CVE-2026-78699
HighCVSS 7.2Summary
A vulnerability in ash-project ash_postgres allows a user who can drive a tenant rename to a name that collides with an existing tenant's schema to have their tenant record repointed at that other tenant's live schema, gaining access to its data. The rename_tenant/3 function ignores the SQL query result and always returns :ok, leading to the new name being saved and subsequent access to other tenants' data. Affects ash_postgres from 0.25.0 before 2.13.0.
Risk Assessment
Risk of unauthorized access to other tenants' data in applications using ash_postgres, potentially leading to leakage of sensitive information.
Recommendation
Update ash_postgres to version 2.13.0 or later, which includes the fix.

- CVE-2026-15980Critical
The MyHome Core plugin for WordPress up to version 4.4.5 contains an authentication bypass vulnerability. This is due to missing authorization in the send_link() AJAX handler and improper token validation in the activate() function. This allows unauthenticated attackers to generate an activation token for an unconfirmed user account and obtain a valid authentication cookie for that account, including administrators.
- CVE-2026-15369Critical
The Custom User Registration Fields for WooCommerce plugin for WordPress is vulnerable to Privilege Escalation in versions up to and including 2.2.3. This is due to the plugin accepting an attacker-controlled afreg_select_user_role value from the unauthenticated WooCommerce Store API /wc/store/v1/checkout request, persisting it in order meta, and then passing it directly to WP_User::add_role() without validating against the plugin's admin-configured allowed role list. This makes it possible for unauthenticated attackers to elevate their privileges to Administrator by creating an account during checkout with a modified JSON body specifying administrator as the desired role.
- CVE-2026-82460Critical
Cloud Commander before version 19.20.2 contains a directory traversal vulnerability in REST file-operation and markdown endpoints that fails to properly validate path normalization. Attackers can use path traversal sequences to read, write, move, or copy files outside the configured root directory.
- CVE-2026-82456Critical
argocd-mcp 0.8.0 binds its HTTP transport to every network interface and accepts MCP sessions without requiring caller credentials when ARGOCD_API_TOKEN is configured. Attackers who can reach the listener can invoke the full tool surface using the operator's stored token to create applications, request syncs, and modify Argo CD resources.
- CVE-2026-82454Critical
The Omnivore API (packages/api) before the fix in commit abf53d6 contains an authentication bypass in Apple sign-in token verification. The decodeAppleToken function extracted the 'alg' field from the attacker-supplied JWT header and passed it as the sole allowed algorithm to jwt.verify(). Using jsonwebtoken v8 (which does not validate key/algorithm compatibility), an attacker can set alg=HS256 and sign a forged token using Apple's publicly available RSA public key as the HMAC secret, bypassing signature verification and impersonating any Apple-linked account.
- CVE-2026-82452Critical
rust-iot-platform through commit 5df942ab contains an authentication bypass vulnerability where most REST API routes lack authentication guards in their handler signatures. Unauthenticated attackers can create, update, list, retrieve, and delete user accounts by directly accessing unprotected endpoints without providing valid credentials.
- CVE-2026-82448Critical
Shinobi before commit 5a76c74f contains a hardcoded connection key in the child node service that allows unauthenticated attackers to execute arbitrary database queries. Attackers reaching the child node port can present the hardcoded key during WebSocket handshake, then dispatch SQL queries through the onWebSocketDataFromChildNode handler to read and modify user records and camera configuration.
Original NVD description (English source)
Unchecked Return Value vulnerability in ash-project ash_postgres allows a user who can drive a tenant rename to a name that collides with an existing tenant's schema to have their tenant record repointed at that other tenant's live schema, gaining access to its data. AshPostgres.MultiTenancy.rename_tenant/3 issues the ALTER SCHEMA ... RENAME TO ... with the non-raising Ecto.Adapters.SQL.query/2, discards its {:ok, _} | {:error, _} result, and unconditionally returns :ok. PostgreSQL rejects the rename when the target schema already exists (and on insufficient privilege or lock timeout), but that failure never reaches the caller. The calling manage_tenant update action therefore sees success and commits the tenant row with the new name, which is the schema of a different existing tenant, so subsequent reads and writes for that tenant run against the other tenant's data. This issue affects ash_postgres: from 0.25.0 before 2.13.0.
