0 CVE-2026-33349 is a medium severity vulnerability in the fast-xml-parser library versions from 4.0.0-beta.3 up to before 5.5.7. The issue arises because the DocTypeReader component uses JavaScript truthy checks on maxEntityCount and maxEntitySize configuration parameters. When these limits are explicitly set to zero, intending to disallow XML entities or restrict their size, the falsy evaluation causes the limits to be bypassed. This allows an attacker supplying crafted XML input to trigger unbounded entity expansion, resulting in memory exhaustion and denial of service (DoS). No authentication or user interaction is required, and the vulnerability can be exploited remotely over the network.
