Summary
chromedriver Command Injection vulnerability
Versions of the package chromedriver before 119.0.1 are vulnerable to Command Injection when setting the chromedriver.path to an arbitrary system binary. This could lead to unauthorized access and potentially malicious actions on the host system.
Note:
An attacker must have access to the system running the vulnerable chromedriver library to exploit it. The success of exploitation also depends on the permissions and privileges of the process running chromedriver.
Impact
Untrusted input reaches a shell command, allowing arbitrary commands to run on the host. Typical impact: code execution in the application's environment.
CVE-2023-26156 has a CVSS score of 5.6 (Medium). 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 (119.0.1); 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 CVE-2023-26156? CVE-2023-26156 is a medium-severity OS command injection vulnerability in chromedriver (npm), affecting versions < 119.0.1. It is fixed in 119.0.1. Untrusted input reaches a shell command, allowing arbitrary commands to run on the host.
- How severe is CVE-2023-26156? CVE-2023-26156 has a CVSS score of 5.6 (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 chromedriver are affected by CVE-2023-26156? chromedriver (npm) versions < 119.0.1 is affected.
- Is there a fix for CVE-2023-26156? Yes. CVE-2023-26156 is fixed in 119.0.1. Upgrade to this version or later.
- Is CVE-2023-26156 exploitable, and should I be worried? Whether CVE-2023-26156 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-2023-26156 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 CVE-2023-26156? Upgrade
