CVE-2026-22477 identifies a Local File Inclusion (LFI) vulnerability in the AncoraThemes Felizia WordPress theme, specifically in versions up to 1.3.4. The vulnerability stems from improper control over the filename parameter used in PHP include or require statements. In PHP, these functions are used to incorporate and execute code from other files. When user input is not properly validated or sanitized before being used in these statements, an attacker can manipulate the input to include arbitrary files from the server's filesystem. This can lead to information disclosure, such as reading configuration files, password files, or other sensitive data. In some cases, if combined with other vulnerabilities or misconfigurations, it might allow remote code execution. The vulnerability is classified as a Local File Inclusion rather than Remote File Inclusion, indicating that the attacker can include files already present on the server rather than fetching remote files. The vulnerability was reserved in early January 2026 and published in March 2026, with no CVSS score assigned yet and no known exploits in the wild. The lack of patches at the time of disclosure means users must rely on temporary mitigations. The affected product, Felizia, is a WordPress theme developed by AncoraThemes, which is used to customize website appearance and functionality. Since WordPress is widely deployed globally, any vulnerability in popular themes can have broad impact. The vulnerability's root cause is insufficient input validation in the theme's PHP code that handles file inclusion, a common source of LFI vulnerabilities. Attackers exploiting this flaw could read sensitive files, potentially exposing credentials, configuration details, or other private data. This can facilitate further attacks such as privilege escalation or lateral movement within the compromised environment. The absence of authentication requirements or user interaction details is not explicitly stated, but typical LFI vulnerabilities in themes often do not require authentication, increasing risk. Overall, this vulnerability represents a significant risk to websites using the Felizia theme without patches or mitigations.

The primary impact of CVE-2026-22477 is unauthorized disclosure of sensitive information through Local File Inclusion. Attackers can leverage this to access configuration files, database credentials, or other critical data stored on the server, compromising confidentiality. In some scenarios, this can lead to remote code execution if attackers can include files containing malicious code or exploit chained vulnerabilities, affecting integrity and availability. Organizations running websites with the vulnerable Felizia theme risk data breaches, website defacement, or full system compromise. This can result in reputational damage, regulatory penalties, and operational disruption. Since WordPress powers a significant portion of the web, and themes are widely used, the scope of affected systems is considerable. The ease of exploitation is moderate to high, as LFI vulnerabilities often require only crafted HTTP requests without authentication. The absence of known exploits in the wild currently limits immediate impact but also means attackers may develop exploits soon after disclosure. Overall, the threat poses a high risk to organizations relying on the Felizia theme, especially those with sensitive data or critical web services exposed publicly.

1. Monitor AncoraThemes and official WordPress theme repositories for patches addressing CVE-2026-22477 and apply them promptly once available. 2. In the interim, restrict web server permissions to limit file access, ensuring the web server user cannot read sensitive files outside the web root. 3. Employ web application firewalls (WAFs) with rules designed to detect and block suspicious file inclusion attempts, such as requests containing directory traversal sequences or unusual parameters. 4. Review and harden PHP configuration settings, disabling dangerous functions like allow_url_include and restricting include_path to trusted directories. 5. Conduct code audits on customizations or child themes derived from Felizia to identify and remediate unsafe file inclusion practices. 6. Implement strict input validation and sanitization for any user-supplied parameters involved in file handling. 7. Use security plugins for WordPress that can detect and alert on anomalous behavior related to file inclusion. 8. Maintain regular backups and incident response plans to quickly recover from potential exploitation. 9. Limit administrative access and monitor logs for unusual access patterns that may indicate exploitation attempts. These measures collectively reduce the risk of exploitation until an official patch is released and applied.
