Prior to 1.40.0, CMS.INITBYDIM and CMS.INITBYPROB accept dimensions whose width times depth times sizeof(int64_t) overflows in src/core/cms.cc, allocating an undersized counter buffer while CMS.INCRBY and CMS.QUERY use the unbounded dimensions, which allows an unauthenticated remote client to corrupt or disclose adjacent heap memory and crash the server. This issue is fixed in version 1.40.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.8},"cvss_v3":null,"cwes":["CWE-190"],"references":["https://github.com/dragonflydb/dragonfly/commit/c004623249fe2151dc5d64e21364fb9fb07c90d3","https://github.com/dragonflydb/dragonfly/pull/7647","https://github.com/dragonflydb/dragonfly/releases/tag/v1.40.0","https://github.com/dragonflydb/dragonfly/security/advisories/GHSA-cmmv-h748-v93x","https://github.com/dragonflydb/dragonfly/security/advisories/GHSA-cmmv-h748-v93x"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-62357","score":0.00524,"percentile":0.44136,"date":"2026-10-25"},"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).
