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."}],"revision":"c85652ead13c139894a07b0f032c9b82cb25b76e234dcebc06611b44df4ffcb9","sources":[{"modifiedAt":1793590115160,"name":"CNA: redhat","retrievedAt":1793592512382,"url":"https://www.cve.org/CVERecord?id=CVE-2026-73198"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793592518379,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-73198"}],"ssvc":{"assessedAt":1787240271867,"automatable":"yes","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Ipa: freeipa: unauthenticated dos in `/ipa/i18n_messages` via unbounded request body read","updatedAt":1793592518379}
