CVE-2026-82797 · Severity: medium · CVSS 5.5 · Published 2026-08-31

Samsung's rlottie is an open-source animation rendering library used by applications to display vector animations. A serialized animation file with deeply nested shape groups can trigger unbounded recursion during parsing, exhausting memory and crashing the application. This could be exploited by delivering a malicious animation file to cause denial of service.

Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## Technical details

The vulnerability is an uncontrolled recursion flaw in the shape group parsing logic of rlottie. The parseGroupObject function recursively processes nested "gr" (group) objects without enforcing a depth limit, allowing an attacker to craft a serialized animation payload with arbitrarily deep nesting. An application processing such a file will exhaust the call stack and crash. The fix applies a maximum nesting depth limit of 32 to the recursive parsing, halting traversal of deeper content. Network or local delivery of a malicious animation file is required; no authentication is needed.
