Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-2792 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-2023-2792/ (Markdown: https://insights.sbomify.com/CVE-2023-2792/index.md)","id":"CVE-2023-2792","markdown":"https://insights.sbomify.com/CVE-2023-2792/index.md","name":"CVE-2023-2792","record":{"aliases":["GHSA-9v8g-3666-2499"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Mattermost chat platform","requires_auth":"low_privilege","summary":"Attackers can leak private channel contents via crafted ephemeral error messages in Mattermost, requiring a patch to prevent unauthorized data access.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mattermost","cpe":[{"product":"mattermost","vendor":"mattermost"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Mattermost fails to sanitize ephemeral error messages, allowing an attacker to obtain arbitrary message contents by a specially crafted /groupmsg command.","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":"Ephemeral messages return private channel contents in permalink previews","id":"CVE-2023-2792","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mattermost:mattermost","products":["mattermost:mattermost"],"type":"information_disclosure","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Stack exhaustion in PreparePostForClientWithEmbedsAndImages","id":"CVE-2023-2793"},"packages":[],"prev":{"headline":"Playbooks lets you edit arbitrary posts","id":"CVE-2023-2791"},"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":"Attackers can leak private channel contents via crafted ephemeral error messages in Mattermost, requiring a patch to prevent unauthorized data access.","url":"https://insights.sbomify.com/CVE-2023-2792/"}
