GHSA-76w8-mqx4-wjrf
HIGHGHSA-76w8-mqx4-wjrf is a high-severity (CVSS 8.1) vulnerability in doctrine/dbal. O3 Security confirms whether GHSA-76w8-mqx4-wjrf is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

doctrine/dbal🐘doctrine/dbalReal-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 identifier quoting in Doctrine DBAL has a potential security problem when user-input is passed into this function, making the security aspect of this functionality obsolete. If you make use of AbstractPlatform::quoteIdentifier() or Doctrine::quoteIdentifier() please upgrade immediately. The ORM itself does not use identifier quoting in combination with user-input, however we still urge everyone to update to the latest version of DBAL.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | doctrine/dbal | ≥ 2.0.0&&< 2.0.8 | 2.0.8 |

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 2.0.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-76w8-mqx4-wjrf 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-76w8-mqx4-wjrf 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-76w8-mqx4-wjrf. 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-76w8-mqx4-wjrf in your dependencies?
O3 detects GHSA-76w8-mqx4-wjrf across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
