Security readout for executives and security teams
Plain-English summary
Inkscape 0.91 contains a memory corruption flaw that could let an attacker run code if a user interacts with malicious content. Business risk is highest where legacy Inkscape is used on workstations tied to design, engineering, or SCADA graphics workflows.
Executive priority
Treat as a high-priority legacy software exposure, especially in operational technology or engineering environments. The issue is not marked as actively exploited in the supplied data, but successful exploitation could compromise the user workstation.
Technical view
CVE-2021-42704 is a CWE-787 out-of-bounds write in Inkscape 0.91. The CVSS 3.1 score is 7.8 with local attack vector, low complexity, no privileges required, required user interaction, unchanged scope, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to environments still running Inkscape 0.91. The cited references connect this risk to Inkscape and IntegraXor SCADA animation graphic editor usage; affected deployment details beyond version 0.91 are not provided.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation. The CVSS vector indicates exploitation requires local context and user interaction, so malicious file handling or graphics workflow abuse is the main concern, but no exploit path is specified.
Researcher notes
The public bundle identifies Inkscape 0.91, CWE-787, and potential arbitrary code execution, but does not include root cause details, proof-of-concept status, affected file formats, or fixed-version information. Avoid assuming broader affected versions without vendor confirmation.
Mitigation direction
- Inventory endpoints and engineering systems for Inkscape 0.91.
- Check Inkscape, IntegraXor, and CISA guidance for fixed versions or mitigations.
- Restrict use of Inkscape 0.91 with untrusted graphics files.
- Remove unsupported legacy installations where business workflows allow.
- Prioritize controls on SCADA-adjacent graphics authoring workstations.
Validation and detection
- Verify installed Inkscape versions across endpoints and build images.
- Identify workflows using the IntegraXor Inkscape extension.
- Confirm whether users process externally supplied graphics files.
- Review vendor advisories for remediation status and version guidance.
- Document any systems requiring compensating controls pending upgrade.

Out-of-bounds Write
Out-of-bounds Write represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
