CVE-2025-53341

Vulnerability

Overview

The Stratus WordPress theme, designed for app, SaaS, and software startup sites, versions up to and including 4.2.5, contains a missing authorization vulnerability. This is a broken access control issue where the theme fails to properly enforce permission checks or nonce tokens on certain functions, allowing attackers to bypass intended security levels [1].

Exploitation

The vulnerability can be exploited without authentication or with minimal privileges, as the access control security levels are incorrectly configured. Attackers can send crafted requests to trigger privileged actions that should be restricted to higher-level users, such as administrators. This type of flaw is commonly used in mass-exploit campaigns targeting thousands of WordPress sites simultaneously [1].

Impact

Successful exploitation allows an attacker to perform unauthorized actions within the affected site, potentially leading to content manipulation, settings changes, or other administrative operations. The CVSS v3 base score is 4.3 (Medium), reflecting the moderate but real risk of privilege escalation or data exposure [1].

Mitigation

The vendor has not released a patched version beyond 4.2.5 at the time of publication. Users are strongly advised to update the theme immediately if a fix becomes available, or to contact the theme developer or hosting provider for assistance. As a workaround, site owners should review and harden access control settings and consider disabling the theme until a patch is applied [1].
