Summary
Snipe-IT has Privilege Escalation via API Permissions Assignment
Details

Impact

An authenticated user with only users.edit permission can escalate their own privileges to admin by sending a PATCH request to /api/v1/users/{id} with permissions[admin]=1. The API controller only strips the superuser key from the permissions array, allowing admin and all other permission keys to be set by any user who can update users.

Patches

Patched in https://github.com/grokability/snipe-it/commit/ce18ff669ceb0f0349749fd5d11c1d3d40b10569, fix was released in v8.4.1

Workarounds

None.

Summary
Cloudreve OAuth Admin.Read scope can update OneDrive storage policy credentials
Details

Summary

Cloudreve 4.16.1 has an OAuth scope authorization bypass in the admin storage policy routes. An OAuth bearer token scoped to Admin.Read but not Admin.Write can call POST /api/v4/admin/policy/oauth/signin and update OneDrive storage policy credentials.

The route is inside the admin group that requires Admin.Read, but it does not add the local Admin.Write guard used by sibling policy mutation routes. Its handler persists attacker-supplied secret and app_id values into the selected OneDrive storage policy before returning an OAuth URL.

Impact

An OAuth application that was granted only read-only admin scope can modify persistent storage backend configuration for a OneDrive policy. This can break the storage backend, replace the stored application secret and app ID, and redirect future OAuth setup for that policy to attacker-controlled application parameters. The attack crosses the intended OAuth scope boundary because Admin.Write is required for sibling storage policy mutation routes.

Reproduction

Preconditions:

  1. The instance has a OneDrive storage policy.
  2. An admin user authorizes an OAuth client for Admin.Read but not Admin.Write.
  3. The OAuth client obtains a bearer access token for that admin user.

Send the following request with that read-only admin scoped token:

POST /api/v4/admin/policy/oauth/signin HTTP/1.1
Authorization: Bearer <admin OAuth token scoped to Admin.Read only>
Content-Type: application/json

{"id":1,"secret":"attacker-secret","app_id":"attacker-app-id"}

Expected secure result: the request is rejected with an insufficient-scope error because it changes storage policy credentials.

Actual result: the request reaches AdminOdOAuthURL, and GetOauthRedirectService.GetOAuth() persists the supplied values to the storage policy.

Root cause

routers/router.go applies RequiredScopes(types.ScopeAdminRead) to the authenticated admin route group. Sibling policy mutation routes add local RequiredScopes(types.ScopeAdminWrite) guards, for example policy create, policy update, CORS creation, OAuth callback, and policy delete.

The OneDrive OAuth signin route is missing that local write-scope guard:

oauth.POST("signin",
    controllers.FromJSON[adminsvc.GetOauthRedirectService](adminsvc.GetOauthRedirectParamCtx{}),
    controllers.AdminOdOAuthURL,
)

The handler performs a persistent write in service/admin/policy.go:

policy.Settings.OauthRedirect = routes.MasterPolicyOAuthCallback(dep.SettingProvider().SiteURL(c)).String()
policy.SecretKey = service.Secret
policy.BucketName = service.AppID
policy, err = storagePolicyClient.Upsert(c, policy)

The request fields secret and app_id come directly from the caller.

PoC evidence

A focused scope test confirmed that a request context with only Admin.Read fails CheckScope(c, types.ScopeAdminWrite), while Admin.Write implies Admin.Read. Therefore write routes must add RequiredScopes(types.ScopeAdminWrite) explicitly. The vulnerable route does not do so, and the handler writes the policy fields shown above.

Remediation

Add middleware.RequiredScopes(types.ScopeAdminWrite) to oauth.POST("signin", ...) before the JSON handler. Consider auditing other admin test routes that perform outbound network or mail actions under only Admin.Read, but this persistent credential update should be fixed first.

Vulnerability from github – Published: 2025-05-22 21:30 – Updated: 2025-05-22 21:30
VLAI
Details

An incorrect authorization vulnerability exists in multiple WSO2 products due to a business logic flaw in the account recovery-related SOAP admin service. A malicious actor can exploit this vulnerability to reset the password of any user account, leading to a complete account takeover, including accounts with elevated privileges.

This vulnerability is exploitable only through the account recovery SOAP admin services exposed via the "/services" context path in affected products. The impact may be reduced if access to these endpoints has been restricted based on the "Security Guidelines for Production Deployment" by disabling exposure to untrusted networks.

Severity
9.8 (Critical)

Vulnerability from github – Published: 2026-05-18 09:31 – Updated: 2026-06-01 15:53

Summary
Mattermost doesn't validate that the RefreshedToken differs from the original invite token during remote cluster invite confirmation
Details

Mattermost versions 11.5.x <= 11.5.1, 10.11.x <= 10.11.13 fail to validate that the RefreshedToken differs from the original invite token during remote cluster invite confirmation which allows an authenticated attacker to bypass token rotation and reuse the original invite token via sending a crafted invite confirmation with a RefreshedToken matching the original token. Mattermost Advisory ID: MMSA-2026-00575

Mitigation
Architecture and Design
  • Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
  • Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design

Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].

Mitigation MIT-4.4
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
  • For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
  • One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration Installation

Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
