CVE-2026-26738 describes a high-severity buffer overflow vulnerability (CWE-121) in Uderzo Software SpaceSniffer v.2.0.5.18. This flaw allows an attacker to achieve arbitrary code execution on a target system when a user opens a specially crafted .sns snapshot file. Rated with a CVSS v3.1 score of 7.8 (High), the vulnerability requires local access and user interaction (UI:R) but has low attack complexity (AC:L), leading to high impacts on confidentiality, integrity, and availability. While listed on an "Active" hot list, there is currently no evidence of active exploitation in the wild (KEV: No), nor are public exploit modules available. Its extremely low EPSS score of 0.00069, coupled with a lack of community discussion or media coverage, indicates a very low probability of widespread exploitation at present.
