The vulnerability identified as CVE-2026-47309 in Samsung Open Source Escargot involves uncontrolled recursion when processing serialized data payloads. This can lead to denial of service conditions by exhausting system resources. The affected version is specified by a particular commit hash. The CVSS 3.1 vector indicates the attack requires local access with low complexity, no privileges, and user interaction, impacting availability only. No official fix or mitigation has been published by Samsung Open Source, and no evidence of exploitation exists currently.

The primary impact of this vulnerability is denial of service (availability impact) caused by uncontrolled recursion triggered by oversized serialized data payloads. There is no confidentiality or integrity impact reported. Exploitation requires local access and user interaction, limiting the attack surface. No known exploits have been observed in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, avoid processing untrusted serialized data payloads locally in the affected Escargot version. Monitor vendor channels for updates regarding patches or mitigations.
