{"id":"GHSA-pgp9-98jm-wwq2","summary":"alloy-dyn-abi has DoS vulnerability on `alloy_dyn_abi::TypedData` hashing","details":"### Impact\n\nAn uncaught panic triggered by malformed input to `alloy_dyn_abi::TypedData` could lead to a denial-of-service (DoS) via `eip712_signing_hash()`.\n\nSoftware with high availability requirements such as network services may be particularly impacted. If in use, external auto-restarting mechanisms can partially mitigate the availability issues unless repeated attacks are possible.\n\n### Patches\n\nThe vulnerability was patched by adding a check to ensure the element is not empty before accessing its first element; an error is returned if it is empty. The fix is included in version [`v1.4.1`](https://crates.io/crates/alloy-dyn-abi/1.4.1) and backported to [`v0.8.26`](https://crates.io/crates/alloy-dyn-abi/0.8.26).\n\n### Workarounds\n\nThere is no known workaround that mitigates the vulnerability. Upgrading to a patched version is the recommended course of action.\n\n### Reported by\n\nChristian Reitter & Zeke Mostov from [Turnkey](https://www.turnkey.com/)","aliases":["CVE-2025-62370","RUSTSEC-2025-0073"],"modified":"2025-10-16T07:42:41.400007Z","published":"2025-10-15T17:27:12Z","database_specific":{"github_reviewed_at":"2025-10-15T17:27:12Z","nvd_published_at":"2025-10-15T16:15:36Z","cwe_ids":["CWE-20","CWE-248"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/alloy-rs/core/security/advisories/GHSA-pgp9-98jm-wwq2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-62370"},{"type":"WEB","url":"https://github.com/alloy-rs/core/commit/7823e9af8c20e9fcfb5360f5eafd891c457ebccf"},{"type":"WEB","url":"https://crates.io/crates/alloy-dyn-abi/0.8.26"},{"type":"WEB","url":"https://crates.io/crates/alloy-dyn-abi/1.4.1"},{"type":"PACKAGE","url":"https://github.com/alloy-rs/core"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2025-0073.html"}],"affected":[{"package":{"name":"alloy-dyn-abi","ecosystem":"crates.io","purl":"pkg:cargo/alloy-dyn-abi"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.8.26"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/10/GHSA-pgp9-98jm-wwq2/GHSA-pgp9-98jm-wwq2.json"}},{"package":{"name":"alloy-dyn-abi","ecosystem":"crates.io","purl":"pkg:cargo/alloy-dyn-abi"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.0.0"},{"fixed":"1.4.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/10/GHSA-pgp9-98jm-wwq2/GHSA-pgp9-98jm-wwq2.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
