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.","categories":["Containers & cloud"],"product":"Swift","vendor":"OpenStack","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97149","source_modified_at":"2026-10-06T17:42:19.236Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Swift","vendor":"OpenStack","versions":[{"lessThan":"2.35.5","status":"affected","version":"2.4.0","versionType":"semver"},{"lessThan":"2.36.4","status":"affected","version":"2.36.0","versionType":"semver"},{"lessThan":"2.37.4","status":"affected","version":"2.37.0","versionType":"semver"},{"lessThan":"2.38.2","status":"affected","version":"2.38.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97149","source_modified_at":"2026-10-06T17:42:19.236Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Swift","ecosystem":null},"version":"2.35.5","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97149","source_modified_at":"2026-10-06T17:42:19.236Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Swift","ecosystem":null},"version":"2.36.4","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97149","source_modified_at":"2026-10-06T17:42:19.236Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Swift","ecosystem":null},"version":"2.37.4","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97149","source_modified_at":"2026-10-06T17:42:19.236Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Swift","ecosystem":null},"version":"2.38.2","basis":"first unaffected version stated in the CVE record"}],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00235,"percentile":0.1357,"score_date":"2026-10-23"},"published_at":"2026-09-24T02:25:49.093Z","modified_at":"2026-10-06T17:42:19.236Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97149","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-06T17:42:19.236Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97149","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://launchpad.net/bugs/2166876","tags":["issue-tracking"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-06T15:53:29.868605Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"vendor and product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-06T17:42:19.236Z","content_hash":"acaecdb18995450c781fd4ddfb2b3d8b8f7a7ebe128d46042614a52d77547633"}}
