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-2021-3780 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- peertube (npm): affected all versions; fixed in 3.4.0\n- peertube (npm): affected all versions; fixed in 3.4.0\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-2021-3780/ (Markdown: https://insights.sbomify.com/CVE-2021-3780/index.md)","id":"CVE-2021-3780","markdown":"https://insights.sbomify.com/CVE-2021-3780/index.md","name":"CVE-2021-3780","record":{"aliases":["GHSA-f2c5-997w-7f5c"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"PeerTube video platform","requires_auth":"none","summary":"Attackers can inject malicious scripts into PeerTube pages, potentially stealing user sessions or executing code in victim browsers.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"peertube","vendor":"framasoft"}],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"peertube is vulnerable to Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Cross-site Scripting (XSS) - Stored in chocobozzz/peertube","id":"CVE-2021-3780","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Command injection in ghostscript","id":"CVE-2021-3781"},"packages":[{"ecosystem":"npm","fixed":["3.4.0"],"introduced":["0"],"last_affected":[],"package":"peertube","purl":null,"source":"GHSA-f2c5-997w-7f5c"},{"ecosystem":"npm","fixed":["3.4.0"],"introduced":["0"],"last_affected":[],"package":"peertube","purl":"pkg:npm/peertube","source":"GHSA-f2c5-997w-7f5c"}],"prev":{"headline":"Ruby-MySQL Gem Client File Read","id":"CVE-2021-3779"},"products":["chocobozzz/peertube"],"published":"2021-09-15","related":[{"cvss_score":7.6,"headline":"Insecure Storage of Sensitive Information in chocobozzz/peertube","id":"CVE-2022-0881","kev_date_added":null,"published":"2022-03-09"},{"cvss_score":7.5,"headline":"PeerTube ActivityPub Crawl Infinite Loop DoS","id":"CVE-2025-32947","kev_date_added":null,"published":"2025-04-15"},{"cvss_score":7.5,"headline":"PeerTube ActivityPub Playlist Creation Blind SSRF and DoS","id":"CVE-2025-32948","kev_date_added":null,"published":"2025-04-15"},{"cvss_score":6.5,"headline":"PeerTube User Import Authenticated Persistent Denial of Service","id":"CVE-2025-32944","kev_date_added":null,"published":"2025-04-15"},{"cvss_score":6.5,"headline":"PeerTube User Import Authenticated Resource Exhaustion","id":"CVE-2025-32949","kev_date_added":null,"published":"2025-04-15"},{"cvss_score":6.5,"headline":"Server-Side Request Forgery (SSRF) in chocobozzz/peertube","id":"CVE-2022-0508","kev_date_added":null,"published":"2022-02-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2024-08-03","vendors":["chocobozzz"]},"summary":"Attackers can inject malicious scripts into PeerTube pages, potentially stealing user sessions or executing code in victim browsers.","url":"https://insights.sbomify.com/CVE-2021-3780/"}
