{"id":"CVE-2026-46369","summary":"Nimiq: Validity store off by one error","details":"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.","aliases":["GHSA-3763-qp59-59vf"],"modified":"2026-09-11T03:30:42.893546260Z","published":"2026-08-26T19:32:46.025Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46369.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-193","CWE-294"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46369.json"},{"type":"ADVISORY","url":"https://github.com/nimiq/core-rs-albatross/security/advisories/GHSA-3763-qp59-59vf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46369"},{"type":"FIX","url":"https://github.com/nimiq/core-rs-albatross/commit/a530b2434ebca6e3716f07c73079786fcc6f2e41"},{"type":"FIX","url":"https://github.com/nimiq/core-rs-albatross/pull/3772"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nimiq/core-rs-albatross","events":[{"introduced":"0"},{"fixed":"b661fcf7e7fc1b6bee40d8586ea809780e4cf665"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"1.5.1"}]}}],"versions":["v1.5.0","v1.4.0","v1.3.0","v1.2.2","v1.2.1","v1.2.0","v1.1.1","v1.1.0","v1.0.9","v1.0.8","v1.0.7","v1.0.6","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0.0","v1.0.0-rc.5","v1.0.0-rc.4","v1.0.0-rc.3","v1.0.0-rc.2","v1.0.0-rc.1","v1.0.0-rc.0","v0.24.4","v0.24.3","v0.24.2","v0.24.1","v0.24.0","v0.23.0","v0.22.3","v0.22.2","v0.22.1","v0.22.0","v0.21.1","v0.21.0","v0.20.5","v0.20.4","v0.20.3","v0.20.2","v0.20.1","v0.20.0","v0.19.0","v0.18.0","v0.17.0","v0.16.1","v0.16.0","v0.15.0","v0.14.0","v0.13.1","v0.13.0","v0.12.1","v0.12.0","v0.11.5","v0.11.4","v0.11.3","v0.11.2","v0.11.1","v0.11.0","v0.10.0","v0.9.0","v0.8.3","v0.8.2","v0.8.1","v0.8.0","v0.7.0","v0.6.0","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.1","v0.4.0","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.2.2","v0.2.1","v0.2.0","v0.1.0","v0.1.0-rc.3","v0.1.0-rc.2","v0.1.0-rc.1","v0.1.0-rc.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46369.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:H/A:N"}]}
