{"apiVersion":"1.0","identifier":"CVE-2026-46369","description":"Nimiq is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Through 1.5.0, the validity store uses a strict lower-bound comparison that expires a stored transaction too early relative to Transaction::is_valid_at, allowing a remote attacker to replay the same signed transaction during a blocks_per_batch minus one block window and cause the sender and recipient balances to be updated twice. This issue is fixed in version 1.5.1.","publishedAt":"2026-08-26T20:17:23","lastModifiedAt":"2026-08-27T17:18:25","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-46369","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","epssProbability":0.00392,"riskScore":0.78,"affectedProduct":"Nimiq","affectedVersions":"<=1.5.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-46369","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-46369","en":"https://www.redsauce.net/en/cves/CVE-2026-46369","fr":"https://www.redsauce.net/fr/cves/CVE-2026-46369","pt":"https://www.redsauce.net/pt/cves/CVE-2026-46369","de":"https://www.redsauce.net/de/cves/CVE-2026-46369","sk":"https://www.redsauce.net/sk/cves/CVE-2026-46369","el":"https://www.redsauce.net/el/cves/CVE-2026-46369"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-46369"}}
