Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-77170 in the wild and no public exploit code.\n\nAffected product: Nextcloud Deck. 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-2026-77170/ (Markdown: https://insights.sbomify.com/CVE-2026-77170/index.md)","id":"CVE-2026-77170","markdown":"https://insights.sbomify.com/CVE-2026-77170/index.md","name":"CVE-2026-77170","record":{"aliases":["GHSA-c82v-5g56-99px"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Nextcloud Deck app","requires_auth":"low_privilege","summary":"Authenticated users can modify configuration settings for boards they do not own or manage due to missing authorization checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"The Deck config API allows authenticated users to set board-scoped configuration keys for arbitrary board IDs without validating whether the user owns or has permission to manage the referenced board.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Missing authorization in Deck","id":"CVE-2026-77170","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"A public shared collective always allowed recipients of the link to create pages.","id":"CVE-2026-77171"},"packages":[],"prev":{"headline":"Missing authorization in Team Folders","id":"CVE-2026-77169"},"products":["Deck"],"published":"2026-09-18","related":[],"sources":[{"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-18","vendors":["Nextcloud"]},"summary":"Authenticated users can modify configuration settings for boards they do not own or manage due to missing authorization checks.","url":"https://insights.sbomify.com/CVE-2026-77170/"}
