ID","text":"2526827"}],"notes":[{"category":"description","text":"A flaw was found in the `inets` httpd server, part of Erlang/OTP. The server incorrectly processes HTTP requests that contain both `Transfer-Encoding: chunked` and `Content-Length` headers, failing to reject them or close the connection as required by RFC 9112 §6.1. When `inets` is deployed behind a reverse proxy that prioritizes the `Content-Length` header, a remote attacker can exploit this discrepancy to smuggle malicious requests. This can lead to bypassing access controls, poisoning responses for other users, and circumventing authentication mechanisms enforced by the proxy.","title":"Vulnerability description"},{"category":"summary","text":"OTP: inets: inets: HTTP Request Smuggling allows bypassing security controls","title":"Vulnerability summary"},{"category":"general","text":"The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.","title":"CVSS score applicability"}],"product_status":{"known_affected":["cryostat_4:cryostat/cryostat-storage-rhel9","red_hat_advanced_cluster_management_for_kubernetes_2:rhacm2/volsync-rhel9","red_hat_hardened_images:erlang27.src","red_hat_openshift_dev_spaces:devspaces/traefik-rhel9"]},"references":[{"category":"self","summary":"Canonical URL","url":"https://access.redhat.com/security/cve/CVE-2026-73812"},{"category":"external","summary":"RHBZ#2526827","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2526827"},{"category":"external","summary":"https://www.cve.org/CVERecord?id=CVE-2026-73812","url":"https://www.cve.org/CVERecord?id=CVE-2026-73812"},{"category":"external","summary":"https://nvd.nist.gov/vuln/detail/CVE-2026-73812","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73812"},{"category":"external","summary":"https://cna.erlef.org/cves/CVE-2026-73812.html","url":"https://cna.erlef.org/cves/CVE-2026-73812.html"},{"category":"external","summary":"https://github.com/erlang/otp/commit/591dc00dc99dc2a426167a3b5257c0c94bd45e91","url":"https://github.com/erlang/otp/commit/591dc00dc99dc2a426167a3b5257c0c94bd45e91"},{"category":"external","summary":"https://github.com/erlang/otp/security/advisories/GHSA-7j6m-4ffg-hg46","url":"https://github.com/erlang/otp/security/advisories/GHSA-7j6m-4ffg-hg46"},{"category":"external","summary":"https://osv.dev/vulnerability/EEF-CVE-2026-73812","url":"https://osv.dev/vulnerability/EEF-CVE-2026-73812"}],"release_date":"2026-09-01T14:42:42.374000+00:00","remediations":[{"category":"none_available","details":"Affected","product_ids":["cryostat_4:cryostat/cryostat-storage-rhel9","red_hat_advanced_cluster_management_for_kubernetes_2:rhacm2/volsync-rhel9","red_hat_hardened_images:erlang27.src","red_hat_openshift_dev_spaces:devspaces/traefik-rhel9"]}],"scores":[{"cvss_v3":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"NONE","baseScore":8.2,"baseSeverity":"HIGH","confidentialityImpact":"LOW","integrityImpact":"HIGH","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N","version":"3.1"},"products":["cryostat_4:cryostat/cryostat-storage-rhel9","red_hat_advanced_cluster_management_for_kubernetes_2:rhacm2/volsync-rhel9","red_hat_hardened_images:erlang27.src","red_hat_openshift_dev_spaces:devspaces/traefik-rhel9"]}],"threats":[{"category":"impact","details":"Important","product_ids":["cryostat_4:cryostat/cryostat-storage-rhel9","red_hat_advanced_cluster_management_for_kubernetes_2:rhacm2/volsync-rhel9","red_hat_hardened_images:erlang27.src","red_hat_openshift_dev_spaces:devspaces/traefik-rhel9"]}],"title":"OTP: inets: inets: HTTP Request Smuggling allows bypassing security controls"}]}
