The module accepts up to 600 hex characters for the ninth token field but decodes it into a fixed 256-byte buffer with no length check, allowing a maximal input to write up to 44 bytes past the buffer boundary into adjacent esalt fields and heap chunk metadata, potentially enabling heap corruption or memory access violations.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:A/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","score":5.2},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","score":6.1},"cwes":["CWE-122"],"references":["https://github.com/hashcat/hashcat","https://github.com/hashcat/hashcat/commit/6f374c4ff7d5dc951530fbbbcf6b45e3c169b100","https://github.com/hashcat/hashcat/pull/4755","https://www.vulncheck.com/advisories/hashcat-keepass-kdbx-v4-module-heap-buffer-overflow-via-token-field"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:10.689564601+00:00"},"epss":{"cve":"CVE-2026-68765","score":0.0018,"percentile":0.07547,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
