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-2025-47790 in the wild and no public exploit code.\n\nAffected product: Nextcloud Nextcloud Server. 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-2025-47790/ (Markdown: https://insights.sbomify.com/CVE-2025-47790/index.md)","id":"CVE-2025-47790","markdown":"https://insights.sbomify.com/CVE-2025-47790/index.md","name":"CVE-2025-47790","record":{"aliases":["GHSA-9h3w-f3h4-qqrh"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Nextcloud Server","requires_auth":"low_privilege","summary":"Attackers can bypass second-factor authentication after session timeout if remember_login_cookie_lifetime is set to zero.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"nextcloud_server","vendor":"nextcloud"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Nextcloud Server is a self hosted personal cloud system.

The bug caused skipping the second factor confirmation after a successful login with the username and password when the server was configured with `remember_login_cookie_lifetime` set to `0`, once the session expired on the page to select the second factor and the page is reloaded. Nextcloud Server 29.0.15, 30.0.9, and 31.0.3 and Nextcloud Enterprise Server is upgraded to 26.0.13.15, 27.1.11.15, 28.0.14.6, 29.0.15, 30.0.9 and 31.0.3 contain a patch. As a workaround, set the `remember_login_cookie_lifetime` in config.php to a value other than `0`, e.g. `900`. Beware that this is only a workaround for new sessions created after the configuration change. System administration can delete affected sessions.","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":"Nextcloud Server doesn't request second factor after session timeout","id":"CVE-2025-47790","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"nextcloud:nextcloud_server","products":["nextcloud:nextcloud_server"],"type":"auth_bypass","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"Nextcloud Server's test remote endpoint is not rate limited","id":"CVE-2025-47791"},"packages":[],"prev":{"headline":"Horilla Open Redirect Vulnerability in Login","id":"CVE-2025-47789"},"products":["security-advisories"],"published":"2025-05-16","related":[{"cvss_score":9.3,"headline":"Preview generation used third-party library not suited for user-generated content in Nextcloud server","id":"CVE-2021-32802","kev_date_added":null,"published":"2021-09-07"},{"cvss_score":9.1,"headline":"Scope of workflow operations is not validated in nextcloud server","id":"CVE-2023-26482","kev_date_added":null,"published":"2023-03-30"},{"cvss_score":8.8,"headline":"Auth bypass in Nextcloud Server","id":"CVE-2018-3775","kev_date_added":null,"published":"2018-08-12"},{"cvss_score":8.7,"headline":"Nextcloud Server password reset endpoint is not brute force protected","id":"CVE-2023-35172","kev_date_added":null,"published":"2023-06-23"},{"cvss_score":8.7,"headline":"Nextcloud Server's brute force protection allows someone to send more requests than intended","id":"CVE-2023-32320","kev_date_added":null,"published":"2023-06-22"},{"cvss_score":8.6,"headline":"Trusted servers exchange can be triggered by attacker","id":"CVE-2021-32656","kev_date_added":null,"published":"2021-06-01"},{"cvss_score":8.5,"headline":"Nextcloud Server users can make external storage mount points inaccessible for other users","id":"CVE-2023-48239","kev_date_added":null,"published":"2023-11-21"}],"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":"total"},"state":"PUBLISHED","updated":"2025-05-16","vendors":["nextcloud"]},"summary":"Attackers can bypass second-factor authentication after session timeout if remember_login_cookie_lifetime is set to zero.","url":"https://insights.sbomify.com/CVE-2025-47790/"}
