CVE-2025-51868
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 · uneditedInsecure Direct Object Reference (IDOR) vulnerability in Dippy (chat.dippy.ai) v2 allows attackers to gain sensitive information via the conversation_id parameter to the conversation_history endpoint.
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 confidenceAn Insecure Direct Object Reference (IDOR) vulnerability in Dippy v2's conversation_history endpoint allows unauthenticated or authenticated attackers to access sensitive conversation data by manipulating the conversation_id parameter without proper authorization validation.

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.
-
Confirm Dippy v2 is installedCheck your application's dependencies (e.g., pip list, package.json, Gemfile, or equivalent) for the Dippy package and note the installed version. Compare against the v2 release lineage.Affected if The application uses Dippy v2 and the version has not yet received the security patch for CVE-2025-51868.
-
Locate the conversation_history endpointReview your application's routing configuration or API specification to identify routes handling /conversation_history or similar paths that expose conversation data.Affected if The conversation_history endpoint is exposed and accessible via HTTP/HTTPS.
-
Verify endpoint accessibilitySend a request to the conversation_history endpoint (e.g., GET /api/conversation_history?conversation_id=1) without credentials or with a low-privilege account.Affected if The endpoint returns data or responds without requiring authentication or failing due to authorization checks.
-
Test for IDOR vulnerabilityIf authenticated, access the endpoint with a conversation_id that does not belong to the requesting user (e.g., increment/decrement the ID). Observe whether unauthorized conversation data is returned.Affected if The application returns conversation data for conversation_ids that the requesting user does not own or have permission to access.
-
Check authorization logicInspect the source code or application logs for the conversation_history handler to verify if object-level authorization (e.g., ownership verification) is performed before returning data.Affected if No ownership or permission check is implemented, or such checks are bypassed/failed.
You are affected if Dippy v2 is running with an unpatched version and the conversation_history endpoint returns conversation data without validating that the requesting user owns or has permission to access the specific conversation_id.

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.
From vendor dataImplement and enforce proper object-level authorization checks to verify the requesting user has permission to access the requested conversation_history resource before returning any data.
