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-2023-1562 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-2023-1562/ (Markdown: https://insights.sbomify.com/CVE-2023-1562/index.md)","id":"CVE-2023-1562","markdown":"https://insights.sbomify.com/CVE-2023-1562/index.md","name":"CVE-2023-1562","record":{"aliases":["GHSA-w3q2-jmrg-5rfm"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Mattermost collaboration platform","requires_auth":"low_privilege","summary":"An attacker can retrieve the full name of a board owner via an API endpoint that ignores privacy settings, exposing personal information.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mattermost","cpe":[{"product":"mattermost","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-668","name":"Exposure of Resource to Wrong Sphere"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Mattermost fails to check the \"Show Full Name\" setting when rendering the result for the /plugins/focalboard/api/v2/users API call, allowing an attacker to learn the full name of a board owner.","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":"Full name revealed via /plugins/focalboard/api/v2/users","id":"CVE-2023-1562","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":"SourceCodester Student Study Center Desk Management System assign.php sql injection","id":"CVE-2023-1563"},"packages":[],"prev":{"headline":"code-projects Simple Online Hotel Reservation System add_room.php unrestricted upload","id":"CVE-2023-1561"},"products":["Mattermost"],"published":"2023-03-22","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 attacker can retrieve the full name of a board owner via an API endpoint that ignores privacy settings, exposing personal information.","url":"https://insights.sbomify.com/CVE-2023-1562/"}
