Jeepay through 3.2.9 contains an insecure direct object reference vulnerability that allows authenticated merchant users to delete other merchants' division receivers by exploiting an ownership check on the wrong column. Attackers holding ENT_DIVISION_RECEIVER_DELETE who own a receiver group whose id matches a victim's receiver id can delete the victim's profit-sharing receiver.

GHSA-GFM2-XM6C-37QC

Vulnerability from github – Published: 2026-05-14 20:24 – Updated: 2026-05-15 23:54
VLAI
Summary
Open WebUI has Broken Access Control for Completions API
Details

Summary

Any user X can continue the conversation of any other user Y, as long as the Chat ID of Y is known. User X does not even need to be an admin to do so.

Details

A user just needs to use the API endpoint: /api/chat/completions with their own API key (generated in OWUI) and the Chat ID of another user. OWUI does not check to match the Chat ID with the user that created that Chat ID. Note that both users will need access to the same model. This is especially relevant if there is a shared pipeline model between users.

PoC

  1. Using OWUI v0.6.18
  2. Sign in with any user X
  3. Generate an API Key for user X using the settings
  4. Create another user Y, and have a conversation in OWUI. Copy the Chat ID from the URL.
  5. User X can now use the API /api/chat/completions and the Chat ID from step 4 to continue the conversation of user Y

Impact

Large impact to any user in OWUI. People can read your conversations, and access private information if they know your Chat ID (which is in the URL of the chat).

Resolution

Fixed in commit cf4218e68, first released in v0.9.0 (Apr 2026). The chat_completion handler at backend/open_webui/main.py:1868 now explicitly verifies chat ownership via Chats.is_chat_owner(chat_id, user.id) for any request that targets an existing chat, and raises 404 for non-owners (admin bypass preserved per the documented threat model). New chats (no chat_id supplied, or freshly inserted via the is_new_chat branch) are unaffected. Users on >= 0.9.0 are not affected.

Vulnerability from github – Published: 2026-06-25 18:30 – Updated: 2026-06-26 09:30
VLAI
Details

A flaw was found in org.keycloak.authorization. An authenticated user with a granted User-Managed Access (UMA) permission ticket for one resource can exploit this by using a specific permission request prefix to bypass per-resource access control. This allows the user to gain unauthorized access to all resources of that type within the same resource server, even if they do not have a ticket for those specific resources. This vulnerability requires the resource server to be configured in PERMISSIVE policy enforcement mode and affects typed resources with ownerManagedAccess enabled, where no explicit policy protects the resource type. The primary consequence is unauthorized information disclosure or modification of resources.

This allows the user to gain unauthorized access to all resources of that type within the same resource server, even if they do not have a ticket for those specific resources. This vulnerability requires the resource server to be configured in PERMISSIVE policy enforcement mode and affects typed resources with ownerManagedAccess enabled, where no explicit policy protects the resource type. The primary consequence is unauthorized information disclosure or modification of resources.",

GHSA-GFVG-4QQV-CQ4M

Vulnerability from github – Published: 2026-09-26 15:31 – Updated: 2026-09-26 15:31
VLAI
Details

Capgo before 12.244.1 contains a cross-tenant integrity vulnerability in the metadata-cleaning worker that trusts image object keys from mutable database rows without validating ownership. An authenticated attacker can place a victim tenant's image key in a row they control, causing the service-role worker to download and re-upload that object with sanitized metadata. Attackers can silently modify metadata in cross-tenant image objects by supplying known victim keys during authorized row updates, bypassing storage access controls through the confused-deputy metadata worker.

Severity

Mitigation
Architecture and Design

For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.

Mitigation
Architecture and Design Implementation

Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.

Mitigation
Architecture and Design

Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
