Description
When a user edits their profile to change their e-mail address, the system saves it without validating that it actually belongs to the user.
Impact
This could result in storing an invalid email address, preventing the user from receiving system notifications.
Notifications sent to another person's email address could lead to information disclosure.
Patches
Fixed in 2.27.2.
Workarounds
None

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:N)
- Nobody has to click “OK” or open a trap file; it can work without a victim helping.
- Scope (S:U)
- Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
- Confidentiality (C:L)
- 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.
- Availability (A:N)
- Service keeps running; no real outage angle.
