Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2026-42504
CWEhttps://cwe.mitre.org/data/definitions/407.html

Decoding a maliciously-crafted MIME header containing many invalid encoded-words can consume excessive CPU.

Weakness

An algorithm in a product has an inefficient worst-case computational complexity that may be detrimental to system performance and can be triggered by an attacker, typically using crafted manipulations that ensure that the worst case is being reached.
