What is CVE-2026-77770?

The miniOrange 2FA WordPress plugin prior to version 6.3.1 and version 19.3 is susceptible to an authentication bypass vulnerability. This flaw allows unauthenticated users to delete site options via unvalidated transaction inputs. As a consequence, any visitor can potentially remove critical settings, leading to scenarios where administrators are locked out of the dashboard or essential functionalities of the miniOrange 2FA plugin are deactivated. This poses significant risks, as it undermines the integrity and availability of the site's security measures.

Affected Version(s)

miniOrange 2FA 5.3.24 < 6.3.1

miniOrange 2FA 18.0 < 19.3

Exploit Proof of Concept (PoC)
