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-2021-25878 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-2021-25878/ (Markdown: https://insights.sbomify.com/CVE-2021-25878/index.md)","id":"CVE-2021-25878","markdown":"https://insights.sbomify.com/CVE-2021-25878/index.md","name":"CVE-2021-25878","record":{"aliases":["GHSA-jvc3-8j2m-3v97"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Video streaming platform","requires_auth":"none","summary":"Remote attackers can steal administrator session cookies or perform administrative actions via reflected XSS in the videoName parameter.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"youphptube","vendor":"youphptube"}],"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":"AVideo/YouPHPTube 10.0 and prior is affected by multiple reflected Cross Script Scripting vulnerabilities via the videoName parameter which allows a remote attacker to steal administrators' session cookies or perform actions as an administrator.","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":"Cross-site scripting in n/a","id":"CVE-2021-25878","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-25893"},"packages":[],"prev":{"headline":"Code injection in n/a","id":"CVE-2021-25877"},"products":["n/a"],"published":"2021-11-01","related":[{"cvss_score":10,"headline":"SQL injection in YouPHPTube","id":"CVE-2019-5151","kev_date_added":null,"published":"2019-10-31"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2019-18662","kev_date_added":null,"published":"2019-11-02"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2019-16124","kev_date_added":null,"published":"2019-09-09"},{"cvss_score":8.9,"headline":"SQL injection in YouPHPTube","id":"CVE-2019-5150","kev_date_added":null,"published":"2019-10-31"},{"cvss_score":8.7,"headline":"YouPHPTube \u003c= 7.8 - Directory Traversal","id":"CVE-2021-47749","kev_date_added":null,"published":"2026-01-13"},{"cvss_score":7.5,"headline":"SQL injection in n/a","id":"CVE-2021-25874","kev_date_added":null,"published":"2021-11-01"},{"cvss_score":7.4,"headline":"SQL injection in YouPHPTube","id":"CVE-2019-5114","kev_date_added":null,"published":"2019-10-25"}],"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":"2026-07-09","vendors":["n/a"]},"summary":"Remote attackers can steal administrator session cookies or perform administrative actions via reflected XSS in the videoName parameter.","url":"https://insights.sbomify.com/CVE-2021-25878/"}
