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-2026-96399 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-2026-96399/ (Markdown: https://insights.sbomify.com/CVE-2026-96399/index.md)","id":"CVE-2026-96399","markdown":"https://insights.sbomify.com/CVE-2026-96399/index.md","name":"CVE-2026-96399","record":{"aliases":["BIT-gitea-2026-96399","GHSA-mw6q-qj47-9g5q","MINI-4363-x6mc-4vg8","MINI-v8x5-f5j5-qhxf"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Gitea self-hosted Git","requires_auth":"none","summary":"A user with repository edit rights can crash the Gitea instance by configuring a malicious external issue tracker regex, causing a denial of service for all users.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-248","name":"Uncaught Exception"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"A repository's external issue tracker regular expression containing alternating capture groups could produce invalid slice indexes when Gitea rendered issue references, causing a runtime panic that terminated the Gitea process.
