Security readout for executives and security teams
Plain-English summary
CVE-2021-41810 is a script injection issue in M-Files Admin before version 22.2.11051.0. A vault administrator could store script-bearing configuration data that later runs when another vault administrator uses the admin tool. This is not remotely exploitable and requires high privilege, but it can affect sensitive administrative workflows.
Executive priority
Handle in normal patch governance, with higher urgency for environments where many vault administrators share access. The issue is not remotely exploitable, but it sits inside privileged administration and can expose sensitive data.
Technical view
The issue is CWE-79 stored script injection in M-Files Admin configuration handling. Sources describe versions before 22.2.11051.0 as affected. CVSS 3.1 is 5.2 with PR:H and UI:R, with potential high confidentiality impact, low integrity impact, and no availability impact.
Likely exposure
Exposure is most likely in M-Files Server/Admin deployments below 22.2.11051.0 where multiple vault administrators manage the same vault. Risk is constrained by required vault admin authentication and admin-tool interaction.
Exploitation context
The source bundle says the issue requires vault admin level authentication and is not remotely exploitable. KEV is false, and no provided source reports active exploitation. Treat exploitation evidence as absent, not impossible.
Researcher notes
The affected entry names M-Files Server, while the vulnerability text specifically describes M-Files Admin. Validate exposure against vendor advisory language. Avoid treating the network CVSS component as remote exploitability because the source explicitly states it is not remotely exploitable.
Mitigation direction
- Upgrade affected M-Files deployments to 22.2.11051.0 or later.
- Review the vendor advisory for exact product and deployment guidance.
- Limit vault administrator access to trusted, necessary personnel.
- Review administrative configuration data for unexpected script-bearing content.
Validation and detection
- Inventory M-Files Server/Admin versions across managed environments.
- Confirm no deployment remains below 22.2.11051.0.
- Verify vault administrator membership is current and justified.
- Check recent admin configuration changes for unexpected script content.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
