Parameter Value
CVSS 8.7 (HIGH)
Affected Versions before 4.81.0
Fixed In 4.81.0
Type CWE-770 (Allocation Without Limits)

Public PoC No

Fleet is open source device management software. Prior to 4.81.0, Fleet contained multiple unauthenticated HTTP endpoints that read request bodies without enforcing a size limit. An unauthenticated attacker could exploit this behavior by sending large or repeated HTTP payloads, causing excessive memory allocation and resulting in a denial-of-service (DoS) condition.

Version 4.81.0 patches the issue.
