CVE-2026-22416: 
WordPress vulnerability analysis and mitigation

CVE-2026-22416 is a Local File Inclusion (LFI) vulnerability in the AncoraThemes FixTeam WordPress theme, classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). It affects FixTeam versions up to and including 1.5.0 (with some sources citing through 1.4). The vulnerability was published on March 5, 2026, and assigned by Patchstack. It carries a CVSS v3.1 base score of 8.1 (High) (Feedly, Patchstack).

The root cause is improper control of filenames used in PHP include/require statements (CWE-98), which allows an attacker to manipulate file path parameters and cause the server to include arbitrary local files. Despite being classified under the 'PHP Remote File Inclusion' CWE, the actual attack vector in this case is Local File Inclusion (LFI), meaning an attacker can include files already present on the server's filesystem. Exploitation requires no authentication and no user interaction, though attack complexity is rated High, suggesting specific conditions or non-default configurations must be met. No public proof-of-concept code has been identified at this time (Feedly, Patchstack).

Successful exploitation could allow a remote, unauthenticated attacker to include and execute arbitrary local files on the web server, potentially exposing sensitive configuration files (e.g., wp-config.php), credentials, or other server-side data. In scenarios where file upload functionality is available, LFI can be chained to achieve remote code execution, leading to full system compromise. The vulnerability carries high impacts to confidentiality, integrity, and availability, and could facilitate lateral movement within the hosting infrastructure (Feedly).

As of the time of reporting, there is no public proof-of-concept exploit and no evidence of active in-the-wild exploitation. The EPSS score is approximately 0.053%, indicating a low current probability of exploitation in the near term. The vulnerability is not listed in CISA's Known Exploited Vulnerabilities (KEV) catalog. No threat actor attribution has been reported (Feedly).

Users should update the AncoraThemes FixTeam WordPress theme to a version newer than 1.5.0 as soon as a patched release becomes available. In the interim, consider deactivating or removing the theme if it is not critical to operations. Monitor web server access logs for unusual file path parameters or requests containing directory traversal sequences (e.g., ../). Implement a Web Application Firewall (WAF) rule to block LFI-style request patterns targeting the affected theme (Feedly, Patchstack).

Wordfence noted this vulnerability in their weekly WordPress vulnerability report covering the period of February 23 to March 1, 2026, highlighting it as part of a broader set of WordPress theme and plugin issues. No significant independent researcher commentary or widespread media coverage has been identified beyond standard vulnerability database listings (Wordfence).
