GHSA-x5mq-jjr3-vmx6 Missing validation of header name and value in codeigniter4/framework

• Packagist codeigniter4/framework: < 4.5.8 → fixed in 4.5.8

Impact Lack of proper header validation for its name and value. The potential attacker can construct deliberately malformed headers with `Header` class. This could disrupt application functionality, potentially causing errors or generating invalid HTTP requests. In some cases, these malformed requests might lead to a DoS scenario if a remote service’s web application firewall interprets them as malicious and blocks further communication with the application. Patches Upgrade to v4.5.8 or later. Workarounds Validate HTTP header keys and/or values if using user-supplied values before passing them to `Header` class. Differences from CVE-2023-29197 1. Affected Software: • CVE-2023-29197 specifically addresses a vulnerability in the `guzzlehttp/psr7` library. • The reported issue in this Security Advisory is within the CodeIgniter4 framework and does not depend on or use the `guzzlehttp/psr7` library. 2. Root Cause and Implementation: • The vulnerability reported arises from an issue in the Header class of CodeIgniter4, which is unrelated to the functionality or implementation of `guzzlehttp/psr7`. 3. Scope of Impact: • The vulnerability described in this Security Advisory affects applications built with the CodeIgniter4 framework, which does not use or rely on the `guzzlehttp/psr7` library.
