This allows authenticated users with member-level permissions to bypass system admin restrictions and add or remove users to/from private channels via the playbook run participants feature, even when the 'Manage Members' permission has been explicitly removed. This can lead to unauthorized access to sensitive channel content and allow guest users to gain channel management privileges.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4},"cwes":["CWE-863"],"references":["https://mattermost.com/security-updates"],"products":["mattermost:mattermost_server"],"source":"nvd","synced_at":"2026-10-19T22:03:23.287444849+00:00"},"epss":{"cve":"CVE-2025-46702","score":0.00216,"percentile":0.12139,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-v8fr-vxmw-6mf6","url":"https://osv.dev/vulnerability/GHSA-v8fr-vxmw-6mf6","summary":"Mattermost Incorrect Authorization vulnerability","modified":"2025-07-28T20:42:15.186805Z","packages":[{"ecosystem":"Go","name":"github.com/mattermost/mattermost-server","purl":"pkg:golang/github.com/mattermost/mattermost-server","ranges":["<0.0.0-20250513065225-4ae5d647fb88"],"fixed":["0.0.0-20250513065225-4ae5d647fb88"]},{"ecosystem":"Go","name":"github.com/mattermost/mattermost/server/v8","purl":"pkg:golang/github.com/mattermost/mattermost/server/v8","ranges":["<8.0.0-20250513065225-4ae5d647fb88"],"fixed":["8.0.0-20250513065225-4ae5d647fb88"]},{"ecosystem":"Go","name":"github.com/mattermost/mattermost/server/v8","purl":"pkg:golang/github.com/mattermost/mattermost/server/v8","ranges":[">=9.11.0 <9.11.16"],"fixed":["9.11.16"]},{"ecosystem":"Go","name":"github.com/mattermost/mattermost/server/v8","purl":"pkg:golang/github.com/mattermost/mattermost/server/v8","ranges":[">=10.5.0 <10.5.6"],"fixed":["10.5.6"]},{"ecosystem":"Go","name":"github.com/mattermost/mattermost/server/v8","purl":"pkg:golang/github.com/mattermost/mattermost/server/v8","ranges":[">=10.6.0 <10.6.6"],"fixed":["10.6.6"]},{"ecosystem":"Go","name":"github.com/mattermost/mattermost/server/v8","purl":"pkg:golang/github.com/mattermost/mattermost/server/v8","ranges":[">=10.7.0 <10.7.3"],"fixed":["10.7.3"]},{"ecosystem":"Go","name":"github.com/mattermost/mattermost/server/v8","purl":"pkg:golang/github.com/mattermost/mattermost/server/v8","ranges":[">=10.8.0 <10.8.1"],"fixed":["10.8.1"]}]},{"id":"GO-2025-3796","url":"https://osv.dev/vulnerability/GO-2025-3796","summary":"Mattermost Incorrect Authorization vulnerability in github.com/mattermost/mattermost-server","modified":"2026-03-03T04:57:22.635481Z","packages":[{"ecosystem":"Go","name":"github.com/mattermost/mattermost-server","purl":"pkg:golang/github.com/mattermost/mattermost-server","ranges":["<0.0.0-20250513065225-4ae5d647fb88",">=9.11.0+incompatible <9.11.16+incompatible",">=10.5.0+incompatible <10.5.6+incompatible",">=10.6.0+incompatible <10.6.6+incompatible",">=10.7.0+incompatible <10.7.3+incompatible",">=10.8.0+incompatible <10.8.1+incompatible"],"fixed":["0.0.0-20250513065225-4ae5d647fb88","9.11.16+incompatible","10.5.6+incompatible","10.6.6+incompatible","10.7.3+incompatible","10.8.1+incompatible"]},{"ecosystem":"Go","name":"github.com/mattermost/mattermost-server/v5","purl":"pkg:golang/github.com/mattermost/mattermost-server/v5","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/mattermost/mattermost-server/v6","purl":"pkg:golang/github.com/mattermost/mattermost-server/v6","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/mattermost/mattermost/server/v8","purl":"pkg:golang/github.com/mattermost/mattermost/server/v8","ranges":["<8.0.0-20250513065225-4ae5d647fb88"],"fixed":["8.0.0-20250513065225-4ae5d647fb88"]}]}],"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).
