CVE-2026-47306

Uncontrolled Recursion Leading to Oversized Serialized Data Payloads in rlottie

Published Jun 4, 2026 CVSS 3.1 · 6.1 Medium EPSS < 1% KEV · Not listed

Description

Uncontrolled Recursion vulnerability in Samsung Open Source rlottie allows Oversized Serialized Data Payloads.

This issue affects rlottie: before e2d19e3b150e0e4a9586fa90b56fd3061cc98945.

Analysis

Technical impact

Uncontrolled recursion occurs when rlottie parses serialized data that can trigger an unbounded call stack. This flaw can exhaust memory or crash the process, resulting in a denial of service. The vulnerability reflects CWE-674: Uncontrolled Recursion, and it does not convey an information disclosure or arbitrary code execution vector as described.

Affected Systems

The flaw affects the Samsung Open Source rlottie library in all releases prior to commit e2d19e3b150e0e4a9586fa90b56fd3061cc98945. Any software that incorporates this version of rlottie is potentially vulnerable.

Risk and Exploitability

The CVSS score of 6.1 classifies the risk as medium. EPSS data is unavailable, and the vulnerability is not listed in CISA KEV, indicating no confirmed public exploitation yet. The likely attack vector is through supplying oversized or malicious serialized payloads to the library, which may be feasible if the host application accepts external data without proper size checks.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Update rlottie to a version after commit e2d19e3b150e0e4a9586fa90b56fd3061cc98945
Identify all applications that embed the vulnerable rlottie library and confirm the installed version; any application still using the older commit should be marked for immediate update to mitigate the denial‑of‑service risk
If an immediate update is not feasible, restrict the size of serialized data passed to rlottie by implementing a size limit or input validation in the host application to reduce the recursion attack surface
