From 46.0.0 until 48.0.7 and 49.0.4, lowering a host-created component-model stream or future into a guest can omit a required payload-type check after the value passes through guest code and returns through StreamAny, FutureAny, Val::Stream, Val::Future, or an equivalent typed reader. A malicious guest that controls exported function types or returned values can cause the host to pass the type-erased value to a guest expecting a different payload type, which panics the Wasmtime host. This issue is fixed in versions 48.0.7 and 49.0.4.\nhttps://www.cve.org/CVERecord?id=CVE-2026-115892https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-9pvw-hwfg-92h5https://github.com/bytecodealliance/wasmtime/pull/14819https://github.com/bytecodealliance/wasmtime/pull/14820https://github.com/bytecodealliance/wasmtime/pull/14827https://github.com/bytecodealliance/wasmtime/commit/222ff3a65dab9aa7011f8c246937751a0bac5abdhttps://github.com/bytecodealliance/wasmtime/commit/48dacc76241f06088e79f3ce1b17642f2f7bf158https://github.com/bytecodealliance/wasmtime/commit/994549891c8a706cb4f2809f9d17b9f67b31e618https://github.com/bytecodealliance/wasmtime/releases/tag/v48.0.7https://github.com/bytecodealliance/wasmtime/releases/tag/v49.0.4#bytecodealliance #wasmtime#CVE_2026_115892#bot", "url": "https://infosec.exchange/users/cve/statuses/117492378466257178"}, {"timestamp": "2026-10-23T22:04:45Z", "date_only": false, "value": "2026-10-23T22:04:45Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-9PVW-HWFG-92H5", "record": "GHSA-9PVW-HWFG-92H5", "field": "published"}, {"timestamp": "2026-10-23T22:04:45Z", "date_only": false, "value": "2026-10-23T22:04:45Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-9PVW-HWFG-92H5", "record": "GHSA-9PVW-HWFG-92H5", "field": "modified"}, {"timestamp": "2026-10-23T22:16:58.633Z", "date_only": false, "value": "2026-10-23T22:16:58.633", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-115892", "record": "FKIE_CVE-2026-115892", "field": "published"}, {"timestamp": "2026-10-23T22:16:58.777Z", "date_only": false, "value": "2026-10-23T22:16:58.777", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-115892", "record": "FKIE_CVE-2026-115892", "field": "lastModified"}, {"timestamp": "2026-10-24T06:25:41Z", "date_only": false, "value": "2026-10-24T06:25:41Z", "kind": "other", "label": "Updated", "source": "osv_rustsec \u00b7 RUSTSEC-2026-0378", "record": "RUSTSEC-2026-0378", "field": "modified"}, {"timestamp": "2026-10-26T00:00:00Z", "date_only": false, "value": "2026-10-26T00:00:00Z", "kind": "milestone", "label": "Published", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2026-115892", "record": "UBUNTU-CVE-2026-115892", "field": "published"}, {"timestamp": "2026-10-26T00:00:00Z", "date_only": false, "value": "2026-10-26T00:00:00Z", "kind": "other", "label": "Updated", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2026-115892", "record": "UBUNTU-CVE-2026-115892", "field": "modified"}]}
