CVE-2026-22476 is a Local File Inclusion (LFI) vulnerability found in the Elated-Themes Etchy WordPress theme, specifically affecting versions up to 1.0. The vulnerability arises from improper control over the filename parameter used in PHP include or require statements, allowing an attacker to manipulate the input to include arbitrary files from the server. This can lead to disclosure of sensitive files such as configuration files, password stores, or other critical data. While the description mentions 'PHP Remote File Inclusion,' the actual issue is Local File Inclusion, meaning the attacker can include files present on the server but not remote files. Exploiting this vulnerability does not require authentication, making it accessible to unauthenticated attackers. Although no known exploits are currently in the wild and no patches have been published, the vulnerability poses a significant risk because it can be leveraged to escalate attacks, including remote code execution when combined with other vulnerabilities or misconfigurations. The vulnerability affects the Etchy theme, which is used by websites built on WordPress, a widely deployed content management system. The lack of a CVSS score indicates that the vulnerability is newly published and not yet fully assessed, but the technical details and nature of the flaw suggest a high severity. The vulnerability was reserved in early 2026 and published shortly thereafter, indicating recent discovery. The absence of official patches means that users must implement manual mitigations or monitor for updates from the vendor.

The primary impact of CVE-2026-22476 is unauthorized disclosure of sensitive information through Local File Inclusion, which can expose configuration files, user data, or other critical resources stored on the server. This compromises confidentiality and may also affect integrity if attackers modify included files or leverage the vulnerability to execute arbitrary code. The vulnerability can lead to website defacement, data leakage, or serve as a foothold for further attacks such as privilege escalation or remote code execution. Organizations using the affected Etchy theme risk reputational damage, data breaches, and potential regulatory penalties if sensitive customer data is exposed. The ease of exploitation without authentication increases the threat level, especially for publicly accessible websites. The scope is limited to websites running the vulnerable theme, but given WordPress's global popularity, the number of affected sites could be substantial. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for future attacks. The vulnerability is particularly impactful for organizations relying on the affected theme for business-critical websites or e-commerce platforms.

1. Immediately audit all WordPress installations to identify usage of the Elated-Themes Etchy theme, especially versions up to 1.0. 2. If possible, disable or remove the Etchy theme until a patch or update is released by the vendor. 3. Implement strict input validation and sanitization on any parameters controlling file inclusion to prevent manipulation. 4. Use PHP configuration directives such as open_basedir to restrict file access to designated directories, limiting the scope of file inclusion. 5. Employ Web Application Firewalls (WAFs) with rules designed to detect and block attempts to exploit LFI vulnerabilities. 6. Monitor server logs and web traffic for suspicious requests that attempt to include files or access sensitive paths. 7. Keep WordPress core, plugins, and themes updated regularly and subscribe to vendor security advisories for timely patching. 8. Consider deploying runtime application self-protection (RASP) tools that can detect and block malicious file inclusion attempts. 9. Educate development and operations teams about secure coding practices related to file inclusion and input handling. 10. Prepare incident response plans to quickly address potential exploitation attempts.
