What is CVE-2023-22799?

CVE-2023-22799 is a low-severity inefficient regular expression (ReDoS) vulnerability in globalid (rubygems), affecting versions >= 0.2.1, < 1.0.1. It is fixed in 1.0.1. A regular expression with worst-case exponential or polynomial matching time is applied to untrusted input, causing excessive CPU use.

Which versions of globalid are affected by CVE-2023-22799?

globalid (rubygems) versions >= 0.2.1, < 1.0.1 is affected.

Is there a fix for CVE-2023-22799?

Yes. CVE-2023-22799 is fixed in 1.0.1. Upgrade to this version or later.

Is CVE-2023-22799 exploitable, and should I be worried?

Whether CVE-2023-22799 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-2023-22799 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

ReDoS based DoS vulnerability in GlobalID

There is a ReDoS based DoS vulnerability in the GlobalID gem. This vulnerability has been assigned the CVE identifier CVE-2023-22799.

Versions Affected: >= 0.2.1 Not affected: NOTAFFECTED Fixed Versions: 1.0.1
Impact

There is a possible DoS vulnerability in the model name parsing section of the GlobalID gem. Carefully crafted input can cause the regular expression engine to take an unexpected amount of time. All users running an affected release should either upgrade or use one of the workarounds immediately.
Releases

The FIXED releases are available at the normal locations.
Workarounds

There are no feasible workarounds for this issue.
Patches

To aid users who aren’t able to upgrade immediately we have provided patches for the two supported release series. They are in git-am format and consist of a single changeset.

1-0-model-name-redos.patch - Patch for 1.0 series

Impact

A regular expression with worst-case exponential or polynomial matching time is applied to untrusted input, causing excessive CPU use. Typical impact: denial of service when input is crafted to trigger backtracking.

Affected versions

globalid (>= 0.2.1, < 1.0.1)

Security releases

globalid → 1.0.1 (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.
