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-2021-28378 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.13.4\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.13.4\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.13.4\n- gitea (Bitnami): affected from 1.12.0; fixed in 1.12.7, 1.13.4\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-2021-28378/ (Markdown: https://insights.sbomify.com/CVE-2021-28378/index.md)","id":"CVE-2021-28378","markdown":"https://insights.sbomify.com/CVE-2021-28378/index.md","name":"CVE-2021-28378","record":{"aliases":["BIT-gitea-2021-28378","CLEANSTART-2025-BP00020","GHSA-g95p-88p4-76cm","GO-2022-0832"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Gitea Git service","requires_auth":"low_privilege","summary":"An attacker can inject malicious scripts via issue data in Gitea, potentially leading to session hijacking or code execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"gitea","vendor":"gitea"}],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AC:H/AV:N/A:N/C:L/I:L/PR:L/S:U/UI:R","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Gitea 1.12.x and 1.13.x before 1.13.4 allows XSS via certain issue data in some situations.","ecosystems":["Bitnami","Go"],"exploits":{"exploitdb":0,"first_seen":"2021-08-01","github_poc":1,"max_poc_stars":4,"metasploit":0,"nuclei":0,"refs":[{"date":"2021-08-01T13:16:53Z","kind":"github_poc","ref":"https://github.com/pandatix/CVE-2021-28378","stars":4,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"Cross-site Scripting in Gitea","id":"CVE-2021-28378","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"gitea:gitea","products":["gitea:gitea"],"type":"xss","year":"2021"},"n_packages":4,"n_references":3,"next":{"headline":"File upload in n/a","id":"CVE-2021-28379"},"packages":[{"ecosystem":"Bitnami","fixed":["1.12.7","1.13.4"],"introduced":["1.12.0","1.13.0"],"last_affected":[],"package":"gitea","purl":"pkg:bitnami/gitea","source":"BIT-gitea-2021-28378"},{"ecosystem":"Go","fixed":["1.13.4"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":null,"source":"GHSA-g95p-88p4-76cm"},{"ecosystem":"Go","fixed":["1.13.4"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GHSA-g95p-88p4-76cm"},{"ecosystem":"Go","fixed":["1.13.4"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GO-2022-0832"}],"prev":{"headline":"Path traversal in n/a","id":"CVE-2021-28377"},"products":["n/a"],"published":"2021-03-15","related":[{"cvss_score":9.8,"headline":"Gitea Code Injection","id":"CVE-2026-60004","kev_date_added":"2026-08-25","published":"2026-08-26"},{"cvss_score":9.8,"headline":"Gitea WebAuthn bypass during OAuth and OIDC sign-in","id":"CVE-2026-73278","kev_date_added":null,"published":"2026-10-06"},{"cvss_score":9.8,"headline":"Gitea fork workflow approval bypass through maintainer-triggered events","id":"CVE-2026-94205","kev_date_added":null,"published":"2026-10-06"},{"cvss_score":9.8,"headline":"Gitea vulnerable to Argument Injection","id":"CVE-2022-42968","kev_date_added":null,"published":"2022-10-16"},{"cvss_score":9.8,"headline":"Improper Privilege Management in Gitea","id":"CVE-2021-45330","kev_date_added":null,"published":"2022-02-09"},{"cvss_score":9.8,"headline":"Reuse of one time passwords allowed in Gitea","id":"CVE-2021-45331","kev_date_added":null,"published":"2022-02-09"},{"cvss_score":9.8,"headline":"Capture-replay in Gitea","id":"CVE-2021-45327","kev_date_added":null,"published":"2022-02-08"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"An attacker can inject malicious scripts via issue data in Gitea, potentially leading to session hijacking or code execution.","url":"https://insights.sbomify.com/CVE-2021-28378/"}
