Vulnerability Details
The CVE-2026-28124 vulnerability is characterized by improper control of filenames in PHP include/require statements. This can lead to local file inclusion vulnerabilities, allowing unauthorized users access to sensitive files within the server. The vulnerability has been assigned a CVSS score of 8.1, indicating a high severity level due to the significant impact it can have on confidentiality, integrity, and availability.
The affected product is the AncoraThemes Notarius theme, specifically versions from n/a through 1.9. The vulnerability was published on March 5, 2026, and is categorized under CWE-98, which denotes improper control of filename for inclusion.
Technical Analysis
The root cause of CVE-2026-28124 lies in the failure to properly validate user input when handling filenames in PHP's include/require statements. This vulnerability allows attackers to craft requests that can manipulate the inclusion of arbitrary files on the server.
The attack vector for this vulnerability is network-based, where attackers can exploit it remotely without needing physical access to the server. The complexity of the attack is assessed as high due to the requirement for specific conditions to be met for successful exploitation.
No privileges are required to exploit this vulnerability, and no user interaction is necessary, making it easier for attackers to exploit it. The impacts on confidentiality, integrity, and availability are all rated as high, indicating that successful exploitation can lead to severe consequences.
Risk & Impact Analysis
The real-world risk associated with CVE-2026-28124 is significant, particularly for organizations utilizing the affected versions of the Notarius theme. With the potential for attackers to execute arbitrary PHP code, the blast radius can extend to sensitive data exposure and system compromise.
Organizations should be aware that failure to address this vulnerability could result in unauthorized access to critical files, leading to data breaches and reputational damage. Given its high severity and potential impact, organizations should address this vulnerability in their priority patch cycle.
The urgency of remediation is underscored by the high CVSS score, which indicates a pressing need for organizations to act. The ongoing assessment of risks should include regular vulnerability scans and a review of security policies to ensure comprehensive protection against potential exploitation.
