CVE-2021-24328 | WP Login Security and History <= 1.0 - CSRF to Stored Cross-Site Scripting (XSS)

Exp

The WP Login Security and History WordPress plugin through 1.0 did not have CSRF check when saving its settings, not any sanitisation or validation on them. This could allow attackers to make logged in administrators change the plugin's settings to arbitrary values, and set XSS payloads on them as well

6.2 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:N/I:H/A:N Click to expand
Attack vector (AV:N)

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:H)
They need powerful rights—admin, root, or similar—before this pays off.
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: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:N)
Service keeps running; no real outage angle.
