Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-101027 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gitea (Bitnami): affected all versions; fixed in 28.0.0\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-2026-101027/ (Markdown: https://insights.sbomify.com/CVE-2026-101027/index.md)","id":"CVE-2026-101027","markdown":"https://insights.sbomify.com/CVE-2026-101027/index.md","name":"CVE-2026-101027","record":{"aliases":["BIT-gitea-2026-101027","GHSA-fqjr-23c8-gg9m","MINI-cx62-rhf2-fx26","MINI-gr2v-v628-56qc"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Gitea Git hosting","requires_auth":"low_privilege","summary":"Attackers can bypass SSRF protections in Gitea migrations by controlling DNS for allowed domains, accessing internal services when ALLOWED_DOMAINS is configured.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gitea","cpe":[{"product":"gitea","vendor":"gitea"}],"cvss":{"score":7.7,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"}],"description":"When `[migrations] ALLOWED_DOMAINS` was configured, a hostname matching the allow list was accepted without checking its resolved address against the local-network restrictions.
