CVE-2026-63223CRITICAL | CodeIgniter: Uploaded file extension validation bypass in is_image and mime_in rulesCodeIgniter is a PHP full-stack web framework. Prior to 4.7.4, the is_image and mime_in upload validation rules do not independently enforce a safe client filename extension, allowing a remote attacker to upload executable content when an application preserves the client filename and stores uploads in a web-accessible script-enabled directory. Applications are impacted when they validate uploads using is_image or mime_in without an independent safe extension check (such as ext_in on patched vers… CWE-434Jul 31, 2026 | CVSS9.8v3.1 | EPSS0.493% | PoCs2 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-63222HIGH | CodeIgniter: Path traversal in UploadedFile::move() when using client-provided filenamesCodeIgniter 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. CWE-22Jul 31, 2026 | CVSS7.5v3.1 | EPSS0.45% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-63221CRITICAL | CodeIgniter: SQL injection is possible via Query Builder deleteBatch() when used with where() conditionsCodeIgniter is a PHP full-stack web framework. From 4.3.0 through 4.7.3, Query Builder deleteBatch() substitutes bound values from where() conditions into generated SQL while ignoring their escape flags, allowing user-controlled condition values to be interpreted as SQL. This affects only the deleteBatch() code path. Regular delete() operations escape where() binds correctly. This issue is fixed in version 4.7.4.

CVE-2026-63220MEDIUM | CodeIgniter: Spoofable forwarded HTTPS headers in IncomingRequest::isSecure()CodeIgniter is a PHP full-stack web framework. In versions prior to 4.7.4, IncomingRequest::isSecure() trusted the X-Forwarded-Proto and Front-End-Https headers from any incoming request, allowing an attacker could spoof these headers and cause the application to incorrectly treat an HTTP request as secure. This may have impacted applications that rely on isSecure(), force_https(), forceGlobalSecureRequests, or similar logic to enforce HTTPS-only access or make security-sensitive decisions.

CVE-2026-48062CRITICAL | CodeIgniter: Uploaded file extension validation bypass in `ext_in` ruleCodeIgniter is a PHP full-stack web framework. Prior to 4.7.3, the ext_in upload validation rule in system/Validation/StrictRules/FileRules.php checked the MIME-derived guessed extension instead of the client-provided filename extension. As a result, an uploaded file named shell.php containing GIF-like content could pass validation such as uploaded[avatar]|is_image[avatar]|mime_in[avatar,image/gif]|ext_in[avatar,gif] because the detected MIME type maps to gif, even though the uploaded filename e… CWE-434Jul 17, 2026 | CVSS9.8v3.1 | EPSS0.438% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2025-54418CRITICAL | CodeIgniter4's ImageMagick Handler has Command Injection VulnerabilityCodeIgniter 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 metacharacter… CWE-78Jul 28, 2025 | CVSS9.8v3.1 | EPSS1.49% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2025-24013MEDIUM | CodeIgniter validation of header name and valueCodeIgniter is a PHP full-stack web framework. Prior to 4.5.8, CodeIgniter lacked 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 communic… CWE-436Jan 20, 2025 | CVSS5.3v3.1 | EPSS0.485% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2024-29904HIGH | CodeIgniter4 Language class DoS VulnerabilityCodeIgniter is a PHP full-stack web framework A vulnerability was found in the Language class that allowed DoS attacks.

CVE-2023-46240HIGH | CodeIgniter4 vulnerable to information disclosure when detailed error report is displayed in production environmentCodeIgniter is a PHP full-stack web framework. Prior to CodeIgniter4 version 4.4.3, if an error or exception occurs, a detailed error report is displayed even if in the production environment. As a result, confidential information may be leaked. Version 4.4.3 contains a patch. As a workaround, replace `ini_set('display_errors', '0')` with `ini_set('display_errors', 'Off')` in `app/Config/Boot/production.php`.

CVE-2023-32692CRITICAL | Remote Code Execution Vulnerability in Validation PlaceholdersCodeIgniter is a PHP full-stack web framework. This vulnerability allows attackers to execute arbitrary code when you use Validation Placeholders. The vulnerability exists in the Validation library, and validation methods in the controller and in-model validation are also vulnerable because they use the Validation library internally. This issue is patched in version 4.3.5. CWE-94May 30, 2023 | CVSS9.8v3.1 | EPSS1.13% | PoCs1 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2022-46170HIGH | CodeIgniter is vulnerable to improper authentication via Session HandlersCodeIgniter is a PHP full-stack web framework. When an application uses (1) multiple session cookies (e.g., one for user pages and one for admin pages) and (2) a session handler is set to `DatabaseHandler`, `MemcachedHandler`, or `RedisHandler`, then if an attacker gets one session cookie (e.g., one for user pages), they may be able to access pages that require another session cookie (e.g., for admin pages). This issue has been patched, please upgrade to version 4.2.11 or later. As a workaround… CWE-287Dec 22, 2022 | CVSS8.6v3.1 | EPSS0.841% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2022-23556HIGH | CodeIgniter is vulnerable to IP address spoofing when using proxyCodeIgniter is a PHP full-stack web framework. This vulnerability may allow attackers to spoof their IP address when the server is behind a reverse proxy. This issue has been patched, please upgrade to version 4.2.11 or later, and configure `Config\App::$proxyIPs`. As a workaround, do not use `$request->getIPAddress()`.

Secure or HttpOnly flag set in Config\Cookie is not reflected in Cookies issued in Codeigniter4CodeIgniter is a PHP full-stack web framework. In versions prior to 4.2.7 setting `$secure` or `$httponly` value to `true` in `Config\Cookie` is not reflected in `set_cookie()` or `Response::setCookie()`. As a result cookie values are erroneously exposed to scripts. It should be noted that this vulnerability does not affect session cookies. Users are advised to upgrade to v4.2.7 or later. Users unable to upgrade are advised to manually construct their cookies either by setting the options in cod… | CVSS2.6v3.1 | EPSS0.88% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX | |
CVE-2022-24712MEDIUM | Cross-Site Request Forgery (CSRF) Protection Bypass Vulnerability in CodeIgniter4CodeIgniter4 is the 4.x branch of CodeIgniter, a PHP full-stack web framework. A vulnerability in versions prior to 4.1.9 might allow remote attackers to bypass the CodeIgniter4 Cross-Site Request Forgery (CSRF) protection mechanism. Users should upgrade to version 4.1.9. There are workarounds for this vulnerability, but users will still need to code as these after upgrading to v4.1.9. Otherwise, the CSRF protection may be bypassed. If auto-routing is enabled, check the request method in the con… CWE-352Feb 28, 2022 | CVSS6.3v3.1 | EPSS0.565% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
