Title
OpenProject: Improper Access Control through /api/v3/custom_options/:id via Path "id" leads to Sensitive Data Exposure
Summary
OpenProject is open-source, web-based project management software. Prior to 17.6.0, GET /api/v3/custom_options/:id resolved CustomOption records by global numeric id and allowed UserCustomField and GroupCustomField options without checking visible(current_user), so authenticated non-admin users could enumerate sequential custom option ids and read labels belonging to admin_only user or group custom fields. This issue is fixed in 17.6.0.

Title
OliveTin: StartActionAndWait Endpoints Bypass `logs` Permission and Return Action Output
Summary
OliveTin gives safe and simple access to predefined shell commands from a web interface. Prior to 3000.17.0, the service/internal/api/api.go StartActionAndWait and StartActionByGetAndWait endpoints return full LogEntry output after execution without enforcing the logs permission, allowing a user with exec permission but logs:false to read action output. This issue is fixed in version 3000.17.0.

Title
RabbitMQ: Web MQTT with PROXY Protocol enabled: a loopback-only user permission bypass
Summary
RabbitMQ is a messaging and streaming broker. From 3.13.0 until 3.13.18, 4.0.23, 4.1.14, 4.2.9, and 4.3.3, native MQTT and MQTT over WebSocket behind a trusted PROXY Protocol frontend could lose the proxy-derived client address before the MQTT authentication path checked loopback_users, causing the frontend-to-broker address to be treated as loopback. An attacker who can reach the trusted frontend and has valid credentials for a loopback-restricted account can therefore bypass the source-address restriction; the issue does not bypass password authentication. This issue is fixed in versions 3.13.18, 4.0.23, 4.1.14, 4.2.9, and 4.3.3.

From 3.13.0 until 3.13.18, 4.0.23, 4.1.14, 4.2.9, and 4.3.3, native MQTT and MQTT over WebSocket behind a trusted PROXY Protocol frontend could lose the proxy-derived client address before the MQTT authentication path checked loopback_users, causing the frontend-to-broker address to be treated as loopback. An attacker who can reach the trusted frontend and has valid credentials for a loopback-restricted account can therefore bypass the source-address restriction; the issue does not bypass password authentication. This issue is fixed in versions 3.13.18, 4.0.23, 4.1.14, 4.2.9, and 4.3.3."

Title
Vendure 3.7.1 Cross-Channel Authorization Bypass via StockLocation and Asset Update
Summary
Vendure through 3.7.1, fixed in commit f67ef5f, contains a cross-channel authorization bypass vulnerability in stock-location.service.ts and asset.service.ts update methods that allows channel-scoped administrators to modify other tenants' data. Attackers can supply global IDs of StockLocation or Asset entities from different channels to overwrite inventory locations or catalog assets belonging to other tenants without proper channel isolation validation.

ArcadeDB before 26.7.2 Authorization Bypass via SQL DEFINE FUNCTION
Summary
ArcadeDB versions before 26.7.2 fail to enforce scripting authorization checks on the SQL DEFINE FUNCTION statement with LANGUAGE js. Attackers with database access can execute arbitrary JavaScript code by submitting DEFINE FUNCTION statements, bypassing security controls intended to restrict scripting to administrators.

CVE-2026-67310 (GCVE-0-2026-67310)

Vulnerability from cvelistv5 – Published: 2026-08-01 12:22 – Updated: 2026-10-08 15:51
VLAI
Title
openremote before 1.27.0 Cross-Tenant IDOR via setAssetLinks
Summary
OpenRemote (org.openremote:openremote) versions <= 1.26.2 contain an insecure direct object reference vulnerability in the setAssetLinks endpoint of AlarmResourceImpl. The realm access check validates only a single realm obtained via realms.stream().findFirst() on a HashSet of realms from the request, rather than all realms. Because HashSet iteration order is non-deterministic, an authenticated attacker who includes alarm-asset links from both their own realm and a victim realm can, with roughly 50% probability per request (retryable), persist cross-tenant links and disclose victim asset names (returned via @Formula fields) through GET requests on the attacker's own alarm. Fixed in 1.27.0.

Title
BookStack < 26.05.4 Broken Access Control via Image Gallery API
Summary
BookStack before 26.05.4 contains a broken access control vulnerability that allows authenticated API users with image-update or image-delete permissions to manipulate other users' avatars by exploiting missing content-type restrictions in the Image Gallery API endpoints. Attackers can supply a user avatar's ID to the API controller, which loads any image type without the web controller's gallery and drawio restrictions, and when the avatar's uploaded_to field matches a page ID accessible to the attacker, the authorization check passes allowing the attacker to rename, replace, or delete the target user's avatar without requiring user-management permission.

CVE-2026-66853 (GCVE-0-2026-66853)

Vulnerability from cvelistv5 – Published: 2026-10-14 14:36 – Updated: 2026-10-14 15:17

Title
Gitea restricted-user organization metadata disclosure
Summary
Gitea's user organization-list API includes Limited-visibility organizations for authenticated restricted accounts without applying the visibility restriction enforced by the single-organization endpoint. A restricted user can list a known user's public organization memberships and retrieve limited organizations' names, descriptions, and avatars. This exposes organization metadata that should be hidden from the requesting account.

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.
