Advisory FAQ

How do I know if I am affected?

If you have a runtime or SDK with a version listed, or an affected package listed in affected software or affected packages, you're exposed to the vulnerability.

How do I fix the issue?

  • To fix the issue please install the latest version of .NET 9.0 or .NET 8.0. If you have installed one or more .NET SDKs through Visual Studio, Visual Studio will prompt you to update Visual Studio, which will also update your .NET SDKs.
  • If you have .NET 6.0 or greater installed, you can list the versions you have installed by running the dotnet --info command. You will see output like the following;

Vulnerability from github – Published: 2026-07-07 20:56 – Updated: 2026-07-20 19:24
VLAI
Summary
@better-auth/oauth-provider's OAuth authorization-code grant allows concurrent redemption when two token requests race the find-then-delete primitive
Details

Am I affected?

Users are affected if all of the following are true:

  • Their project depends on @better-auth/oauth-provider at a version >= 1.6.0, < 1.6.11, or uses the embedded plugin in better-auth >= 1.4.8-beta.7, < 1.6.0, or enables the legacy oidc-provider or mcp plugins from better-auth/plugins.
  • Their application exposes /api/auth/oauth2/token (or the legacy plugins' /oauth2/token and /mcp/token) as a token endpoint to OAuth/OIDC clients, including internal MCP clients (Claude Desktop, custom MCP tool callers, AI agents).
  • Their application has not implemented an external mitigation: a load-balancer-level idempotency cache keyed by code, a database trigger that rejects duplicate token issuance for the same authorization code, or a custom adapter override that performs an atomic compare-and-delete.

Fix:

  1. Upgrade to @better-auth/oauth-provider@1.6.11 or later. If developers use the legacy plugin paths from better-auth/plugins, upgrade better-auth to 1.6.11 or later.
  2. If developers cannot upgrade, see workarounds below.

Summary

The OAuth provider's POST /oauth2/token endpoint, on the authorization_code grant, redeems a single-use authorization code through a non-atomic find-then-delete sequence. Two concurrent requests with the same code value both pass the read step before either delete completes, then both proceed to PKCE verification and createUserTokens. Each surviving request mints a fresh access token, refresh token, and id token. RFC 6749 §4.1.2 requires authorization codes to be single-use; this primitive does not enforce that under concurrency.

Details

The same architectural primitive (find a single-use verification row, then delete it, then trust the row to authorize) is used in 20 other call sites across the codebase. The deletion primitive returns Promise<void>, discarding the row count surfaced by adapter.deleteMany, so no call site can detect "another caller already claimed this row". The fix lands at the primitive layer rather than at any individual call site.

The fix introduces a claimVerificationByIdentifier primitive at the internal-adapter layer that performs an atomic claim-and-return, replaces the find-then-delete pair at this call site, and migrates the highest-impact variant sites in the same release.

Patches

Fixed in @better-auth/oauth-provider@1.6.11 and better-auth@1.6.11 for the legacy oidc-provider and mcp plugin paths. All three token-exchange call sites now consume the verification row through internalAdapter.consumeVerificationValue, an atomic claim primitive that deletes the row and returns its prior value in one operation. The first request to arrive takes the row and mints tokens; concurrent racers observe an empty result and return invalid_grant.

Error-code consistency is also tightened on the @better-auth/oauth-provider token endpoint: the malformed-verification-value branches previously returned a project-specific invalid_verification code, which is not part of RFC 6749 §5.2's response error set. Both branches now return invalid_grant so spec-compliant clients can branch on the standard code without a special case.

Workarounds

None of these close the bug fully without a code patch. Upgrading is the only good path.

  • Network-layer: deploy an authorization-server-aware reverse proxy (Envoy, NGINX with Lua, custom Cloudflare Worker) that holds an in-flight registry keyed by the code parameter and serializes concurrent requests for the same code. Fragile under multi-instance deployments unless the registry is shared (Redis-backed).
  • Database-layer: add a SQL or Mongo uniqueness constraint that prevents two oauthAccessToken rows from being created with the same upstream code reference. Adapter-specific and not always feasible since the schema does not currently store the source code.
  • Application-layer: wrap deleteVerificationByIdentifier with a custom hook that uses adapter.deleteMany and surfaces the count, then injects an invalid_grant rejection when the count is zero. Requires forking the internal adapter.

Impact

  • Multiple independent token sets from a single authorization: forked access tokens, refresh tokens, and id tokens issued from the same code, all valid for the original user's authorization scope.
  • Detection bypass: standard OAuth single-use enforcement does not fire for the second redemption when both requests interleave through the read step.
  • Legacy-plugin reach: oidc-provider and mcp plugins share the primitive on the same surface, so deployments using them inherit the same impact.

Details

deepin-clone before 1.1.3 uses a predictable path /tmp/.deepin-clone/mount/ in the Helper::temporaryMountDevice() function to temporarily mount a file system as root. An unprivileged user can prepare a symlink at this location to have the file system mounted in an arbitrary location. By winning a race condition, the attacker can also enter the mount point, thereby preventing a subsequent unmount of the file system.

Mitigation
Architecture and Design

In languages that support it, use synchronization primitives. Only wrap these around critical code to minimize the impact on performance.

Mitigation
Architecture and Design

Use thread-safe capabilities such as the data access abstraction in Spring.

Mitigation
Architecture and Design
  • Minimize the usage of shared resources in order to remove as much complexity as possible from the control flow and to reduce the likelihood of unexpected conditions occurring.
  • Additionally, this will minimize the amount of synchronization necessary and may even help to reduce the likelihood of a denial of service where an attacker may be able to repeatedly trigger a critical section (CWE-400).
Mitigation
Implementation

When using multithreading and operating on shared variables, only use thread-safe functions.

Mitigation
Implementation

Use atomic operations on shared variables. Be wary of innocent-looking constructs such as "x++". This may appear atomic at the code layer, but it is actually non-atomic at the instruction layer, since it involves a read, followed by a computation, followed by a write.

Mitigation
Implementation

Use a mutex if available, but be sure to avoid related weaknesses such as CWE-412.

Mitigation
Implementation

Avoid double-checked locking (CWE-609) and other implementation errors that arise when trying to avoid the overhead of synchronization.

Mitigation
Implementation

Disable interrupts or signals over critical parts of the code, but also make sure that the code does not go into a large or infinite loop.

Mitigation
Implementation

Use the volatile type modifier for critical variables to avoid unexpected compiler optimization or reordering. This does not necessarily solve the synchronization problem, but it can help.

Mitigation MIT-17
Architecture and Design Operation

Strategy: Environment Hardening

Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.

CAPEC-26: Leveraging Race Conditions

The adversary targets a race condition occurring when multiple processes access and manipulate the same resource concurrently, and the outcome of the execution depends on the particular order in which the access takes place. The adversary can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance, a race condition can occur while accessing a file: the adversary can trick the system by replacing the original file with their version and cause the system to read the malicious file.

CAPEC-29: Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions

This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. A typical example is file access. The adversary can leverage a file access race condition by "running the race", meaning that they would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the adversary could replace or modify the file, causing the application to behave unexpectedly.
