Security readout for executives and security teams
Plain-English summary
CVE-2022-4862 is an authenticated-user XSS issue in M-Files New Web before 22.12.12140.3. Content provided by one authenticated user could be rendered as HTML in another user’s browser, creating a risk of sensitive information theft.
Executive priority
Treat as a moderate confidentiality risk. It is not presented as remotely unauthenticated or actively exploited, but it affects sensitive document workflows where stolen user data could have business impact.
Technical view
The CVE describes browser-side rendering of HTML supplied by another authenticated user in M-Files Web/New Web before 22.12.12140.3. The CVSS 3.1 score is 5.0, with low privileges and user interaction required, high confidentiality impact, low integrity impact, and no availability impact.
Likely exposure
Exposure is likely limited to organizations running M-Files New Web versions earlier than 22.12.12140.3, especially where multiple authenticated users exchange or view user-controlled content through the web interface.
Exploitation context
The source bundle does not identify public exploitation, and the CVE is not listed as KEV. Exploitation requires an authenticated user, user interaction, and conditions where attacker-provided HTML is rendered in another user’s browser.
Researcher notes
Evidence is sparse. Sources identify the affected product and fixed version threshold, but provide limited detail on exact rendering paths, affected configurations, or exploit prerequisites beyond authenticated content and user interaction. The CVE record maps this to CWE-200.
Mitigation direction
- Upgrade M-Files New Web to 22.12.12140.3 or later.
- Review M-Files vendor advisories for deployment-specific guidance.
- Limit access to M-Files Web until affected versions are remediated.
- Prioritize users or vaults handling sensitive business information.
Validation and detection
- Inventory deployed M-Files New Web versions.
- Confirm no production instance is below 22.12.12140.3.
- Check whether authenticated users can submit content viewed by others.
- Review vendor advisory status against your deployment model.

Exposure of Sensitive Information to an Unauthorized Actor
Exposure of Sensitive Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
