CVE-2025-52219
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSelectZero SelectZero Data Observability Platform before 2025.5.2 contains an Open Redirect vulnerability. Legacy UI fields can be used to create arbitrary external links via HTML Injection.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceSelectZero Data Observability Platform before version 2025.5.2 has an Open Redirect vulnerability in its Legacy UI. Attackers can inject HTML into legacy interface fields to create arbitrary external links, allowing phishing attacks by redirecting users to malicious sites.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed SelectZero versionLocate the version information for your SelectZero installation (typically found in the platform's about page, admin settings, or installation manifest)Affected if The installed version is anything before 2025.5.2 (e.g., 2025.5.1, 2025.4.x, or earlier)
-
Confirm Legacy UI is accessibleAccess the Legacy UI endpoint or interface (often accessible via /legacy, /old-ui, or a dedicated legacy login portal in the application)Affected if The Legacy UI is present and operational in your environment
-
Identify Legacy UI configurationReview the platform configuration files or admin settings for legacy interface options and URL redirect/forwarding settingsAffected if URL redirection or forwarding features are enabled in the Legacy UI configuration
Your environment is affected if you are running any SelectZero version before 2025.5.2 AND the Legacy UI is enabled and accessible to users.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2025.5.2
Upgrade to version 2025.5.2 or later. Until then, disable the Legacy UI or implement strict URL validation/sanitization on all legacy input fields to block external redirects.
2025.5.2 or later
- Identify all deployed instances of SelectZero Data Observability Platform currently running versions prior to 2025.5.2
- Review release notes or change logs from selectzero.io for version 2025.5.2 to confirm the security fix addresses the open redirect vulnerability
- Plan upgrade window and backup current data/configuration
- Upgrade SelectZero to version 2025.5.2 or later following standard upgrade procedures
- Verify the upgrade was successful and test that legacy UI fields no longer permit arbitrary external link creation
- Confirm the open redirect vulnerability is resolved by attempting to inject external URLs in legacy UI fields and verifying they are either blocked or rendered safely
