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-2026-42931 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-2026-42931/ (Markdown: https://insights.sbomify.com/CVE-2026-42931/index.md)","id":"CVE-2026-42931","markdown":"https://insights.sbomify.com/CVE-2026-42931/index.md","name":"CVE-2026-42931","record":{"aliases":["GHSA-wwqq-x6w4-frm2","GO-2026-6082","MINI-84j6-jh45-c486","MINI-j36m-vgvj-3c72"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Git server","requires_auth":"low_privilege","summary":"Attackers can cause denial of service in Gitea by exploiting unbounded memory allocation in the NPM package tag endpoint.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gitea","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"Denial of Service via Unbounded io.ReadAll in NPM Package Tag Endpoint","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":"Denial of Service via Unbounded io.ReadAll in NPM Package Tag Endpoint","id":"CVE-2026-42931","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":"Naxclow IoT Platform Generation of Predictable Numbers or Identifiers","id":"CVE-2026-42932"},"packages":[{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":null,"source":"GHSA-wwqq-x6w4-frm2"},{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GHSA-wwqq-x6w4-frm2"},{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"gitea.dev","purl":"pkg:golang/gitea.dev","source":"GO-2026-6082"}],"prev":{"headline":"Appliance mode iControl REST vulnerability","id":"CVE-2026-42930"},"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 denial of service in Gitea by exploiting unbounded memory allocation in the NPM package tag endpoint.","url":"https://insights.sbomify.com/CVE-2026-42931/"}
