CVE-2026-47306 · Severity: medium · CVSS 6.1 · Published 2026-06-04

Samsung rlottie is an open-source library used to render vector animations (Lottie files) on various platforms, including mobile devices and smart appliances. A vulnerability in how it processes animation files allows a specially crafted file to crash the application. This could lead to a denial-of-service, causing apps or device interfaces that display these animations to stop working or restart unexpectedly.

## Technical details

An uncontrolled recursion vulnerability (CWE-674) exists in Samsung's rlottie library due to improper handling of circular asset references within Lottie JSON files. Specifically, a malicious file containing self-referencing or mutually referencing 'precomp' assets triggers infinite recursion in renderer::CompLayer::CompLayer() via createLayerItem(). This exhaustion of stack space results in a SIGSEGV crash. The attack requires a user to open or load a specially crafted animation file. The issue was addressed by implementing a directed asset dependency graph and using Breadth-First Search (BFS) to detect and skip cyclic dependencies during the layer resolution phase.
