What is CVE-2020-25016?

CVE-2020-25016 is a critical-severity type confusion vulnerability in rgb (rust), affecting versions >= 0.5.4, < 0.8.20. It is fixed in 0.8.20. 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-2020-25016?

CVE-2020-25016 has a CVSS score of 9.1 (Critical). 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 rgb are affected by CVE-2020-25016?

rgb (rust) versions >= 0.5.4, < 0.8.20 is affected.

Is there a fix for CVE-2020-25016?

Yes. CVE-2020-25016 is fixed in 0.8.20. Upgrade to this version or later.

Is CVE-2020-25016 exploitable, and should I be worried?

Whether CVE-2020-25016 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-2020-25016 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

Out of bounds access in rgb

Affected versions of rgb crate allow viewing and modifying data of any type T wrapped in RGB as bytes, and do not correctly constrain RGB and other wrapper structures to the types for which it is safe to do so.

Safety violation possible for a type wrapped in RGB and similar wrapper structures:

If T contains padding, viewing it as bytes may lead to exposure of contents of uninitialized memory.
If T contains a pointer, modifying it as bytes may lead to dereferencing of arbitrary pointers.
Any safety and/or validity invariants for T may be violated.

The issue was resolved by requiring all types wrapped in structures provided by RGB crate to implement an unsafe marker trait.

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-2020-25016 has a CVSS score of 9.1 (Critical). 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 (0.8.20); 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.
