Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-77165 exists.\n\nAffected packages and fixed versions:\n- nextcloud (Bitnami): affected from 32.0.0; fixed in 34.0.1\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-2026-77165/ (Markdown: https://insights.sbomify.com/CVE-2026-77165/index.md)","id":"CVE-2026-77165","markdown":"https://insights.sbomify.com/CVE-2026-77165/index.md","name":"CVE-2026-77165","record":{"aliases":["BIT-nextcloud-2026-77165","GHSA-77h3-rj6p-8wj8","MINI-gg48-wpf6-3mpp"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Nextcloud Server","requires_auth":"low_privilege","summary":"File owners cannot unlock files locked by other users, causing permanent file locks and denial of service in Nextcloud Server.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"File owners were unable to unlock TYPE_TOKEN locks placed by other users, leaving files permanently locked with no recovery path outside of the database.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Business logic in Server","id":"CVE-2026-77165","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"business_logic","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"Business logic in Collectives","id":"CVE-2026-77166"},"packages":[{"ecosystem":"Bitnami","fixed":["34.0.1"],"introduced":["32.0.0"],"last_affected":[],"package":"nextcloud","purl":"pkg:bitnami/nextcloud","source":"BIT-nextcloud-2026-77165"}],"prev":{"headline":"Server-side request forgery in Server","id":"CVE-2026-77164"},"products":["Server"],"published":"2026-09-21","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-21","vendors":["Nextcloud"]},"summary":"File owners cannot unlock files locked by other users, causing permanent file locks and denial of service in Nextcloud Server.","url":"https://insights.sbomify.com/CVE-2026-77165/"}
