CVE-2026-59705
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 · uneditedmem0's openmemory/api component contains an unauthenticated access vulnerability that allows unauthenticated attackers to read, write, and delete arbitrary user memories by accessing API routers registered without authentication middleware. Attackers can supply arbitrary user_id parameters or directly access memory retrieval endpoints to expose private memory content, or invoke pause endpoints with global_pause=true to cause denial-of-service across all users.
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 confidencemem0's openmemory/api component has a critical authentication bypass vulnerability where API routers are registered without authentication middleware. Unauthenticated attackers can read, write, and delete arbitrary user memories by supplying arbitrary user_id parameters or directly accessing memory retrieval endpoints, and can invoke pause endpoints with global_pause=true to cause denial-of-service across all users.

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 mem0 installation and versionRun 'pip show mem0' or check your package manager for the installed mem0 version. Compare this version against any release notes or changelogs for your deployment.Affected if The installed version contains the openmemory/api component and the version is unpatched for authentication bypass vulnerabilities.
-
Locate openmemory API router definitionsSearch your codebase or installed package for API router files in the openmemory/api module. Look for files like 'routes.py', 'api.py', or similar router definitions within the openmemory directory structure.Affected if The openmemory/api component is present in your deployment.
-
Inspect API router middleware configurationExamine the router definition files and any main API application file that includes these routers. Look for statements that register routers (such as 'include_router' in FastAPI/Starlette) and check if authentication middleware or dependency injection (for example, 'Depends(auth_required)') is applied to those router inclusions.Affected if Routers from openmemory/api are registered without any authentication middleware or dependency wrapping.
-
Verify authentication requirements on memory endpointsReview the specific endpoint definitions within the openmemory API routers. Check each endpoint (GET, POST, DELETE for memory operations) for authentication decorators, dependencies, or middleware that enforce authorized access.Affected if Memory operation endpoints (read, write, delete) do not require authentication or user validation.
-
Test unauthenticated API accessSend HTTP requests to the deployed openmemory API endpoints without providing authentication credentials. Try accessing memory retrieval endpoints and memory modification endpoints, optionally supplying arbitrary user_id parameters in requests.Affected if Requests complete successfully without authentication and allow access to or modification of memory data for arbitrary user IDs.
-
Check for global pause endpoint exposureLocate any pause or administrative endpoints within the openmemory API. Determine if these endpoints accept a 'global_pause' parameter and whether they are accessible without authentication.Affected if Pause or administrative endpoints are accessible without authentication and accept global_pause=true to affect all users.
Your environment is affected if the openmemory/api component is deployed with API routers registered without authentication middleware, allowing unauthenticated access to memory operations and administrative functions.

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 dataApply authentication middleware to all API routers in the openmemory/api component and implement proper user_id validation/authorization checks to prevent unauthorized memory access and administrative actions.
