CRITICALDBAL 3 SQL Injection Security Vulnerability
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
We have released a new version Doctrine DBAL 3.1.4 that fixes a critical SQL injection vulnerability in the LIMIT clause generation API provided by the Platform abstraction.
We advise everyone using Doctrine DBAL 3.0.0 up to 3.1.3 to upgrade to 3.1.4 immediately.
The vulnerability can happen when unsanitized input is passed to many APIs in Doctrine DBAL and ORM that ultimately end up calling AbstractPlatform::modifyLimitQuery.
As a workaround you can cast all limit and offset parameters to integers before passing them to Doctrine APIs.
This vulnerability has been assigned CVE-2021-43608.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for doctrine/dbal. 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 doctrine/dbal to 3.1.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r7cj-8hjg-x622 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-r7cj-8hjg-x622 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-r7cj-8hjg-x622. 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-r7cj-8hjg-x622 in your dependencies?
O3 detects GHSA-r7cj-8hjg-x622 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
