codeigniter/framework SQL injection in ODBC database driver
Real-World Exposure
codeigniter/frameworkReal-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
CodeIgniter 3.1.0 addressed a critical security issue within the ODBC database driver. This update includes crucial fixes to mitigate a SQL injection vulnerability, preventing potential exploitation by attackers. It is noteworthy that these fixes render the query builder and escape() functions incompatible with the ODBC driver. However, the update introduces actual query binding as a more secure alternative.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for codeigniter/framework, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update codeigniter/framework to 3.1.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-27qr-636m-wxg2 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-27qr-636m-wxg2 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-27qr-636m-wxg2. 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-27qr-636m-wxg2 in your dependencies?
O3 Security finds GHSA-27qr-636m-wxg2 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
