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-2026-45047 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/xddxdd/bird-lg-go (Go): affected all versions; fixed in 0.0.0-20260507060110-0ff87024cb9e\n- github.com/xddxdd/bird-lg-go (Go): affected all versions; fixed in 0.0.0-20260507060110-0ff87024cb9e\n- github.com/xddxdd/bird-lg-go (Go): affected all versions; fixed in 0.0.0-20260507060110-0ff87024cb9e\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-2026-45047/ (Markdown: https://insights.sbomify.com/CVE-2026-45047/index.md)","id":"CVE-2026-45047","markdown":"https://insights.sbomify.com/CVE-2026-45047/index.md","name":"CVE-2026-45047","record":{"aliases":["GHSA-39qr-rc93-vhqm","GO-2026-5077"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"BIRD looking glass","requires_auth":"none","summary":"An unauthenticated remote attacker can cause a fatal out-of-memory denial of service by sending an unbounded JSON payload to the API handler.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","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-400","name":"Uncontrolled Resource Consumption"}],"description":"bird-lg-go is a BIRD looking glass in Go. Prior to 1.4.5, the apiHandler (and similarly webHandlerTelegramBot) processes user-provided JSON payloads by directly using json.NewDecoder(r.Body).Decode(\u0026request) without restricting the maximum read size. An unauthenticated remote attacker can stream an extremely large, endless JSON payload (e.g., several Gigabytes of padding) over a single TCP connection. Because Go's JSON decoder attempts to allocate memory for the entire parsed structure, this rapidly exhausts the host's physical RAM or container limits, leading to an unrecoverable fatal error: runtime: out of memory.
