OpenClaw < 2026.2.14 - Denial of Service via Unguarded Archive Extraction in extractArchive
OpenClaw versions prior to 2026.2.14 contain a denial of service vulnerability in the extractArchive function within src/infra/archive.ts that allows attackers to consume excessive CPU, memory, and disk resources through high-expansion ZIP and TAR archives. Remote attackers can trigger resource exhaustion by providing maliciously crafted archive files during install or update operations, causing service degradation or system unavailability.
