It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-3581 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mattermost (Bitnami): affected from 7.8.0; fixed in 7.8.7, 7.9.5, 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-2023-3581/ (Markdown: https://insights.sbomify.com/CVE-2023-3581/index.md)","id":"CVE-2023-3581","markdown":"https://insights.sbomify.com/CVE-2023-3581/index.md","name":"CVE-2023-3581","record":{"aliases":["BIT-mattermost-2023-3581","GHSA-5g2h-c436-5ppg"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Mattermost chat platform","requires_auth":"high_privilege","summary":"A Man-in-the-Middle attacker can bypass origin validation to access Mattermost WebSocket APIs, potentially reading or modifying data.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mattermost","cpe":[{"product":"mattermost_server","vendor":"mattermost"}],"cvss":{"score":6.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"}],"description":"Mattermost fails to properly validate the origin of a websocket connection allowing a MITM attacker on Mattermost to access the websocket APIs.","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":"WebSockets accept connections from HTTPS origin","id":"CVE-2023-3581","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"mattermost:mattermost_server","products":["mattermost:mattermost_server"],"type":"security_feature_bypass","year":"2023"},"n_packages":1,"n_references":1,"next":{"headline":"Lack of channel membership check when linking a board to a channel","id":"CVE-2023-3582"},"packages":[{"ecosystem":"Bitnami","fixed":["7.8.7","7.9.5","7.10.3"],"introduced":["7.8.0","7.9.0","7.10.0"],"last_affected":[],"package":"mattermost","purl":"pkg:bitnami/mattermost","source":"BIT-mattermost-2023-3581"}],"prev":{"headline":"Improper Handling of Additional Special Element in squidex/squidex","id":"CVE-2023-3580"},"products":["Mattermost"],"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":"total"},"state":"PUBLISHED","updated":"2024-10-30","vendors":["Mattermost"]},"summary":"A Man-in-the-Middle attacker can bypass origin validation to access Mattermost WebSocket APIs, potentially reading or modifying data.","url":"https://insights.sbomify.com/CVE-2023-3581/"}
