Summary

PgHero Allows Information Disclosure Through EXPLAIN Feature

PgHero before 3.1.0 allows Information Disclosure via EXPLAIN because query results may be present in an error message. (Depending on database user privileges, this may only be information from the database, or may be information from file contents on the database server.)

Impact

CVE-2023-22626 has a CVSS score of 7.5 (High). 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 (3.1.0); upgrading removes the vulnerable code path.

Affected versions

pghero (< 3.1.0)

Security releases

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

  1. What is CVE-2023-22626? CVE-2023-22626 is a high-severity security vulnerability in pghero (rubygems), affecting versions < 3.1.0. It is fixed in 3.1.0.
  2. How severe is CVE-2023-22626? CVE-2023-22626 has a CVSS score of 7.5 (High). 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.
  3. Which versions of pghero are affected by CVE-2023-22626? pghero (rubygems) versions < 3.1.0 is affected.
  4. Is there a fix for CVE-2023-22626? Yes. CVE-2023-22626 is fixed in 3.1.0. Upgrade to this version or later.
  5. Is CVE-2023-22626 exploitable, and should I be worried? Whether CVE-2023-22626 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.

  6. What actually determines whether CVE-2023-22626 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.
  7. How do I fix CVE-2023-22626? Upgrade pghero to 3.1.0 or later.
