Guests can define a long chain of recursive types so that removing the top-level type triggers unbounded recursive drops, exhausting the host stack.","cvssScore":5.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","cwes":["CWE-674"],"vendors":[],"products":[],"references":[{"url":"https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-wjc8-633q-pwxr","tags":[]},{"url":"https://www.vulncheck.com/advisories/wasmtime-42.0.0-before-48.0.6-and-49.0.0-before-49.0.3-stack-overflow-via-type-registry","tags":[]}],"exploitRefs":[{"url":"https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-wjc8-633q-pwxr","tags":[]}],"hasPoc":true,"ai":null}
