CVE-2026-45047 (GCVE-0-2026-45047)
Vulnerability from nvd – Published: 2026-05-27 16:37 – Updated: 2026-05-27 18:03
VLAI
Title
bird-lg-go: Fatal Out-of-Memory (OOM) Denial of Service via Unbounded JSON Decoding
Summary
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(&request) 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. This vulnerability is fixed in 1.4.5.

CVE-2026-26514 (GCVE-0-2026-26514)
Vulnerability from nvd – Published: 2026-03-04 00:00 – Updated: 2026-03-04 15:39

Summary
An Argument Injection vulnerability exists in bird-lg-go before commit 6187a4e. The traceroute module uses shlex.Split to parse user input without validation, allowing remote attackers to inject arbitrary flags (e.g., -w, -q) via the q parameter. This can be exploited to cause a Denial of Service (DoS) by exhausting system resources.
