Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-28737 exists.\n\nAffected packages and fixed versions:\n- code.gitea.io/gitea (Go): affected from 1.25.0; fixed in 1.26.0\n- code.gitea.io/gitea (Go): affected from 1.25.0; fixed in 1.26.0\n- code.gitea.io/gitea (Go): affected from 1.25.0; fixed in 1.26.0\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-2026-28737/ (Markdown: https://insights.sbomify.com/CVE-2026-28737/index.md)","id":"CVE-2026-28737","markdown":"https://insights.sbomify.com/CVE-2026-28737/index.md","name":"CVE-2026-28737","record":{"aliases":["GHSA-9cpj-qc93-vw8v","GO-2026-5286"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Gitea Git Server","requires_auth":"low_privilege","summary":"Attackers can inject malicious scripts via glTF files in Gitea's 3D viewer, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gitea","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Gitea versions from 1.25.0 before 1.26.0 allow stored cross-site scripting through the extensionsRequired field in glTF files rendered by the 3D file viewer.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Gitea 3D file viewer allows stored XSS through glTF extensionsRequired","id":"CVE-2026-28737","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":3,"n_references":4,"next":{"headline":"Gitea LFS object reuse bypasses Code-unit authorization","id":"CVE-2026-28740"},"packages":[{"ecosystem":"Go","fixed":["1.26.0"],"introduced":["1.25.0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":null,"source":"GHSA-9cpj-qc93-vw8v"},{"ecosystem":"Go","fixed":["1.26.0"],"introduced":["1.25.0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GHSA-9cpj-qc93-vw8v"},{"ecosystem":"Go","fixed":["1.26.0"],"introduced":["1.25.0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GO-2026-5286"}],"prev":{"headline":"Focalboard IDOR in file content endpoint allows cross-user file access (unsupported product, no fix)","id":"CVE-2026-28736"},"products":["Gitea Open Source Git Server"],"published":"2026-07-03","related":[],"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":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-07","vendors":["Gitea"]},"summary":"Attackers can inject malicious scripts via glTF files in Gitea's 3D viewer, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2026-28737/"}
