Summary
Arbitrary Code Injection in mobile-icon-resizer
mobile-icon-resizer resizes large images for use as icons for iOS and Android.
mobile-icon-resizer has a code execution vulnerability in versions before 0.4.3.
mobile-icon-resizer takes an options object as an argument to define the resulting icons as such:
var options = {
config: './config.js'
}
resize(options, function(err){});
config.js would need to be a file on the filesystem and look something like:
var config = {
iOS: {
"images": [
/* iOS image definitions are not vulnerable */
]
},
android: {
"images" : [
{
"baseRatio" : "console.log('Executing script as baseRatio property')",
"folder" : "drawable-ldpi"
},
{
"ratio" : "console.log('Executing script as ratio property')",
"folder" : "drawable-mdpi"
},
/* other android image defintiions ... */
]
}
};
exports = module.exports = config;
The parameters ratio and baseRatio are passed directly to eval(), thus allowing dynamic javascript payloads to be executed.
Impact
Untrusted input is evaluated as executable code within the application's runtime environment. Typical impact: arbitrary code execution within the application's privilege context.
GHSA-MXJR-XMCG-FG7W has a CVSS score of 6.5 (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 (0.4.3); 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-MXJR-XMCG-FG7W? GHSA-MXJR-XMCG-FG7W is a medium-severity code injection vulnerability in mobile-icon-resizer (npm), affecting versions >= 0.2.0, < 0.4.3. It is fixed in 0.4.3. Untrusted input is evaluated as executable code within the application's runtime environment.
- How severe is GHSA-MXJR-XMCG-FG7W? GHSA-MXJR-XMCG-FG7W 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 mobile-icon-resizer are affected by GHSA-MXJR-XMCG-FG7W? mobile-icon-resizer (npm) versions >= 0.2.0, < 0.4.3 is affected.
- Is there a fix for GHSA-MXJR-XMCG-FG7W? Yes. GHSA-MXJR-XMCG-FG7W is fixed in 0.4.3. Upgrade to this version or later.
- Is GHSA-MXJR-XMCG-FG7W exploitable, and should I be worried? Whether GHSA-MXJR-XMCG-FG7W 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-MXJR-XMCG-FG7W 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.
