Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-2791 in the wild and no public exploit code.\n\nAffected product: Mattermost Mattermost. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2023-2791/ (Markdown: https://insights.sbomify.com/CVE-2023-2791/index.md)","id":"CVE-2023-2791","markdown":"https://insights.sbomify.com/CVE-2023-2791/index.md","name":"CVE-2023-2791","record":{"aliases":["GHSA-m9m2-f9hg-rh66"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Mattermost chat platform","requires_auth":"low_privilege","summary":"An authenticated attacker can edit arbitrary channel posts in Mattermost due to insufficient parameter validation in the playbook run API.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mattermost","cpe":[{"product":"mattermost","vendor":"mattermost"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"When creating a playbook run via the /dialog API, Mattermost fails to validate all parameters, allowing an authenticated attacker to edit an arbitrary channel post.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Playbooks lets you edit arbitrary posts","id":"CVE-2023-2791","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mattermost:mattermost","products":["mattermost:mattermost"],"type":"missing_authorization","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Ephemeral messages return private channel contents in permalink previews","id":"CVE-2023-2792"},"packages":[],"prev":{"headline":"TOTOLINK N200RE Telnet Service custom.conf password in configuration file","id":"CVE-2023-2790"},"products":["Mattermost"],"published":"2023-06-16","related":[{"cvss_score":9.1,"headline":"Path traversal in n/a","id":"CVE-2019-20851","kev_date_added":null,"published":"2020-06-19"},{"cvss_score":8.7,"headline":"Malicious remote can add users to arbitrary teams and channels","id":"CVE-2024-39274","kev_date_added":null,"published":"2024-08-01"},{"cvss_score":8.7,"headline":"Malicious remote can invite itself to an arbitrary local channel","id":"CVE-2024-39777","kev_date_added":null,"published":"2024-08-01"},{"cvss_score":8.1,"headline":"Timing attack during remote cluster token comparison when shared channels are enabled","id":"CVE-2024-39830","kev_date_added":null,"published":"2024-07-03"},{"cvss_score":8.1,"headline":"Lack of server certificate validation in websockets connection","id":"CVE-2023-3615","kev_date_added":null,"published":"2023-07-17"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2020-13891","kev_date_added":null,"published":"2020-06-26"},{"cvss_score":7.4,"headline":"Existing local user overwritten by malicious remote","id":"CVE-2024-36492","kev_date_added":null,"published":"2024-08-01"}],"sources":[{"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":"2024-12-06","vendors":["Mattermost"]},"summary":"An authenticated attacker can edit arbitrary channel posts in Mattermost due to insufficient parameter validation in the playbook run API.","url":"https://insights.sbomify.com/CVE-2023-2791/"}
