An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-104636 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-2026-104636/ (Markdown: https://insights.sbomify.com/CVE-2026-104636/index.md)","id":"CVE-2026-104636","markdown":"https://insights.sbomify.com/CVE-2026-104636/index.md","name":"CVE-2026-104636","record":{"aliases":["BIT-gitea-2026-104636","GHSA-g4hw-fg4c-89mq","MINI-646q-v3r7-r24w","MINI-g3cr-g4f9-67qf"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Gitea Git service","requires_auth":"none","summary":"A repository administrator can trigger Server-Side Request Forgery in Gitea by exploiting unvalidated HTTP redirects during Git operations, potentially accessing internal services.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gitea","cpe":[{"product":"gitea","vendor":"gitea"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Gitea validated the initial remote URL for push mirrors, wiki remote checks, and fetches of migrated pull request heads, but the subsequent raw Git operations followed HTTP redirects without revalidating the destination.
