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-2025-13321 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mattermost-desktop (npm): affected all versions up to 3.6.0; no fix listed\n- mattermost-desktop (npm): affected all versions up to 3.6.0; no fix listed\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-2025-13321/ (Markdown: https://insights.sbomify.com/CVE-2025-13321/index.md)","id":"CVE-2025-13321","markdown":"https://insights.sbomify.com/CVE-2025-13321/index.md","name":"CVE-2025-13321","record":{"aliases":["GHSA-g6qx-wq5w-wr8v"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Mattermost Desktop App","requires_auth":"low_privilege","summary":"Attackers with local system access can read sensitive information from Mattermost Desktop App logs due to insufficient sanitization and data clearing.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mattermost","cpe":[{"product":"mattermost_desktop","vendor":"mattermost"}],"cvss":{"score":3.3,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-532","name":"Insertion of Sensitive Information into Log File"}],"description":"Mattermost Desktop App versions \u003c6.0.0 fail to sanitize sensitive information from Mattermost logs and clear data on server deletion which allows an attacker with access to the users system to gain access to potentially sensitive information via reading the application logs.","ecosystems":["npm"],"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":"Mattermost Desktop App logging sensitive information and fails to clear data on server deletion","id":"CVE-2025-13321","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"information_disclosure","year":"2025"},"n_packages":2,"n_references":1,"next":{"headline":"WP AUDIO GALLERY \u003c= 2.0 - Authenticated (Subscriber+) Arbitrary File Deletion via 'audio_upload' Parameter","id":"CVE-2025-13322"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["3.6.0"],"package":"mattermost-desktop","purl":null,"source":"GHSA-g6qx-wq5w-wr8v"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["3.6.0"],"package":"mattermost-desktop","purl":"pkg:npm/mattermost-desktop","source":"GHSA-g6qx-wq5w-wr8v"}],"prev":{"headline":"WP User Manager \u003c= 2.9.12 - Authenticated (Subscriber+) Arbitrary File Deletion via 'current_user_avatar' Parameter","id":"CVE-2025-13320"},"products":["Mattermost"],"published":"2025-12-17","related":[{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2016-11064","kev_date_added":null,"published":"2020-06-19"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2019-20856","kev_date_added":null,"published":"2020-06-19"},{"cvss_score":8.8,"headline":"Code injection in n/a","id":"CVE-2019-20861","kev_date_added":null,"published":"2020-06-19"},{"cvss_score":7.6,"headline":"Arbitrary application execution via unvalidated server-controlled URLs in Help menu","id":"CVE-2026-1046","kev_date_added":null,"published":"2026-02-16"},{"cvss_score":7.3,"headline":"Security feature bypass in n/a","id":"CVE-2020-14456","kev_date_added":null,"published":"2020-06-19"},{"cvss_score":6.5,"headline":"Posting a malicious markdown image crashes the Mattermost Desktop App","id":"CVE-2026-8075","kev_date_added":null,"published":"2026-07-17"},{"cvss_score":6.5,"headline":"Overly long URLs crash the Mattermost Desktop App","id":"CVE-2026-8683","kev_date_added":null,"published":"2026-06-15"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2025-12-17","vendors":["Mattermost"]},"summary":"Attackers with local system access can read sensitive information from Mattermost Desktop App logs due to insufficient sanitization and data clearing.","url":"https://insights.sbomify.com/CVE-2025-13321/"}
