{"id":"EUVD-2026-25060","enisaUuid":"8a1dc60c-4cfe-3b2c-8e02-3f6899a0986a","description":"nimiq-account contains account primitives to be used in Nimiq\u0027s Rust implementation. Prior to version 1.3.0, `VestingContract::can_change_balance` returns `AccountError::InsufficientFunds` when `new_balance \u003c min_cap`, but it constructs the error using `balance: self.balance - min_cap`. `Coin::sub` panics on underflow, so if an attacker can reach a state where `min_cap \u003e balance`, the node crashes while trying to return an error. The `min_cap \u003e balance` precondition is attacker-reachable because the vesting contract creation data (32-byte format) allows encoding `total_amount` without validating `total_amount \u003c\u003d transaction.value` (the real contract balance). After creating such a vesting contract, the attacker can broadcast an outgoing transaction to trigger the panic during mempool admission and block processing. The patch for this vulnerability is included as part of v1.3.0. No known workarounds are available.","datePublished":"Apr 22, 2026, 7:43:04 PM","dateUpdated":"Apr 23, 2026, 4:25:19 PM","baseScore":5.3,"baseScoreVersion":"3.1","baseScoreVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","references":"https://github.com/nimiq/core-rs-albatross/security/advisories/GHSA-vc34-39q2-m6q3\nhttps://github.com/nimiq/core-rs-albatross/pull/3658\nhttps://github.com/nimiq/core-rs-albatross/commit/4d01946f0b3d6c6e31786f91cdfb3eb902908da0\nhttps://github.com/nimiq/core-rs-albatross/releases/tag/v1.3.0\n","aliases":"CVE-2026-34064\n","assigner":"GitHub_M","epss":0.28,"enisaIdProduct":[{"id":"e348e9eb-14e0-3687-a77c-a6fd1caca2e7","product":{"name":"nimiq-account","vendor":{"name":"nimiq"}},"product_version":"\u003c 1.3.0"}],"enisaIdVendor":[{"id":"1f0497f5-2367-3d95-ad22-2a44bcb32732","vendor":{"name":"nimiq"}}],"enisaIdVulnerability":[{"id":"3d993c6c-e5ba-3e1a-a638-a1387c3e1036","vulnerability":{"id":"CVE-2026-34064","description":"nimiq-account contains account primitives to be used in Nimiq\u0027s Rust implementation.
