What is CVE-2023-46035?

CVE-2023-46035 is a medium-severity XML external entity injection (XXE) vulnerability in svg_optimizer (rubygems), affecting versions = 0.2.6. It is fixed in 0.3.0. An XML parser processes external entity references in untrusted input, causing the server to fetch internal resources or remote URLs.

Which versions of svg_optimizer are affected by CVE-2023-46035?

svg_optimizer (rubygems) versions = 0.2.6 is affected.

Is there a fix for CVE-2023-46035?

Yes. CVE-2023-46035 is fixed in 0.3.0. Upgrade to this version or later.

Is CVE-2023-46035 exploitable, and should I be worried?

Whether CVE-2023-46035 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-2023-46035 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.

Summary

svg_optimizer rubygem external XML entity (XXE) vulnerability

An issue in Fnando svg_optimizer v.0.2.6 allows a remote attacker to escalate privileges when optimizing untrusted SVG content.

Impact

An XML parser processes external entity references in untrusted input, causing the server to fetch internal resources or remote URLs. Typical impact: local file disclosure, server-side request forgery, or denial of service.

Affected versions

svg_optimizer (= 0.2.6)

Security releases

svg_optimizer → 0.3.0 (rubygems)

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.
