Security readout for executives and security teams
Plain-English summary
Flask-AppBuilder before 4.1.3 allowed an authenticated Admin user to infer parts of other users' salted password hashes through query filtering. The hashes were not directly returned, but the behavior could leak sensitive account metadata. The issue is low severity because it requires high privileges.
Executive priority
Treat as a low-priority but real confidentiality issue. Schedule upgrade through normal maintenance unless Admin access is widely distributed or weakly controlled, in which case prioritize access review and patching sooner.
Technical view
CVE-2022-31177 is a CWE-200 information exposure flaw in Flask-AppBuilder user querying. Before 4.1.3, an authenticated Admin could filter users using partial salted and hashed password strings, allowing inference of partial password hashes mapped to users. CVSS is 2.7: network reachable, low complexity, high privileges required, confidentiality impact low.
Likely exposure
Exposure is limited to applications using Flask-AppBuilder versions earlier than 4.1.3, especially deployments where Admin access is broadly granted, shared, or at risk of compromise. The source bundle does not identify affected downstream products or managed services.
Exploitation context
The sources do not report active exploitation, and CISA KEV is false. Abuse requires an authenticated Admin user. The impact is information disclosure only; sources do not claim password recovery, privilege escalation, integrity impact, or availability impact.
Researcher notes
Evidence is clear on affected range, privilege requirement, impact type, and fixed version. Public sources do not provide exploit status, downstream product mapping, or workarounds. Avoid assuming broader password compromise from the advisory alone.
Mitigation direction
- Upgrade Flask-AppBuilder to version 4.1.3 or later.
- Review vendor advisory and release notes before rollout.
- Restrict Admin access to trusted, necessary users only.
- Audit Admin accounts and remove stale or shared access.
- If upgrade is delayed, check vendor guidance; sources state no known workaround.
Validation and detection
- Inventory Flask-AppBuilder versions in lockfiles, images, and deployed environments.
- Confirm production and non-production deployments run version 4.1.3 or later.
- Review who has Flask-AppBuilder Admin privileges.
- Check application logs for unusual Admin user-search activity.
- Verify dependency scanners flag versions earlier than 4.1.3.

CWE-200: Information exposure and cloud metadata lookup
Information exposure and SSRF weaknesses can make discovery, cloud metadata, and credential material review relevant. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupCredential and access behavior lookup
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.

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.
