CVE-2026-4162 | Gravity SMTP <= 2.1.4 - Missing Authorization to Authenticated (Subscriber+) Plugin Uninstall

The Gravity SMTP plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 2.1.4. This is due to the plugin not properly verifying that a user is authorized to perform an action.

NOTE: This vulnerability is also exploitable via a Cross-Site Request Forgery vector.

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:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:L)
