An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2019-15619 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-2019-15619/ (Markdown: https://insights.sbomify.com/CVE-2019-15619/index.md)","id":"CVE-2019-15619","markdown":"https://insights.sbomify.com/CVE-2019-15619/index.md","name":"CVE-2019-15619","record":{"aliases":["GHSA-mvc5-w9jr-jvqm"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Nextcloud Server","requires_auth":"high_privilege","summary":"Cross-site scripting vulnerability in Nextcloud allows attackers to execute scripts via malicious file, conversation, or board names.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"deck","vendor":"nextcloud"},{"product":"nextcloud_server","vendor":"nextcloud"},{"product":"talk","vendor":"nextcloud"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Improper neutralization of file names, conversation names and board names in Nextcloud Server 16.0.3, Nextcloud Talk 6.0.3 and Nextcloud Deck 0.6.5 causes an XSS when linking them with each others in a project.","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":"Cross-site scripting in Nextcloud Server","id":"CVE-2019-15619","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"nextcloud:nextcloud_server","products":["nextcloud:nextcloud_server"],"type":"xss","year":"2019"},"n_packages":0,"n_references":4,"next":{"headline":"Information disclosure in Nextcloud Talk","id":"CVE-2019-15620"},"packages":[],"prev":{"headline":"Cross-site scripting in Nextcloud Server","id":"CVE-2019-15618"},"products":["Nextcloud Server"],"published":"2020-02-04","related":[{"cvss_score":8.1,"headline":"Missing permission check on Deck API","id":"CVE-2021-39225","kev_date_added":null,"published":"2021-10-25"},{"cvss_score":8,"headline":"Missing authorization in Nextcloud Deck","id":"CVE-2020-8182","kev_date_added":null,"published":"2020-10-05"},{"cvss_score":6.5,"headline":"Circle can be accessed by non-Circle members in Nextcloud Deck","id":"CVE-2021-37631","kev_date_added":null,"published":"2021-09-07"},{"cvss_score":6.5,"headline":"Information disclosure in Nextcloud Deck","id":"CVE-2021-22913","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":5.8,"headline":"Nextcloud Deck card vulnerable to data leak to unauthorized users via reference preview cache","id":"CVE-2023-22469","kev_date_added":null,"published":"2023-01-10"},{"cvss_score":5.4,"headline":"Nextcloud Deck app allowed user with \"Can share\" permission to modify permissions of other non-owners","id":"CVE-2025-66557","kev_date_added":null,"published":"2025-12-05"},{"cvss_score":5,"headline":"Possibility for anyone to add a stack with existing tasks on anyone's board in Nextcloud Deck","id":"CVE-2022-29159","kev_date_added":null,"published":"2022-05-20"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Cross-site scripting vulnerability in Nextcloud allows attackers to execute scripts via malicious file, conversation, or board names.","url":"https://insights.sbomify.com/CVE-2019-15619/"}
