CVE-2026-77620 Vector: Unauthenticated denial of service in the `logstash` source via nested compressed frames (stack exhaustion and decompression amplification).

Vector is a high-performance observability data pipeline. From 0.15.0 until 0.57.0, the logstash source feeds each decompressed frame back into its decoder without limiting nested compression depth. An unauthenticated remote peer that can reach the default 0.0.0.0:5044 listener can send many nest...

CVE-2026-77619 Vector: Unauthenticated denial of service in the `logstash` source via unbounded memory allocation.

Vector is a high-performance observability data pipeline. From 0.15.0 until 0.57.0, the logstash source reads a 32-bit compressed-frame length from the network and uses it to size an in-memory buffer without an upper bound. An unauthenticated remote peer that can reach the default 0.0.0.0:5044...
