From version 4.1.0 to before version 6.1.0, a session management vulnerability allows previously issued authenticated sessions to remain valid after sensitive account security changes, specifically password reset and password change. As a result, an attacker who has already obtained a valid session cookie can retain access to the account even after the victim changes or resets their password. This weakens account recovery and session security guarantees. This issue has been patched in version 6.1.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","score":7.1},"cwes":["CWE-613"],"references":["https://github.com/knadh/listmonk/commit/db82035d619348949512dafdaf60c86037cafc9e","https://github.com/knadh/listmonk/releases/tag/v6.1.0","https://github.com/knadh/listmonk/security/advisories/GHSA-h5j9-cvrw-v5qh"],"products":["nadh:listmonk"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-34828","score":0.00312,"percentile":0.24114,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-h5j9-cvrw-v5qh","url":"https://osv.dev/vulnerability/GHSA-h5j9-cvrw-v5qh","summary":"listmonk's active sessions remain valid after password reset and password change","modified":"2026-06-25T23:11:03.933056821Z","packages":[{"ecosystem":"Go","name":"github.com/knadh/listmonk","purl":"pkg:golang/github.com/knadh/listmonk","ranges":[">=1.1.1-0.20241028090858-319053dd7a90 <1.1.1-0.20260329113754-1b5e8d38c778"],"fixed":["1.1.1-0.20260329113754-1b5e8d38c778"]}]},{"id":"GO-2026-5414","url":"https://osv.dev/vulnerability/GO-2026-5414","summary":"listmonk's active sessions remain valid after password reset and password change in github.com/knadh/listmonk","modified":"2026-06-25T23:00:16.317746033Z","packages":[{"ecosystem":"Go","name":"github.com/knadh/listmonk","purl":"pkg:golang/github.com/knadh/listmonk","ranges":[">=1.1.1-0.20241028090858-319053dd7a90 <1.1.1-0.20260329113754-1b5e8d38c778"],"fixed":["1.1.1-0.20260329113754-1b5e8d38c778"]}]}],"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).
