An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-25828 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-2021-25828/ (Markdown: https://insights.sbomify.com/CVE-2021-25828/index.md)","id":"CVE-2021-25828","markdown":"https://insights.sbomify.com/CVE-2021-25828/index.md","name":"CVE-2021-25828","record":{"aliases":["GHSA-9pjf-87x2-r68m"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Emby Media Server","requires_auth":"none","summary":"Attackers can execute arbitrary scripts in user browsers via crafted GET requests to the web interface, potentially leading to session hijacking or data theft.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"emby","vendor":"emby"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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":"Emby Server versions \u003c 4.6.0.50 is vulnerable to Cross Site Scripting (XSS) vulnerability via a crafted GET request to /web.","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-2021-25828","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2021-25829"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2021-25827"},"products":["n/a"],"published":"2023-06-28","related":[{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2021-25827","kev_date_added":null,"published":"2023-06-28"},{"cvss_score":9.8,"headline":"Server-side request forgery in n/a","id":"CVE-2020-26948","kev_date_added":null,"published":"2020-10-10"},{"cvss_score":9.3,"headline":"Emby Server allows attackers to gain administrative server access without preconditions","id":"CVE-2025-64113","kev_date_added":null,"published":"2025-12-09"},{"cvss_score":8.4,"headline":"Emby Server is Vulnerable to Remote Code Execution Through XSS in Admin Dashboard","id":"CVE-2025-64325","kev_date_added":null,"published":"2025-11-18"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2022-36223","kev_date_added":null,"published":"2022-12-16"}],"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":"2024-12-05","vendors":["n/a"]},"summary":"Attackers can execute arbitrary scripts in user browsers via crafted GET requests to the web interface, potentially leading to session hijacking or data theft.","url":"https://insights.sbomify.com/CVE-2021-25828/"}
