The JaviBola Custom Theme Test plugin for WordPress is vulnerable to Cross-Site Request Forgery...

Description

The JaviBola Custom Theme Test plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.0.5. This is due to missing or incorrect nonce validation on the options page. This makes it possible for unauthenticated attackers to change the site's active theme by modifying the jbct_theme option via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N 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:N)
Doesn’t really leak secrets in a meaningful way.
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.
