Security readout for executives and security teams
Plain-English summary
CVE-2026-22602 lets a low-privileged OpenProject user discover other users’ full names in affected versions. This is a privacy and reconnaissance issue, not a system takeover. The vendor rates it low severity and fixed it in OpenProject 16.6.2.
Executive priority
Treat as a routine but privacy-relevant update. Prioritize shared, externally accessible, or partner-facing OpenProject environments. This does not indicate ransomware-level urgency, but delayed remediation may increase phishing and reconnaissance risk.
Technical view
OpenProject before 16.6.2 exposes full names of other users to logged-in low-privileged users. The advisory says predictable sequential user IDs and API behavior allow automated retrieval of names. The issue is CWE-200 information exposure with CVSS 3.1 score 3.5.
Likely exposure
Organizations running OpenProject versions earlier than 16.6.2 are potentially exposed if untrusted or broadly provisioned users can log in. Exposure is greater in internet-accessible or multi-tenant deployments.
Exploitation context
Sources do not report active exploitation, and the CVE is not listed as KEV. Exploitation requires a logged-in low-privileged user. The impact is disclosure of users’ full names, which may aid phishing, social engineering, or account targeting.
Researcher notes
The provided sources identify the affected product, fixed version, and root issue, but do not provide evidence of exploitation in the wild. Avoid assuming broader data exposure beyond full names unless confirmed in your environment or by vendor guidance.
Mitigation direction
- Upgrade OpenProject to version 16.6.2 or later.
- If upgrade is not possible, apply the vendor-provided patch manually.
- Review vendor advisory and release notes before deployment.
- Limit OpenProject accounts to users with a business need.
Validation and detection
- Inventory OpenProject instances and confirm their running versions.
- Flag any OpenProject deployment below 16.6.2 as affected.
- Review whether low-privileged users exist on affected instances.
- Check vendor advisory, pull request, and commit for patch applicability.

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.
