CVE-2026-25883
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 · uneditedVexa is an open-source, self-hostable meeting bot API and meeting transcription API. Prior to 0.10.0-260419-1910, the Vexa webhook feature allows authenticated users to configure an arbitrary URL that receives HTTP POST requests when meetings complete. The application performs no validation on the webhook URL, enabling Server-Side Request Forgery (SSRF). An authenticated attacker can set their webhook URL to target internal services (Redis, databases, admin panels), cloud metadata endpoints (AWS/GCP credential theft), and/or localhost services. Version 0.10.0-260419-1910 patches the issue.
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 · high confidenceThe Vexa application prior to version 0.10.0-260419-1910 contains a Server-Side Request Forgery (SSRF) vulnerability in its webhook configuration feature. Authenticated users can specify any URL for the meeting completion webhook without validation, allowing attackers to make the server perform requests to internal services, cloud metadata endpoints (e.g., AWS IMDS at 169.254.169.254), or localhost services.

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.
-
Identify installed Vexa versionLocate the Vexa application version through its package manager, about dialog, or version command (e.g., vxa --version, or check installation directory for version metadata)Affected if The installed version is 0.10 or any version lower than 0.10.0-260419-1910
-
Determine if webhook configuration is accessibleVerify whether the authenticated user has access to the webhook configuration settings within the Vexa administrative interface or API endpointAffected if The webhook configuration feature is enabled and accessible to authenticated users
-
Inspect webhook URL validation settingsExamine the webhook configuration file or API response for the meeting completion webhook to determine if URL validation is implemented (look for allowlists, blocklists, or validation logic)Affected if No URL validation is present, or validation does not explicitly block private IP ranges (10.x, 192.168.x, 172.16-31.x), localhost (127.0.0.1), and cloud metadata endpoints (169.254.169.254)
-
Check for recent webhook requests to internal destinationsReview webhook delivery logs, server access logs, or network traffic for outbound requests from the Vexa server to internal IPs, localhost, or known metadata endpointsAffected if Outbound webhook requests have been made to internal services, localhost, or 169.254.169.254
You are affected if your Vexa installation is version 0.10 or lower AND the webhook configuration feature is enabled and accessible without strict URL validation that blocks internal destinations.

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 · scopedUpgrade to version 0.10.0-260419-1910 or implement strict URL validation/allowlisting that blocks access to private IP ranges, localhost, and cloud metadata endpoints.
0.10.0-260419-1910
- Upgrade Vexa to version 0.10.0-260419-1910 or later
- Verify the upgrade was successful by checking the application version
- Confirm webhook URL validation is now enforced by testing with an internal URL (should be rejected)
