CVE-2026-22419: 
WordPress vulnerability analysis and mitigation

CVE-2026-22419 is a PHP Local File Inclusion (LFI) vulnerability in the AncoraThemes Honor WordPress theme, classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). It affects all versions of the Honor theme up to and including version 2.3. The vulnerability was published on March 5, 2026, and was assigned by Patchstack. It carries a CVSS v3.1 base score of 8.1 (High) (Feedly, Patchstack).

The root cause is improper control of user-supplied filenames used in PHP include/require statements within the Honor theme (CWE-98). An unauthenticated remote attacker can manipulate input parameters that are passed directly into PHP file inclusion functions, causing the server to include and execute arbitrary local files. Exploitation requires high attack complexity, suggesting some precondition such as knowledge of the server's file structure or a specific parameter value, but no authentication or user interaction is needed. No public proof-of-concept or detailed technical write-up has been identified at this time (Feedly, Patchstack).

Successful exploitation could allow an unauthenticated attacker to read sensitive local files (e.g., WordPress wp-config.php containing database credentials), execute arbitrary PHP code by including files with attacker-controlled content, and potentially achieve full server compromise. The vulnerability carries high confidentiality, integrity, and availability impacts, meaning attackers could exfiltrate sensitive data, modify site content, or disrupt service availability. Lateral movement within the hosting infrastructure is also a risk if database credentials or other secrets are exposed (Feedly).

There is currently no public proof-of-concept exploit and no evidence of active in-the-wild exploitation reported for CVE-2026-22419. The EPSS score is approximately 0.053%, indicating a low probability of exploitation in the near term. The vulnerability has not been added to the CISA Known Exploited Vulnerabilities (KEV) catalog. No threat actor attribution has been identified (Feedly).

No official patch has been confirmed for the Honor theme beyond version 2.3 at the time of disclosure. Organizations using the AncoraThemes Honor theme should upgrade to a version beyond 2.3 as soon as one becomes available, or consider replacing the theme with a supported alternative. In the interim, deploying a Web Application Firewall (WAF) to filter malicious file inclusion requests, enforcing least-privilege file system permissions, and disabling PHP remote file inclusion (allow_url_include = Off in php.ini) are recommended mitigations. Monitoring application logs for unusual file inclusion attempts is also advised (Feedly, Patchstack).

The vulnerability was noted in the Wordfence Intelligence Weekly WordPress Vulnerability Report covering the period of February 23 to March 1, 2026, indicating it received standard coverage within the WordPress security community. No significant vendor statements, notable researcher commentary, or broader media coverage has been identified beyond routine vulnerability reporting (Wordfence).
