A TempURL signature only covers the method, expiry, and path, and thus the list of disallowed headers is the only defense against a signed PUT request changing what the request does. An attacker holding a PUT TempURL for a single object can add an X-Copy-From header naming any object in the same account; the copy middleware copies that object to the destination, and the attacker then reads the victim's data back with a GET TempURL for the destination object. Copies across account boundaries are rejected. Only deployments using the shipped default proxy pipeline (tempurl and copy middleware) with account-level TempURL keys are affected.","state":0,"publishedAt":"2026-09-24T02:25:49.093+00:00","modifiedAt":"2026-10-06T17:42:19.236+00:00","affected":[{"ecosystem":"Vendor product","name":"Swift","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"product\": \"Swift\",\n                    \"repo\": \"https://opendev.org/openstack/swift\",\n                    \"vendor\": \"OpenStack\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"2.35.5\",\n                            \"status\": \"affected\",\n                            \"version\": \"2.4.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThan\": \"2.36.4\",\n                            \"status\": \"affected\",\n                            \"version\": \"2.36.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThan\": \"2.37.4\",\n                            \"status\": \"affected\",\n                            \"version\": \"2.37.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThan\": \"2.38.2\",\n                            \"status\": \"affected\",\n                            \"version\": \"2.38.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":5.3,"severity":"MEDIUM"}],"references":["https://launchpad.net/bugs/2166876"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-97149","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-97149","identifiers":["CVE-2026-97149"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
