plist npm package denial of service via crafted binary plist

high severity · published 2026-11-06

An unauthenticated attacker can send a tiny crafted binary plist (under 200 bytes) with chained self-referencing object indices, triggering exponential recursive work and memory growth in the binary plist parser. The Node.js process crashes unrecoverably with an out-of-memory error, denying service to anything that parses untrusted binary plists.
