Impact
A partial Directory Traversal Vulnerability found in apoc.log.stream function of apoc plugins in Neo4j Graph database.
This issue allows a malicious actor to potentially break out of the expected directory. The impact is limited to sibling directories. For example, userControlled.getCanonicalPath().startsWith("/usr/out") will allow an attacker to access a directory with a name like /usr/outnot.
Input manipulates file paths to reach files outside the intended directory, such as configuration or credential files. Typical impact: unauthorized file read or write outside the intended directory.

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 CVE-2022-37423? CVE-2022-37423 is a medium-severity path traversal vulnerability in org.neo4j.procedure:apoc (maven), affecting versions >= 4.4.0.0, < 4.4.0.8. It is fixed in 4.4.0.8, 4.3.0.7. Input manipulates file paths to reach files outside the intended directory, such as configuration or credential files.
- Which versions of org.neo4j.procedure:apoc are affected by CVE-2022-37423? org.neo4j.procedure:apoc (maven) versions >= 4.4.0.0, < 4.4.0.8 is affected.
- Is there a fix for CVE-2022-37423? Yes. CVE-2022-37423 is fixed in 4.4.0.8, 4.3.0.7. Upgrade to this version or later.
- Is CVE-2022-37423 exploitable, and should I be worried? Whether CVE-2022-37423 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 CVE-2022-37423 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.
