Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-3613 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mattermost (Bitnami): affected all versions; fixed in 7.8.6, 7.10.3\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-3613/ (Markdown: https://insights.sbomify.com/CVE-2023-3613/index.md)","id":"CVE-2023-3613","markdown":"https://insights.sbomify.com/CVE-2023-3613/index.md","name":"CVE-2023-3613","record":{"aliases":["BIT-mattermost-2023-3613","GHSA-v326-937j-3p86"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Mattermost WelcomeBot plugin","requires_auth":"low_privilege","summary":"The Mattermost WelcomeBot plugin allows guest accounts to be added to channels without proper validation, potentially exposing channel data to unauthorized users.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mattermost","cpe":[{"product":"mattermost_server","vendor":"mattermost"}],"cvss":{"score":3.5,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Mattermost WelcomeBot plugin fails to to validate the membership status when inviting or adding users to channels allowing guest accounts to be added or invited to channels by default.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Guest accounts invited and added to channels by Welcomebot plugin","id":"CVE-2023-3613","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"mattermost:mattermost_server","products":["mattermost:mattermost_server"],"type":"missing_authorization","year":"2023"},"n_packages":1,"n_references":1,"next":{"headline":"Denial of Service via specially crafted gif image","id":"CVE-2023-3614"},"packages":[{"ecosystem":"Bitnami","fixed":["7.8.6","7.10.3"],"introduced":["0","7.9.0"],"last_affected":[],"package":"mattermost","purl":"pkg:bitnami/mattermost","source":"BIT-mattermost-2023-3613"}],"prev":{"headline":"Unprotected WebView access in Govee Home App","id":"CVE-2023-3612"},"products":["Mattermost Plugins"],"published":"2023-07-17","related":[{"cvss_score":9.9,"headline":"Account takeover on OAuth/OpenID-enabled servers","id":"CVE-2025-12419","kev_date_added":null,"published":"2025-11-27"},{"cvss_score":9.9,"headline":"Account Takeover via Code Exchange Endpoint","id":"CVE-2025-12421","kev_date_added":null,"published":"2025-11-27"},{"cvss_score":9.9,"headline":"Path Traversal Leading to RCE by Any Authenticated Mattermost User","id":"CVE-2025-4981","kev_date_added":null,"published":"2025-06-20"},{"cvss_score":9.9,"headline":"Arbitrary file read via block duplication in Mattermost Boards","id":"CVE-2025-20051","kev_date_added":null,"published":"2025-02-24"},{"cvss_score":9.9,"headline":"Arbitrary file read in Mattermost Boards via import \u0026 export board archive","id":"CVE-2025-25279","kev_date_added":null,"published":"2025-02-24"},{"cvss_score":9.8,"headline":"Mattermost Server: Insufficient Password-Reset Link Invalidation","id":"CVE-2016-11074","kev_date_added":null,"published":"2020-06-19"},{"cvss_score":9.8,"headline":"Mattermost Server allows attackers to gain privileges by accessing unintended API endpoints with users' credentials","id":"CVE-2017-18885","kev_date_added":null,"published":"2020-06-19"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-21","vendors":["Mattermost"]},"summary":"The Mattermost WelcomeBot plugin allows guest accounts to be added to channels without proper validation, potentially exposing channel data to unauthorized users.","url":"https://insights.sbomify.com/CVE-2023-3613/"}
