Low risk37th percentile - higher than 37% of all known CVEs
Summary
CodeIgniter prior to version 4.7.4 is vulnerable in the UploadedFile::move() method. Calling it without a second argument uses the client-provided filename without sanitization, allowing a remote attacker to use path traversal sequences to write uploaded content outside the intended directory.
Risk Assessment
An attacker can write files to arbitrary locations on the server, potentially leading to code execution or overwriting critical files.
Recommendation
Update CodeIgniter to version 4.7.4 or later.
Other vulnerabilities in CodeIgniter
See all- CVE-2017-1000247High
CodeIgniter version 3.1.3, used by the British Columbia Institute of Technology, is vulnerable to HTTP Header Injection in the set_status_header() function under Apache, leading to HTTP Header Injection flaws.
- CVE-2026-63223Critical
CodeIgniter prior to 4.7.4 has a vulnerability in the is_image and mime_in upload validation rules that do not enforce a safe client filename extension. A remote attacker can upload executable content if the application preserves the client filename and stores uploads in a web-accessible script-enabled directory.
- CVE-2026-63221Critical
CodeIgniter from 4.3.0 through 4.7.3 has a vulnerability in the Query Builder deleteBatch() method that substitutes bound values from where() conditions into generated SQL while ignoring their escape flags, allowing SQL injection.
- CVE-2026-48062Critical
CodeIgniter before version 4.7.3 contains a vulnerability in the ext_in validation rule, which checks the extension based on the detected MIME type rather than the actual file extension. A file named shell.php with GIF content can pass validation, potentially leading to arbitrary code execution.
- CVE-2014-8686Critical
CodeIgniter before 2.2.0 makes it easier for attackers to decode session cookies by leveraging fallback to a custom XOR-based encryption scheme when the Mcrypt extension for PHP is not available.
- CVE-2026-63220Medium
In CodeIgniter before version 4.7.4, IncomingRequest::isSecure() trusts X-Forwarded-Proto and Front-End-Https headers, allowing an attacker to spoof them and cause the application to incorrectly treat an HTTP request as secure, potentially affecting HTTPS enforcement logic.
Original NVD description (English source)
CodeIgniter is a PHP full-stack web framework. Prior to 4.7.4, calling UploadedFile::move() without a second argument uses the client-provided filename without sanitization, allowing a remote attacker to use path traversal sequences to write uploaded content outside the intended directory when the application exposes an upload path. This issue is fixed in version 4.7.4.
