GHSA-v42g-7q2x-cw32
CRITICALGHSA-v42g-7q2x-cw32 is a critical-severity (CVSS 9.8) vulnerability in zendframework/zendframework1. O3 Security confirms whether GHSA-v42g-7q2x-cw32 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Zendframework1 potential SQL injection vector using null byte for PDO (MsSql, SQLite)
Blast Radius
zendframework/zendframework1Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
The PDO adapters of Zend Framework 1 do not filter null bytes values in SQL statements. A PDO adapter can treat null bytes in a query as a string terminator, allowing an attacker to add arbitrary SQL following a null byte, and thus create a SQL injection.
We tested and verified the null byte injection using pdo_dblib (FreeTDS) on a Linux environment to access a remote Microsoft SQL Server, and also tested against and noted the vector against pdo_sqlite.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for zendframework/zendframework1. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update zendframework/zendframework1 to 1.12.16 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v42g-7q2x-cw32 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 pinpoints whether GHSA-v42g-7q2x-cw32 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-v42g-7q2x-cw32. 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-v42g-7q2x-cw32 in your dependencies?
O3 detects GHSA-v42g-7q2x-cw32 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
