TYPO3 SQL Injection in dbal
Real-World Exposure
typo3/cmsReal-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
A flaw in the database escaping API results in a SQL injection vulnerability when extension dbal is enabled and configured for MySQL passthrough mode in its extension configuration. All queries which use the DatabaseConnection::sql_query are vulnerable, even if arguments were properly escaped with DatabaseConnection::quoteStr beforehand.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for typo3/cms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update typo3/cms to 6.2.18 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9895-53fc-98v2 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-9895-53fc-98v2 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-9895-53fc-98v2. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
