Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-59763 exists.\n\nAffected packages and fixed versions:\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.27.0\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.27.0\n- gitea.dev (Go): affected all versions; fixed in 1.27.0\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-2026-59763/ (Markdown: https://insights.sbomify.com/CVE-2026-59763/index.md)","id":"CVE-2026-59763","markdown":"https://insights.sbomify.com/CVE-2026-59763/index.md","name":"CVE-2026-59763","record":{"aliases":["GHSA-9mq6-mqjj-c2c5","GO-2026-6049","MINI-jcxj-wcxw-f3v3","MINI-xg9g-jpq5-94hg"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Gitea Git Server","requires_auth":"low_privilege","summary":"Attackers can cause resource amplification and denial of service by uploading Arch packages with unbounded metadata to Gitea.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gitea","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Unbounded Arch package file metadata can cause resource amplification in Gitea package uploads","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":"Unbounded Arch package file metadata can cause resource amplification in Gitea package uploads","id":"CVE-2026-59763","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":3,"n_references":3,"next":{"headline":"Command injection in WRC-X3000GS3-B","id":"CVE-2026-59764"},"packages":[{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":null,"source":"GHSA-9mq6-mqjj-c2c5"},{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GHSA-9mq6-mqjj-c2c5"},{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"gitea.dev","purl":"pkg:golang/gitea.dev","source":"GO-2026-6049"}],"prev":{"headline":"BIG-IP HTTP/2 vulnerability","id":"CVE-2026-59762"},"products":["Gitea Open Source Git Server"],"published":"2026-08-13","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":"2026-08-13","vendors":["Gitea"]},"summary":"Attackers can cause resource amplification and denial of service by uploading Arch packages with unbounded metadata to Gitea.","url":"https://insights.sbomify.com/CVE-2026-59763/"}
