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-2024-22403 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-2024-22403/ (Markdown: https://insights.sbomify.com/CVE-2024-22403/index.md)","id":"CVE-2024-22403","markdown":"https://insights.sbomify.com/CVE-2024-22403/index.md","name":"CVE-2024-22403","record":{"aliases":["GHSA-wppc-f5g8-vx36"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Nextcloud server","requires_auth":"low_privilege","summary":"Attackers can hijack user accounts by reusing intercepted OAuth2 authorization codes that never expire in Nextcloud server.","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":3,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-613","name":"DEPRECATED: Insufficient Session Expiration"}],"description":"Nextcloud server is a self hosted personal cloud system. In affected versions OAuth codes did not expire. When an attacker would get access to an authorization code they could authenticate at any time using the code. As of version 28.0.0 OAuth codes are invalidated after 10 minutes and will no longer be authenticated. To exploit this vulnerability an attacker would need to intercept an OAuth code from a user session. It is recommended that the Nextcloud Server is upgraded to 28.0.0. There are no known workarounds for this vulnerability.","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":"OAuth2 authorization codes are valid indefinetly in Nextcloud server","id":"CVE-2024-22403","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"nextcloud:nextcloud_server","products":["nextcloud:nextcloud_server"],"type":"auth_bypass","year":"2024"},"n_packages":0,"n_references":4,"next":{"headline":"Permissions bypass in Nextcloud with the files zip app","id":"CVE-2024-22404"},"packages":[],"prev":{"headline":"Improper handling of request URLs in Nextcloud Guests app allows guest users to bypass app allowlist","id":"CVE-2024-22402"},"products":["security-advisories"],"published":"2024-01-18","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":"partial"},"state":"PUBLISHED","updated":"2025-06-17","vendors":["nextcloud"]},"summary":"Attackers can hijack user accounts by reusing intercepted OAuth2 authorization codes that never expire in Nextcloud server.","url":"https://insights.sbomify.com/CVE-2024-22403/"}
