Description
restbed through 5.0.0 buffers HTTP request headers without enforcing a maximum size limit, allowing remote unauthenticated attackers to exhaust server memory. Attackers can open TCP connections and stream bytes indefinitely without sending the header delimiter, forcing the server to allocate unbounded heap memory until the process is killed.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2026-103471 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
