What is CVE-2024-58253?

CVE-2024-58253 is a low-severity type confusion vulnerability in obfstr (rust), affecting versions < 0.4.4. It is fixed in 0.4.4. An object is accessed using a type that is incompatible with its actual type, causing the runtime to interpret memory incorrectly.

How severe is CVE-2024-58253?

CVE-2024-58253 has a CVSS score of 2.9 (Low). 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 obfstr are affected by CVE-2024-58253?

obfstr (rust) versions < 0.4.4 is affected.

Is there a fix for CVE-2024-58253?

Yes. CVE-2024-58253 is fixed in 0.4.4. Upgrade to this version or later.

Is CVE-2024-58253 exploitable, and should I be worried?

Whether CVE-2024-58253 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-2024-58253 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

obfstr Type Confusion vulnerability

In the obfstr crate before 0.4.4 for Rust, the obfstr! argument type is not restricted to string slices, leading to invalid UTF-8 conversion that produces an invalid value.

Impact

An object is accessed using a type that is incompatible with its actual type, causing the runtime to interpret memory incorrectly. Typical impact: memory safety violations, unexpected behavior, or code execution.

CVE-2024-58253 has a CVSS score of 2.9 (Low). The vector is requires local access, 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 (0.4.4); upgrading removes the vulnerable code path.

Affected versions

obfstr (< 0.4.4)

Security releases

obfstr → 0.4.4 (rust)

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.
