CodeIgniter is a PHP full-stack web framework. A command injection vulnerability present in versions prior to 4.6.2 affects applications that use the ImageMagick handler for image processing (`imagick` as the image library) and either allow file uploads with user-controlled filenames and process uploaded images using the `resize()` method or use the `text()` method with user-controlled text content or options. An attacker can upload a file with a malicious filename containing shell metacharacters that get executed when the image is processed or provide malicious text content or options that get executed when adding text to images Users should upgrade to v4.6.2 or later to receive a patch. As a workaround, switch to the GD image handler (`gd`, the default handler), which is not affected by either vulnerability. For file upload scenarios, instead of using user-provided filenames, generate random names to eliminate the attack vector with `getRandomName()` when using the `move()` method, or use the `store()` method, which automatically generates safe filenames. For text operations, if one must use ImageMagick with user-controlled text, sanitize the input to only allow safe characters and validate/restrict text options.
This vulnerability carries a CRITICAL severity rating with a CVSS v3.1 score of 9.8, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 1 product from codeigniter organizations running these solutions should prioritize assessment and patching.
Reported in 2025, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For codeigniter's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
