Impact	Successful exploitation can lead to arbitrary code execution, denial of service, or privilege escalation depending on the memory layout and protections in place.
Exploit ScenarioDerived	An attacker sends an oversized input to a vulnerable function, overwriting the return address on the stack to redirect execution to attacker-controlled shellcode.

AnalysisAIv1 – Mar 16, 2026

Electron is an open source framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. In versions prior to 28.3.2, 29.3.3, and 30.0.3, the nativeImage.createFromPath() and nativeImage.createFromBuffer() functions call a function downstream that is vulnerable to a heap buffer overflow. An Electron program that uses either of the affected functions is vulnerable to a buffer overflow if an attacker is in control of the image's height, width, and contents. This issue has been patched in versions 28.3.2, 29.3.3, and 30.0.3. There are no workarounds for this issue.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Heap Overflow HIGH

A heap overflow occurs when a program writes data beyond the bounds of a buffer allocated in the heap memory region.
