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-2021-39391 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/beego/beego/v2 (Go): affected all versions; fixed in 2.0.2\n- github.com/beego/beego/v2 (Go): affected all versions; fixed in 2.0.2\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-2021-39391/ (Markdown: https://insights.sbomify.com/CVE-2021-39391/index.md)","id":"CVE-2021-39391","markdown":"https://insights.sbomify.com/CVE-2021-39391/index.md","name":"CVE-2021-39391","record":{"aliases":["GHSA-c77f-4rgj-jfr4"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Beego web framework","requires_auth":"none","summary":"Attackers can inject malicious scripts via URI paths in the Beego admin panel, potentially compromising administrator sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"beego","vendor":"beego"}],"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":"Cross Site Scripting (XSS) vulnerability exists in the admin panel in Beego v2.0.1 via the URI path in an HTTP request, which is activated by administrators viewing the \"Request Statistics\" page.","ecosystems":["Go"],"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 in Beego","id":"CVE-2021-39391","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"xss","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Deserialization in n/a","id":"CVE-2021-39392"},"packages":[{"ecosystem":"Go","fixed":["2.0.2"],"introduced":["0"],"last_affected":[],"package":"github.com/beego/beego/v2","purl":null,"source":"GHSA-c77f-4rgj-jfr4"},{"ecosystem":"Go","fixed":["2.0.2"],"introduced":["0"],"last_affected":[],"package":"github.com/beego/beego/v2","purl":"pkg:golang/github.com/beego/beego/v2","source":"GHSA-c77f-4rgj-jfr4"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-39390"},"products":["n/a"],"published":"2021-09-14","related":[{"cvss_score":9.8,"headline":"Path Traversal in Beego","id":"CVE-2022-31836","kev_date_added":null,"published":"2022-07-05"},{"cvss_score":9.8,"headline":"Access control bypass in beego","id":"CVE-2022-31259","kev_date_added":null,"published":"2022-05-21"},{"cvss_score":9.8,"headline":"Access control bypass in Beego","id":"CVE-2021-30080","kev_date_added":null,"published":"2022-04-05"},{"cvss_score":9.3,"headline":"Beego allows Reflected/Stored XSS in Beego's RenderForm() Function Due to Unescaped User Input","id":"CVE-2025-30223","kev_date_added":null,"published":"2025-03-31"},{"cvss_score":8.8,"headline":"Beego privilege escalation vulnerability","id":"CVE-2024-40464","kev_date_added":null,"published":"2024-07-31"},{"cvss_score":8.8,"headline":"Beego privilege escalation vulnerability","id":"CVE-2024-40465","kev_date_added":null,"published":"2024-07-31"},{"cvss_score":7.8,"headline":"Privilege escalation in beego","id":"CVE-2021-27116","kev_date_added":null,"published":"2022-04-05"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can inject malicious scripts via URI paths in the Beego admin panel, potentially compromising administrator sessions.","url":"https://insights.sbomify.com/CVE-2021-39391/"}
