{"id":"CVE-2026-84203","summary":"Memos 0.26.0 through 0.30.0 Insufficient Session Expiration on Password Change","details":"Memos versions 0.26.0 through 0.30.0 fail to revoke refresh tokens when a user changes their password, allowing attackers to maintain account access. An attacker with a stolen refresh token can call the RefreshToken RPC to obtain new access tokens and rotate the refresh token indefinitely, bypassing the password change security measure.","modified":"2026-09-03T03:48:18.072961013Z","published":"2026-09-01T15:18:58.062Z","database_specific":{"cwe_ids":["CWE-613"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/84xxx/CVE-2026-84203.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/84xxx/CVE-2026-84203.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-84203"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/memos-0.26.0-through-0.30.0-insufficient-session-expiration-on-password-change"},{"type":"PACKAGE","url":"https://github.com/usememos/memos"},{"type":"ARTICLE","url":"https://github.com/usememos/memos/blob/v0.30.0/server/auth/authenticator.go"},{"type":"ARTICLE","url":"https://github.com/usememos/memos/blob/v0.30.0/server/router/api/v1/user_service.go"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/usememos/memos","events":[{"introduced":"1696c6c41428f98c06fcaf8838d43bcbf784c413"},{"fixed":"2036c1ffc1b0a1e1fa6a473738c2a5ef520df67f"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"0.26.0"},{"last_affected":"0.30.0"},{"fixed":"0.30.0"}]}}],"versions":["v0.30.0-rc.2","v0.30.0-rc.1","v0.29.1","v0.29.0","v0.28.0","v0.27.1","v0.27.0","v0.27.0-rc.2","v0.27.0-rc.1","v0.26.2","v0.26.1","v0.26.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-84203.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
