ZendFramework potential SQL Injection Vector When Using PDO_MySql

GHSA-qf36-fx9f-232x

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (zendframework/zendframework1 1.11.6, 1.10.9), 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.

Developers using non-ASCII-compatible encodings in conjunction with the MySQL PDO driver of PHP may be vulnerable to SQL injection attacks. Developers using ASCII-compatible encodings like UTF8 or latin1 are not affected by this PHP issue, which is described in more detail here: http://bugs.php.net/bug.php?id=47802 The PHP Group included a feature in PHP 5.3.6+ that allows any character set information to be passed as part of the DSN in PDO to allow both the database as well as the C-level driver to be aware of which charset is in use which is of special importance when PDO's quoting mechanisms are utilized, which Zend Framework also relies on.

# Patch Next advisory brief: GHSA-qf36-fx9f-232x

Advisory: ZendFramework potential SQL Injection Vector When Using PDO_MySql
IDs: GHSA-qf36-fx9f-232x
Record: https://patchnext.com/advisories/ghsa-qf36-fx9f-232x (revision 1, source checked 26 Oct 2026, 14:25 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: zendframework/zendframework1 1.11.6, 1.10.9. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist zendframework/zendframework1: affected >= 1.10.0, < 1.10.9; >= 1.11.0, < 1.11.6; fixed in 1.11.6, 1.10.9

## Suggested inspection (read-only)
- Packagist zendframework/zendframework1: 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 zendframework/zendframework1.
- 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-qf36-fx9f-232x (GitHub-reviewed advisory GHSA-qf36-fx9f-232x lists affected ranges: Packagist zendframework/zendframework1 >=1.10.0 =1.11.0 <1.11.6)

Commands are suggestions: review each one before running it.
