An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-59480 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-2025-59480/ (Markdown: https://insights.sbomify.com/CVE-2025-59480/index.md)","id":"CVE-2025-59480","markdown":"https://insights.sbomify.com/CVE-2025-59480/index.md","name":"CVE-2025-59480","record":{"aliases":["GHSA-h2fg-6x82-5f24"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Mattermost mobile app","requires_auth":"none","summary":"Attackers can steal user session credentials by exploiting inadequate validation of SSO redirect tokens in the Mattermost mobile application.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mattermost","cpe":[{"product":"mattermost_mobile","vendor":"mattermost"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Mattermost Mobile Apps versions \u003c=2.32.0 fail to verify that SSO redirect tokens originate from the trusted server, which allows a malicious Mattermost instance or on-path attacker to obtain user session credentials via crafted token-in-URL responses","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":"Inadequate validation of SSO redirect credentials permits credential theft","id":"CVE-2025-59480","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"open_redirect","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"BIG-IP iControl REST and tmsh vulnerability","id":"CVE-2025-59481"},"packages":[],"prev":{"headline":"Cross-site request forgery in CHOCO TEI WATCHER mini (IB-MCT001)","id":"CVE-2025-59479"},"products":["Mattermost"],"published":"2025-11-13","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":"2025-11-13","vendors":["Mattermost"]},"summary":"Attackers can steal user session credentials by exploiting inadequate validation of SSO redirect tokens in the Mattermost mobile application.","url":"https://insights.sbomify.com/CVE-2025-59480/"}
