NOTE: the vendor disputes this for two reasons: the information is inherently available during a logged-in session when the attacker can read from arbitrary memory locations, and information only remains available after logout because of memory-management limitations of web browsers (not because the Keeper technology itself is retaining the information).","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":5.5},"cwes":["CWE-522"],"references":["http://packetstormsecurity.com/files/173809/Keeper-Security-Desktop-16.10.2-Browser-Extension-16.5.4-Password-Dumper.html","https://docs.keeper.io/en/enterprise-guide/keeper-forcefield","https://docs.keeper.io/en/release-notes/desktop/web-vault-+-desktop-app/vault-release-17.2","https://harkenzo.tlstickle.com/2023-06-12-Keeper-Password-Dumping/","http://packetstormsecurity.com/files/173809/Keeper-Security-Desktop-16.10.2-Browser-Extension-16.5.4-Password-Dumper.html"],"products":["keepersecurity:keeper","keepersecurity:keeperfill"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-36266","score":0.00781,"percentile":0.55965,"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).
