A remote attacker could exploit this vulnerability by sending a specially crafted HTTP/1.1 chunk-size token that includes post-digit whitespace. This incorrect parsing of the chunk size can lead to HTTP request smuggling. This allows an attacker to bypass security controls or access unauthorized resources in proxy/backend deployments.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","cwes":["CWE-444"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:69440","tags":[]},{"url":"https://access.redhat.com/errata/RHSA-2026:69470","tags":[]},{"url":"https://access.redhat.com/security/cve/CVE-2026-93574","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2536966","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
