{"id":"CVE-2026-4324","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-4324","summary":"Katello: Denial of Service and potential information disclosure via SQL injection","details":"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 sort_by parameter of the /api/hosts/bootc_images 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.","published":"2026-03-17T15:36:23Z","modified":"2026-06-01T21:45:26.641319992Z","cvss":{"score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"RubyGems","name":"katello","fixedVersion":"4.19.1"}],"fix":{"url":"https://github.com/Katello/katello/commit/a0a793b08d4f0a897ee985d79a687ad043f99e57","label":"Katello/katello@a0a793b"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-4324"},{"type":"WEB","url":"https://github.com/Katello/katello/commit/a0a793b08d4f0a897ee985d79a687ad043f99e57"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:22326"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:5968"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:5970"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-4324"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2448349"},{"type":"PACKAGE","url":"https://github.com/Katello/katello"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-06-01T21:45:26.641319992Z"}}
