About this fork

This repository is a maintained fork of CodeIgniter 3, branched from upstream bcit-ci/CodeIgniter3.1-stable (CI_VERSION = '3.1.13-dev'), with additional PHP 8+ compatibility fixes.

Upstream CodeIgniter 3 is effectively end-of-life: pull requests are no longer being merged and there is no official security page or advisory feed. As a result, newly discovered CodeIgniter 3 vulnerabilities surface only as third-party CVEs / advisories, and they must be patched here manually — no upstream release will fix them.

Because this fork diverges from upstream, treat any advisory affecting CodeIgniter 3 <= 3.1.13 as "assume potentially affected until verified": version-range matching in CVE databases does not know about this fork, so always confirm against the actual code in system/.

Tracking new vulnerabilities (no paid tooling required)

There is no official feed, so we aggregate free sources. Recommended passive alerts:

  1. OpenCVE — https://app.opencve.io — create a free account and subscribe to vendor codeigniter. Emails you when a new CVE is published. Closest equivalent to an official security page.
  2. GitHub Advisory Database — https://github.com/advisories?query=ecosystem%3Acomposer+codeigniter (package codeigniter/framework). Has an RSS feed.
  3. composer audit — if installed via Composer, run in CI to check the locked version against the PHP security advisories database on every push.
  4. Snyk — https://security.snyk.io/package/composer/codeigniter/framework
  5. Exploit-DB / general web search — where researcher advisories (e.g. the Synacktiv XSS) often appear before a CVE is assigned.

When a source flags something new, verify whether the affected code exists in this fork's system/ directory before acting, then patch on a dedicated tasks/ branch.

Known advisories and their status in this fork

Based on a systematic sweep (2026-07-17) of the FriendsOfPHP/PHP Security Advisories DB — the source composer audit uses — and the GitHub Advisory Database entries for codeigniter/framework.

Reminder: version-range matching in CVE databases does not know about this fork. Every new codeigniter/framework advisory should still be verified against the actual system/ code before assuming it does or does not apply.

Reporting a vulnerability

Open a private report or contact the maintainer directly rather than filing a public issue for unpatched flaws. For tracking already-public advisories, label issues security-watch.

About this fork
This repository is a maintained fork of CodeIgniter 3, branched from upstream
bcit-ci/CodeIgniter3.1-stable
(CI_VERSION = '3.1.13-dev'), with additional PHP 8+ compatibility fixes.
Upstream CodeIgniter 3 is effectively end-of-life: pull requests are no longer
being merged and there is no official security page or advisory feed. As a
result, newly discovered CodeIgniter 3 vulnerabilities surface only as third-party
CVEs / advisories, and they must be patched here manually — no upstream release
will fix them.
Because this fork diverges from upstream, treat any advisory affecting CodeIgniter 3
<= 3.1.13 as "assume potentially affected until verified": version-range
matching in CVE databases does not know about this fork, so always confirm against
the actual code in system/.
Tracking new vulnerabilities (no paid tooling required)
There is no official feed, so we aggregate free sources. Recommended passive alerts:
  1. OpenCVE — https://app.opencve.io — create a free account and subscribe to
vendor codeigniter. Emails you when a new CVE is published. Closest equivalent
to an official security page.
  2. GitHub Advisory Database —
https://github.com/advisories?query=ecosystem%3Acomposer+codeigniter
(package codeigniter/framework). Has an RSS feed.
  3. composer audit — if installed via Composer, run in CI to check the locked
version against the PHP security advisories database on every push.
  4. Snyk — https://security.snyk.io/package/composer/codeigniter/framework
  5. Exploit-DB / general web search — where researcher advisories (e.g. the
Synacktiv XSS) often appear before a CVE is assigned.
When a source flags something new, verify whether the affected code exists in this
fork's system/ directory before acting, then patch on a dedicated tasks/ branch.
Known advisories and their status in this fork
Based on a systematic sweep (2026-07-17) of the FriendsOfPHP/PHP Security Advisories

codeigniter/framework.
