GHSA-v42g-7q2x-cw32
CRITICALZendframework1 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.
