Improper input validation vulnerability in Samsung Open Source rlottie allows Oversized Serialized Data Payloads.
AnalysisAI
Resource exhaustion via oversized serialized Lottie animation payloads in Samsung Open Source rlottie allows denial-of-service against any application embedding the library. The library failed to bound precomposition nesting depth, total render-node count, Repeater element copy counts, and did not validate non-finite float values (NaN/Infinity) for polystar and polygon point counts during deserialization and rendering. …

Vulnerability AssessmentAI
| Exploitation | The vulnerability requires that a user or application process a crafted Lottie animation file (.json format) using a vulnerable version of rlottie. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 5.5 (AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H) correctly reflects a local, user-triggered, availability-only impact - this is a crash/hang in the rendering process, not remote code execution. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker creates a Lottie JSON animation file containing precomposition layers nested 33 or more levels deep, or a Repeater element with a copy count of several million, or polystar shapes with NaN point values. The file is delivered to a victim via email attachment, a web download, or as part of a crafted application resource bundle. … |
| Remediation | The upstream fix is available via GitHub PR #596 (https://github.com/Samsung/rlottie/pull/596), which introduces depth limits, node-budget caps, Repeater copy count capping, and non-finite float guards. … Detailed patch versions, workarounds, and compensating controls in full report. |
