mitigate this issue, configure Apache to enforce a request-body limit for the `/ipa/i18n_messages` endpoint. This can be achieved by adding `LimitRequestBody` directive within the Apache configuration for IPA. For example, to limit the request body to 1MB, add `LimitRequestBody 1048576` to the relevant `<Location \"/ipa/i18n_messages\">` block or a broader `/ipa/*` location. A restart of the Apache HTTP Server (`httpd`) service is required for the changes to take effect, which may temporarily impact FreeIPA service availability. If a reverse proxy or load balancer is used, ensure it also enforces an equivalent body-size limit.","source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-73198"}],"references":["https://access.redhat.com/errata/RHSA-2026:70564","https://access.redhat.com/errata/RHSA-2026:72279","https://access.redhat.com/errata/RHSA-2026:82935","https://access.redhat.com/errata/RHSA-2026:83083","https://access.redhat.com/errata/RHSA-2026:83084","https://access.redhat.com/errata/RHSA-2026:83085","https://access.redhat.com/errata/RHSA-2026:83460","https://access.redhat.com/errata/RHSA-2026:83461","https://access.redhat.com/errata/RHSA-2026:89836","https://access.redhat.com/errata/RHSA-2026:93452","https://access.redhat.com/security/cve/CVE-2026-73198","https://bugzilla.redhat.com/show_bug.cgi?id=2472960"],"sources":[{"name":"CVE","id":"CVE-2026-73198","modified":"2026-11-04T23:16:43.146Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-73198"}],"assessments":[{"source":"redhat","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5}],"sourceAffected":[],"observedAt":"2026-11-05T01:48:11.257Z","kev":{"status":"not-listed","checkedAt":"2026-11-05T07:00:31.683Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-11-02T03:35:32.691Z","attemptedAt":"2026-11-02T03:35:32.691Z"},{"source":"GHSA","status":"available","checkedAt":"2026-11-02T03:35:32.687Z","attemptedAt":"2026-11-02T03:35:32.687Z"},{"source":"EUVD","status":"available","checkedAt":"2026-11-02T03:35:32.772Z","attemptedAt":"2026-11-02T03:35:32.772Z"},{"source":"EPSS","status":"available","checkedAt":"2026-11-02T03:35:32.332Z","attemptedAt":"2026-11-02T03:35:32.332Z"}],"evidence":[{"source":"FIRST EPSS","id":"CVE-2026-73198","url":"https://www.first.org/epss/","probability":0.0054,"percentile":0.4542,"date":"2026-11-01","checkedAt":"2026-11-02T03:35:32.332Z"},{"source":"NVD","id":"CVE-2026-73198","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73198","modified":"2026-10-27T10:10:00.240","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","checkedAt":"2026-11-02T03:35:32.691Z"},{"source":"GitHub Advisory Database","id":"GHSA-p44q-gpjc-mgm9","url":"https://github.com/advisories/GHSA-p44q-gpjc-mgm9","modified":"2026-10-26T15:34:20Z","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","checkedAt":"2026-11-02T03:35:32.687Z"},{"source":"ENISA EUVD","id":"EUVD-2026-63244","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-63244","modified":"Oct 26, 2026, 1:27:01 PM","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","checkedAt":"2026-11-02T03:35:32.772Z"}],"aiSummary":{"text":"A remote, unauthenticated attacker can exploit a vulnerability in the `/ipa/i18n_messages` endpoint of FreeIPA by sending an arbitrarily large request body, causing memory exhaustion and a denial of service (DoS) condition.
