CVE-2026-50060 Overview
CVE-2026-50060 is a use-after-free vulnerability [CWE-416] affecting Siemens Solid Edge, a computer-aided design (CAD) application. The flaw resides in the DFT file parser and can be triggered when the application processes a specially crafted DFT file. Successful exploitation allows an attacker to execute arbitrary code in the context of the current process.
The vulnerability requires local access and user interaction, typically achieved by convincing a user to open a malicious DFT file. Siemens published advisory SSA-621657 documenting the issue and released fixed versions.
Critical Impact
An attacker can achieve arbitrary code execution in the context of the Solid Edge process by delivering a malicious DFT file to a user, compromising confidentiality, integrity, and availability of the workstation.
Affected Products
- Siemens Solid Edge SE2025 (all versions prior to V225.0 Update 15)
- Siemens Solid Edge SE2026 (all versions prior to V226.0 Update 7)
- DFT file parsing component within Solid Edge

Technical Details for CVE-2026-50060
Vulnerability Analysis
The vulnerability is a use-after-free condition in the Solid Edge DFT file parser. Solid Edge uses DFT files to store draft documents containing 2D drawings and annotations. When the parser processes a crafted DFT file, it references memory that has already been freed, resulting in undefined behavior.
An attacker who controls the freed memory region can hijack execution flow. Because the vulnerable code runs in the user context, code execution inherits the privileges of the logged-on Solid Edge user. The attack requires the user to open the malicious file, so social engineering or supply-chain delivery of DFT assets is the likely exploitation path.
Root Cause
The root cause is improper memory lifecycle management within the DFT parsing routines, classified as [CWE-416] Use After Free. The application retains and dereferences a pointer to a heap object after the underlying allocation has been released. Attackers can shape heap state to place attacker-controlled data at the freed location, transforming the dangling pointer into a controlled read, write, or call primitive.
Attack Vector
Exploitation is local and requires user interaction. An attacker crafts a malicious DFT file and delivers it to a target through email attachments, shared engineering repositories, or compromised project archives. When the victim opens the file in a vulnerable Solid Edge version, the parser triggers the use-after-free condition and executes attacker-supplied code.
No authentication is required beyond the victim's own session on the workstation. See the Siemens Security Advisory SSA-621657 for technical details from the vendor.
Detection Methods for CVE-2026-50060
Indicators of Compromise
- Unexpected crashes of the Solid Edge process (Edge.exe) when opening DFT files, particularly from untrusted sources
- DFT files arriving via email, external file shares, or download from unverified web sources
- Solid Edge spawning unusual child processes such as cmd.exe, powershell.exe, or script interpreters
- Outbound network connections initiated by the Solid Edge process to unfamiliar hosts following DFT file open events
Detection Strategies
- Monitor endpoint telemetry for anomalous child-process creation from Solid Edge binaries, which is atypical for CAD workflows
- Alert on Solid Edge process crashes correlated with recently opened DFT files to surface exploitation attempts and failed attempts
- Inspect email gateways and file-sharing platforms for inbound DFT attachments from external senders
- Correlate Solid Edge process activity with file-write and memory-region-protection changes indicative of shellcode staging
Monitoring Recommendations
- Enable command-line and process-lineage logging on engineering workstations running Solid Edge
- Retain crash dumps from Solid Edge to support post-incident analysis and reverse engineering of malicious DFT samples
- Track installed Solid Edge versions across the fleet and flag hosts still running versions prior to V225.0 Update 15 or V226.0 Update 7
How to Mitigate CVE-2026-50060
Immediate Actions Required
- Update Solid Edge SE2025 to V225.0 Update 15 or later on all affected workstations
- Update Solid Edge SE2026 to V226.0 Update 7 or later on all affected workstations
- Instruct users to open DFT files only from trusted internal sources and to verify the origin of externally received files
- Inventory engineering workstations and prioritize patching for systems that regularly process externally sourced CAD files
Patch Information
Siemens released fixed versions addressing CVE-2026-50060. Apply Solid Edge SE2025 V225.0 Update 15 or Solid Edge SE2026 V226.0 Update 7. Refer to the Siemens Security Advisory SSA-621657 for download locations and release notes.
Workarounds
- Restrict opening of DFT files to those originating from trusted, authenticated internal engineering repositories
- Apply file-type inspection at email and web gateways to quarantine unsolicited DFT attachments
- Segregate CAD workstations from general-purpose network zones to limit lateral movement following a successful exploitation
- Enforce least privilege on engineering user accounts so that code executed in the Solid Edge context has limited system reach
