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-2018-9999 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2018-9999/ (Markdown: https://insights.sbomify.com/CVE-2018-9999/index.md)","id":"CVE-2018-9999","markdown":"https://insights.sbomify.com/CVE-2018-9999/index.md","name":"CVE-2018-9999","record":{"aliases":["GHSA-cg35-j5q6-x5vf"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Zulip Server","requires_auth":"low_privilege","summary":"Cross-site scripting vulnerability in Zulip Server allows attackers to execute arbitrary scripts via user uploads, potentially leading to account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"zulip_server","vendor":"zulip"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"In Zulip Server versions before 1.7.2, there was an XSS issue with user uploads and the (default) LOCAL_UPLOADS_DIR storage backend.","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 n/a","id":"CVE-2018-9999","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-10000"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2018-9998"},"products":["n/a"],"published":"2018-04-18","related":[{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2019-18933","kev_date_added":null,"published":"2019-11-21"},{"cvss_score":8.8,"headline":"Code injection in n/a","id":"CVE-2020-15070","kev_date_added":null,"published":"2020-08-21"},{"cvss_score":8.8,"headline":"Missing authorization in Zulip Server","id":"CVE-2017-0910","kev_date_added":null,"published":"2017-11-27"},{"cvss_score":8.2,"headline":"Zulip Authentication Backend Configuration Bypass","id":"CVE-2025-31478","kev_date_added":null,"published":"2025-04-16"},{"cvss_score":8.2,"headline":"Cross-site scripting vulnerability in Zulip Server development branch via topic tooltip","id":"CVE-2023-33186","kev_date_added":null,"published":"2023-05-30"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2024-36612","kev_date_added":null,"published":"2024-11-29"},{"cvss_score":7.5,"headline":"Privilege escalation in n/a","id":"CVE-2020-14215","kev_date_added":null,"published":"2020-08-21"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Cross-site scripting vulnerability in Zulip Server allows attackers to execute arbitrary scripts via user uploads, potentially leading to account takeover.","url":"https://insights.sbomify.com/CVE-2018-9999/"}
