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-2025-58084 in the wild and no public exploit code.\n\nAffected product: 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-2025-58084/ (Markdown: https://insights.sbomify.com/CVE-2025-58084/index.md)","id":"CVE-2025-58084","markdown":"https://insights.sbomify.com/CVE-2025-58084/index.md","name":"CVE-2025-58084","record":{"aliases":["GHSA-c8m2-cx6j-jf7p"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mattermost Desktop App","requires_auth":"low_privilege","summary":"An attacker can crash the Mattermost Desktop App by sending a malformed external URL, requiring users to upgrade to a patched version.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mattermost","cpe":[{"product":"mattermost_desktop","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:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-1287","name":"Improper Validation of Specified Type of Input"}],"description":"Mattermost Desktop App versions \u003c= 5.13.0 fail to validate URLs external to the configured Mattermost servers, allowing an attacker on a server the user has configured to crash the user's application by sending the user a malformed URL.","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":"Mattermost Desktop App crashes when clicking on malformed external URL","id":"CVE-2025-58084","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in MedDream PACS Premium","id":"CVE-2025-58087"},"packages":[],"prev":{"headline":"General Industrial Controls Lynx+ Gateway Missing Authentication for Critical Function","id":"CVE-2025-58083"},"products":["Mattermost"],"published":"2025-10-13","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":"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":"2025-10-14","vendors":["Mattermost"]},"summary":"An attacker can crash the Mattermost Desktop App by sending a malformed external URL, requiring users to upgrade to a patched version.","url":"https://insights.sbomify.com/CVE-2025-58084/"}
