CVE-2026-32390

The Nanosoft WordPress theme, developed by linethemes, contains a missing authorization vulnerability (CVE-2026-32390) that falls under the category of broken access control. This flaw exists because certain functions lack proper authentication or nonce token checks, making it possible for unprivileged users to bypass access control restrictions [1].

An attacker does not need elevated privileges to exploit this issue. The vulnerability is triggered through incorrect configuration of access control security levels in the theme, which can be abused remotely from an unauthenticated state. This type of vulnerability is known to be used in mass-exploit campaigns targeting thousands of websites regardless of their traffic or popularity [1].

Successful exploitation allows an attacker to perform actions that should be restricted to higher-privileged users, such as modifying settings or accessing sensitive information that the unprivileged user should not be able to reach. The CVSS v3 base score is 5.4 (Medium), reflecting the moderate but real risk of privilege escalation.

Users are strongly advised to update the Nanosoft theme to version 1.3.2 or later, which contains the necessary access control fixes. Those unable to update should contact their hosting provider or web developer for assistance to mitigate potential exploitation [1].
