CVE-2026-4324 is a medium-severity SQL injection vulnerability in katello (rubygems), affecting versions < 4.19.1. It is fixed in 4.19.1.
A flaw was found in the Katello plugin for Red Hat Satellite. This vulnerability, caused by improper sanitization of user-provided input, allows a remote attacker to inject arbitrary SQL commands into the sortby parameter of the /api/hosts/bootcimages API endpoint. This can lead to a Denial of Service (DoS) by triggering database errors, and potentially enable Boolean-based Blind SQL injection, which could allow an attacker to extract sensitive information from the database.
Untrusted input alters a database query, allowing the attacker to read or modify data the query was not intended to access. Typical impact: data disclosure or modification.
CVE-2026-4324 has a CVSS score of 5.4 (Medium). The vector is network-reachable, low 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 (4.19.1). Upgrading removes the vulnerable code path.
rubygems
katello (< 4.19.1)katello → 4.19.1 (rubygems)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 instead of chasing every advisory.
Kodem's runtime-powered SCA identifies whether CVE-2026-4324 is reachable in your applications. Explore open-source security for your team.

CVE-2026-4324 is a medium-severity SQL injection vulnerability in katello (rubygems), affecting versions < 4.19.1. It is fixed in 4.19.1. Untrusted input alters a database query, allowing the attacker to read or modify data the query was not intended to access.
CVE-2026-4324 has a CVSS score of 5.4 (Medium). 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.
katello (rubygems) versions < 4.19.1 is affected.
Yes. CVE-2026-4324 is fixed in 4.19.1. Upgrade to this version or later.
Whether CVE-2026-4324 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.

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.
Upgrade katello to 4.19.1 or later.
