CVE-2022-3747 | Becustom <= 1.0.5.2 - Cross-Site Request Forgery

Exp

The Becustom plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0.5.2. This is due to missing nonce validation when saving the plugin's settings. This makes it possible for unauthenticated attackers to update the plugin's settings like betheme_url_slug, replaced_theme_author, and betheme_label to name a few, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Base score Version Severity Vector Exploitability Impact Score source
8.8 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H 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:N)
No account or special rights needed—anonymous or random user is enough.
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.
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:H)
Could take the service down hard or make it unusable for people who depend on it.
