CVE-2026-39637

Vulnerability

Overview

The Mogi WordPress theme, versions from n/a through 1.2.3, suffers from a missing authorization vulnerability. This broken access control issue means that certain functions within the theme lack proper permission checks or nonce tokens, potentially allowing an unprivileged user to execute actions intended for higher-privileged roles [1].

Exploitation

The attack surface is broad because the vulnerability exists in a WordPress theme that, if installed and active, can be exploited over HTTP without requiring prior authentication. Attackers can target arbitrary websites running the affected theme, regardless of their size or traffic, making it suitable for mass-exploit campaigns [1].

Impact

Successful exploitation could allow an attacker to execute arbitrary shortcodes or other higher-privileged actions, potentially leading to content injection, data exposure, or site takeover, depending on the specific missing authorization context [1].

Mitigation

The vendor has not released a patched version beyond 1.2.3; users should either update to the latest available version or, if no update exists, consider disabling the theme or implementing a web application firewall rule as a workaround [1].
