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."}], "metrics": [{"cvssV4_0": {"Automatable": "NOT_DEFINED", "Recovery": "NOT_DEFINED", "Safety": "NOT_DEFINED", "attackComplexity": "LOW", "attackRequirements": "NONE", "attackVector": "NETWORK", "baseScore": 5.3, "baseSeverity": "MEDIUM", "privilegesRequired": "LOW", "providerUrgency": "NOT_DEFINED", "subAvailabilityImpact": "NONE", "subConfidentialityImpact": "NONE", "subIntegrityImpact": "NONE", "userInteraction": "NONE", "valueDensity": "NOT_DEFINED", "vectorString": "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", "version": "4.0", "vulnAvailabilityImpact": "NONE", "vulnConfidentialityImpact": "LOW", "vulnIntegrityImpact": "NONE", "vulnerabilityResponseEffort": "NOT_DEFINED"}, "format": "CVSS", "scenarios": [{"lang": "en", "value": "GENERAL"}]}], "problemTypes": [{"descriptions": [{"cweId": "CWE-184", "description": "CWE-184 Incomplete List of Disallowed Inputs", "lang": "en", "type": "CWE"}]}], "providerMetadata": {"orgId": "8254265b-2729-46b6-b9e3-3dfca2d5bfca", "shortName": "mitre", "dateUpdated": "2026-09-24T02:25:49.093Z"}, "references": [{"tags": ["issue-tracking"], "url": "https://launchpad.net/bugs/2166876"}], "x_generator": {"engine": "CVE-Request-form 0.0.1"}, "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:openstack:swift:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.4.0", "versionEndExcluding": "2.35.5"}, {"vulnerable": true, "criteria": "cpe:2.3:a:openstack:swift:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.36.0", "versionEndExcluding": "2.36.4"}, {"vulnerable": true, "criteria": "cpe:2.3:a:openstack:swift:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.37.0", "versionEndExcluding": "2.37.4"}, {"vulnerable": true, "criteria": "cpe:2.3:a:openstack:swift:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.38.0", "versionEndExcluding": "2.38.2"}]}]}]}, "adp": [{"title": "CVE Program Container", "references": [{"url": "http://www.openwall.com/lists/oss-security/2026/09/24/5"}], "providerMetadata": {"orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2026-09-24T18:09:33.737Z"}}]}}
