CVE-2026-46542: CWE-617: Reachable Assertion in nimiq core-rs-albatross
A denial-of-service vulnerability exists in nimiq core-rs-albatross prior to version 1.4.0. The Ed25519PublicKey::delinearize() function calls unwrap() on curve point decompression, which panics if given invalid public key bytes that do not represent a valid point on the Ed25519 curve. This can crash the hosting process. The issue is fixed in version 1.4.0.
AI Analysis
Technical Summary
Nimiq core-rs-albatross versions before 1.4.0 contain a reachable assertion vulnerability (CWE-617) in the Ed25519 multisig delinearization code path. Specifically, Ed25519PublicKey::delinearize() calls unwrap() on the result of curve point decompression, which causes a panic if the input 32-byte public key does not represent a valid Ed25519 curve point. Since Ed25519PublicKey construction only validates the byte length and not curve membership, invalid keys can reach this code path and cause the process to crash, resulting in a denial-of-service condition. This vulnerability has been patched in version 1.4.0.
Potential Impact
An attacker can cause a denial-of-service by supplying invalid Ed25519 public key bytes that trigger a panic in the delinearization function, crashing the hosting process. There is no impact on confidentiality or integrity. The CVSS score is 4.3 (medium severity).
Mitigation Recommendations
Upgrade to nimiq core-rs-albatross version 1.4.0 or later, where this issue has been fixed. Patch status is confirmed by the vendor advisory stating the fix in version 1.4.0.
