Impact
Users of a12nserver that use MySQL might be vulnerable to SQL injection bugs.
If you use a12nserver and MySQL, update as soon as possible. This SQL injection bug might let an attacker obtain OAuth2 Access Tokens for users unrelated to those that permitted OAuth2 clients.
Untrusted input alters a database query, allowing the attacker to read or modify data the query was not intended to access. Typical impact: data disclosure or modification.
GHSA-CRHG-XGRG-VVCC has a CVSS score of 6.5 (Medium). The vector is network-reachable, high 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 (0.23.0); 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-CRHG-XGRG-VVCC? GHSA-CRHG-XGRG-VVCC is a medium-severity SQL injection vulnerability in @curveball/a12n-server (npm), affecting versions >= 0.20.0, < 0.23.0. It is fixed in 0.23.0. Untrusted input alters a database query, allowing the attacker to read or modify data the query was not intended to access.
- How severe is GHSA-CRHG-XGRG-VVCC? GHSA-CRHG-XGRG-VVCC has a CVSS score of 6.5 (Medium). 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 @curveball/a12n-server are affected by GHSA-CRHG-XGRG-VVCC? @curveball/a12n-server (npm) versions >= 0.20.0, < 0.23.0 is affected.
- Is there a fix for GHSA-CRHG-XGRG-VVCC? Yes. GHSA-CRHG-XGRG-VVCC is fixed in 0.23.0. Upgrade to this version or later.
- Is GHSA-CRHG-XGRG-VVCC exploitable, and should I be worried? Whether GHSA-CRHG-XGRG-VVCC 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-CRHG-XGRG-VVCC 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.
- How do I fix GHSA-CRHG-XGRG-VVCC? Upgrade
@curveball/a12n-serverto 0.23.0 or later.
