{"id":"CVE-2025-62370","aliases":["GHSA-pgp9-98jm-wwq2","RUSTSEC-2025-0073"],"url":"https://o3.security/vulnerability/CVE-2025-62370","summary":"Alloy Core has a DoS vulnerability on `alloy_dyn_abi::TypedData` hashing","details":"Alloy Core libraries at the root of the Rust Ethereum ecosystem. Prior to 0.8.26 and 1.4.1, an uncaught panic triggered by malformed input to alloy_dyn_abi::TypedData could lead to a denial-of-service (DoS) via eip712_signing_hash(). Software 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. The 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 and backported to v0.8.26.","published":"2025-10-15T15:32:17.686Z","modified":"2026-07-15T01:48:56.620192080Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"alloy-dyn-abi","fixedVersion":"0.8.26"},{"ecosystem":"crates.io","name":"alloy-dyn-abi","fixedVersion":"1.4.1"}],"fix":{"url":"https://github.com/alloy-rs/core/commit/7823e9af8c20e9fcfb5360f5eafd891c457ebccf","label":"alloy-rs/core@7823e9a"},"references":[{"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":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/62xxx/CVE-2025-62370.json"},{"type":"ADVISORY","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":"ADVISORY","url":"https://rustsec.org/advisories/RUSTSEC-2025-0073.html"},{"type":"FIX","url":"https://github.com/alloy-rs/core/commit/7823e9af8c20e9fcfb5360f5eafd891c457ebccf"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:48:56.620192080Z"}}
