outage angle.
