Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-21083 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-2025-21083/ (Markdown: https://insights.sbomify.com/CVE-2025-21083/index.md)","id":"CVE-2025-21083","markdown":"https://insights.sbomify.com/CVE-2025-21083/index.md","name":"CVE-2025-21083","record":{"aliases":["GHSA-h8hh-7xxw-q4pg"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mattermost mobile app","requires_auth":"low_privilege","summary":"A malicious authenticated user can crash the Mattermost mobile app by sending a post with improperly validated properties.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mattermost","cpe":[{"product":"mattermost_mobile","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:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-1287","name":"Improper Validation of Specified Type of Input"}],"description":"Mattermost Mobile Apps versions \u003c=2.22.0 fail to properly validate post props which allows a malicious authenticated user to cause a crash via a malicious 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":"Insufficient Input Validation on Post Props","id":"CVE-2025-21083","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":"Arkcompiler Ets Runtime has an NULL pointer dereference vulnerability","id":"CVE-2025-21084"},"packages":[],"prev":{"headline":"arkui_ace_engine has a type confusion vulnerability","id":"CVE-2025-21082"},"products":["Mattermost"],"published":"2025-01-15","related":[{"cvss_score":7.5,"headline":"Other in n/a","id":"CVE-2019-20848","kev_date_added":null,"published":"2020-06-19"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2019-20852","kev_date_added":null,"published":"2020-06-19"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2020-14449","kev_date_added":null,"published":"2020-06-19"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2020-14451","kev_date_added":null,"published":"2020-06-19"},{"cvss_score":6.5,"headline":"Denial of Service Via Malicious GIF","id":"CVE-2025-1558","kev_date_added":null,"published":"2025-03-24"},{"cvss_score":6.5,"headline":"Mobile crash via improper validation of proto style in attachments","id":"CVE-2025-20072","kev_date_added":null,"published":"2025-01-16"},{"cvss_score":6.5,"headline":"Mobile crash via object that can't be cast to String in Attachment Field","id":"CVE-2025-20630","kev_date_added":null,"published":"2025-01-16"}],"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":"2025-01-15","vendors":["Mattermost"]},"summary":"A malicious authenticated user can crash the Mattermost mobile app by sending a post with improperly validated properties.","url":"https://insights.sbomify.com/CVE-2025-21083/"}
