Description
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for zendframework/zendframework1, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update zendframework/zendframework1 to 1.10.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qf36-fx9f-232x is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-qf36-fx9f-232x can be triaged on real exposure rather than presence alone.
Tailored to GHSA-qf36-fx9f-232x. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-qf36-fx9f-232x in your dependencies?
O3 Security finds GHSA-qf36-fx9f-232x across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
