codeigniter/framework SQL injection in ODBC database driver

GHSA-27qr-636m-wxg2

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (codeigniter/framework 3.1.0), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

CodeIgniter 3.1.0 addressed a critical security issue within the ODBC database driver. This update includes crucial fixes to mitigate a SQL injection vulnerability, preventing potential exploitation by attackers. It is noteworthy that these fixes render the query builder and escape() functions incompatible with the ODBC driver. However, the update introduces actual query binding as a more secure alternative.

# Patch Next advisory brief: GHSA-27qr-636m-wxg2

Advisory: codeigniter/framework SQL injection in ODBC database driver
IDs: GHSA-27qr-636m-wxg2
Record: https://patchnext.com/advisories/ghsa-27qr-636m-wxg2 (revision 1, source checked 26 Oct 2026, 14:24 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 10.0)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: codeigniter/framework 3.1.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist codeigniter/framework: affected < 3.1.0; fixed in 3.1.0

## Suggested inspection (read-only)
- Packagist codeigniter/framework: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on codeigniter/framework.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-27qr-636m-wxg2 (GitHub-reviewed advisory GHSA-27qr-636m-wxg2 lists affected ranges: Packagist codeigniter/framework >=0 <3.1.0)
