CVE-2026-71215
HighCVSS 7.5Exploitation Probability (EPSS)
Low risk30th percentile - higher than 30% of all known CVEs
Summary
In art-template's sub-template resolution logic (src/compile/adapter/resolve-filename.js), used by both the include and extend template directives, the target file path is resolved via path.resolve(root, filename) with no check afterward that the result remains inside root.
Risk Assessment
An attacker could exploit this to read or write files outside the root directory, potentially leading to disclosure of sensitive data or code execution.
Recommendation
Update art-template to a patched version or add path validation to prevent access outside the root directory.

- 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.
- 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-2026-77012Critical
The 爱采集数据采集和发布插件 WordPress plugin through 1.0.0 does not require a per-install secret for one of its unauthenticated endpoints, relying on a hardcoded default, and does not validate the URLs or destination paths it is given. This allows unauthenticated attackers to read arbitrary files from the server, force it to issue arbitrary requests and retrieve the responses, and write attacker-supplied content outside the uploads directory.
- CVE-2026-16947Critical
The Total processing card payments for WooCommerce WordPress plugin through version 7.3 does not validate a user-supplied path before using it to build a server-side verification request, and does not verify the authenticity of the response. This allows unauthenticated attackers to redirect that request to an arbitrary host (disclosing the merchant's payment-gateway credentials) and to forge a success response that marks arbitrary WooCommerce orders as paid.
