Summary
Routinator, an open-source RPKI validator used by network operators to check Internet routing data, is affected. Because it caches a newly retrieved trust anchor certificate without validating it first, a failed or malicious update can overwrite a known good certificate, which could weaken the integrity of route origin validation.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
