CVE-2026-23268
HighSummary
W jądrze Linuxa zidentyfikowano podatność, która pozwala nieuprzywilejowanemu lokalnemu użytkownikowi na zarządzanie politykami AppArmor. Użytkownik może załadować, zastąpić lub usunąć profile, wykorzystując atak 'confused deputy', co prowadzi do pełnego zarządzania polityką.
Risk Assessment
Organizacja może być narażona na poważne zagrożenia, takie jak usunięcie ograniczeń bezpieczeństwa, ataki DoS na system lub aplikacje oraz eskalacja uprawnień lokalnych. Potencjalne konsekwencje mogą prowadzić do poważnych naruszeń bezpieczeństwa.
Recommendation
Zaleca się, aby upewnić się, że zadanie zapisujące do interfejsu ma uprawnienia będące podzbiorem zadania, które otworzyło interfejs. Należy również monitorować i ograniczać dostęp do otwartych deskryptorów plików przez nieuprzywilejowane procesy.

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.

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.
- CVE-2026-14494Critical
The Sigma Forms Pro plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.4.5 via the handle_form_submission function. This is due to the plugin dynamically granting the unfiltered_upload capability to all users during form submissions and bypassing MIME type validation when allowed_file_types is not configured. This makes it possible for unauthenticated attackers to execute code on the server. Several default pre-built templates including Job Application, Support Ticket, and Wholesale Application have file upload fields with no file type restrictions configured by design, making this vulnerability immediately exploitable upon installation.
- CVE-2026-3627Critical
IBM Concert versions 1.0.0 through 2.3.1 are vulnerable to SQL injection. A remote attacker could send specially crafted SQL statements, potentially allowing viewing, adding, modifying, or deleting information in the back-end database.
- CVE-2026-19295Critical
IBM Langflow OSS versions 1.0.0 through 1.11.1 allow an authenticated attacker to execute arbitrary operating system commands in the server process by saving a flow with a crafted type field value and triggering a build of a wrapper flow that references it. This allows privilege escalation from 'authenticated flow user' to arbitrary OS-level command execution, bypassing the LANGFLOW_ALLOW_CUSTOM_COMPONENTS=false policy.
- CVE-2026-19286Critical
IBM Langflow OSS versions 1.0.0 through 1.11.1 could allow a remote attacker to execute arbitrary code due to improper enforcement of security restrictions on the A2A public endpoint.
Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: apparmor: fix unprivileged local user can do privileged policy management An unprivileged local user can load, replace, and remove profiles by opening the apparmorfs interfaces, via a confused deputy attack, by passing the opened fd to a privileged process, and getting the privileged process to write to the interface. This does require a privileged target that can be manipulated to do the write for the unprivileged process, but once such access is achieved full policy management is possible and all the possible implications that implies: removing confinement, DoS of system or target applications by denying all execution, by-passing the unprivileged user namespace restriction, to exploiting kernel bugs for a local privilege escalation. The policy management interface can not have its permissions simply changed from 0666 to 0600 because non-root processes need to be able to load policy to different policy namespaces. Instead ensure the task writing the interface has privileges that are a subset of the task that opened the interface. This is already done via policy for confined processes, but unconfined can delegate access to the opened fd, by-passing the usual policy check.
