Summary
codeigniter/framework SQL injection in ODBC database driver
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.
Impact
GHSA-27QR-636M-WXG2 has a CVSS score of 10.0 (Critical). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (3.1.0); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is GHSA-27QR-636M-WXG2? GHSA-27QR-636M-WXG2 is a critical-severity security vulnerability in codeigniter/framework (composer), affecting versions < 3.1.0. It is fixed in 3.1.0.
- How severe is GHSA-27QR-636M-WXG2? GHSA-27QR-636M-WXG2 has a CVSS score of 10.0 (Critical). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of codeigniter/framework are affected by GHSA-27QR-636M-WXG2? codeigniter/framework (composer) versions < 3.1.0 is affected.
- Is there a fix for GHSA-27QR-636M-WXG2? Yes. GHSA-27QR-636M-WXG2 is fixed in 3.1.0. Upgrade to this version or later.
- Is GHSA-27QR-636M-WXG2 exploitable, and should I be worried? Whether GHSA-27QR-636M-WXG2 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-27QR-636M-WXG2 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
