Details

Improper Authorization vulnerability in OTRS AG OTRS 8 (Websocket API backend) allows any as Agent authenticated attacker to track user behaviour and to gain live insight into overall system usage. User IDs can easily be correlated with real names e. g. via ticket histories by any user. (Fuzzing for garnering other adjacent user/sensitive data). Subscribing to all possible push events could also lead to performance implications on the server side, depending on the size of the installation and the number of active users. (Flooding)This issue affects OTRS: from 8.0.X before 8.0.32.

Vulnerability from github – Published: 2026-03-12 14:22 – Updated: 2026-06-05 17:51

Summary
Copyparty ftp/sftp: Sharing a single file did not fully restrict source-folder access
Details

There was a missing permission-check in the shares feature (the shr global-option).

This vulnerability only applies in the following scenario: * The shares feature is used for the specific purpose of creating a share of just a single file inside a folder * Either the FTP or SFTP server is enabled, and also made publically accessible * If a share is password-protected, then SFTP was not vulnerable unless the sftp-pw global-option was also enabled

Given these conditions, when a user is browsing a share through either FTP or SFTP (not http or https), they can gain read-access to the remaining files inside the shared folder by guessing/bruteforcing the filenames.

It was not possible to descend into subdirectories in this manner; only the sibling files were accessible.

This issue did not affect filekeys or dirkeys.

This vulnerability is CVE-2025-58753 which was previously fixed for HTTP and HTTPS, but not for FTP. The FTPS server did not yet exist at that time.

GHSA-68F8-9MHJ-H2MP

Vulnerability from github – Published: 2026-03-30 18:41 – Updated: 2026-04-10 19:45
VLAI
Summary
OpenClaw has a Gateway HTTP /v1/models Route Bypasses Operator Read Scope
Details

Fixed in OpenClaw 2026.3.24, the current shipping release.

Summary

The OpenAI-compatible HTTP endpoint /v1/models accepts bearer auth but does not enforce operator method scopes.

In contrast, the WebSocket RPC path enforces operator.read for models.list.

A caller connected with operator.approvals (no read scope) is rejected for models.list (missing scope: operator.read) but can still enumerate model metadata through HTTP /v1/models.

Confirmed on current main at commit 06de515b6c42816b62ec752e1c221cab67b38501.

Details

The WS control-plane path enforces role/scope checks centrally before dispatching methods. For non-admin operators, this includes required method scopes such as operator.read for models.list.

The HTTP compatibility path for /v1/models performs bearer authorization and then returns model metadata; it does not apply an equivalent scope check.

As reproduced, a caller with only operator.approvals can:

  1. connect successfully,
  2. fail models.list over WS with missing scope: operator.read,
  3. fetch /v1/models over HTTP with status 200 and model data.

This is a cross-surface authorization inconsistency where the stricter WS policy can be bypassed via HTTP.

Impact

  • Callers lacking operator.read can still enumerate gateway model metadata through HTTP compatibility routes.
  • Breaks scope model consistency between WS RPC and HTTP surfaces.
  • Weakens least-privilege expectations for operators granted non-read scopes.

Patch Suggestion

1) Enforce read scope on /v1/models routes

Apply a scope gate equivalent to models.list before serving /v1/models or /v1/models/:id.

2) Reuse centralized scope-authorization helper for HTTP compatibility endpoints

Use the same operator scope logic used by WS dispatch (authorizeOperatorScopesForMethod(...)) to prevent policy drift.

3) Add regression tests

Keep this PoC and add explicit negative/positive controls:

  • operator.approvals without read is rejected on HTTP /v1/models.
  • operator.read is accepted on both WS models.list and HTTP /v1/models.

Summary
File Browser has an Authorization Policy Bypass in Public Share Download Flow
Details

Summary

A permission enforcement flaw allows users without download privileges (download=false) to still expose and retrieve file content via public share links when they retain share privileges (share=true). This bypasses intended access control policy and enables unauthorized data exfiltration to unauthenticated users. Where download restrictions are used for data-loss prevention or role separation.

Details

The backend applies inconsistent authorization checks across download paths:

As a result, a user who is blocked from direct downloads can create a share and obtain the same file via /api/public/dl/<hash>.

PoC

  1. Create a non-admin user with:
  2. perm.share = true
  3. perm.download = false

  4. Login as that user and upload a PDF file:

  5. POST /api/resources/nodl_secret_<rand>.pdf with Content-Type: application/pdf

  6. Verify direct raw download is denied:

  7. GET /api/raw/nodl_secret_<rand>.pdf
  8. Expected and observed: 202 Accepted (blocked)

  9. Create share for same file:

  10. POST /api/share/nodl_secret_<rand>.pdf
  11. Observed: 200, response includes hash (example: qxfK3JMG)

  12. Download publicly without authentication:

  13. GET /api/public/dl/<hash>
  14. Observed (vulnerable): 200, Content-Type: application/pdf, and PDF bytes are returned

Live evidence captured (March 1, 2026): - create user: 201 - create file: 200 - direct /api/raw: 202 Accepted - create share: 200 - public download /api/public/dl/mxK-ppZb: 200 - public download content-type: application/pdf - public download body length: 327 bytes

Impact

This is an access control / authorization policy bypass vulnerability.

  • Who can exploit: Any authenticated user granted share=true but denied download.
  • Who is impacted: Operators and organizations relying on download restrictions to prevent data export.
  • What can happen: Restricted users can still distribute and retrieve files publicly, including unauthenticated access through share URLs.

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.
