Vulnerability intelligence

CVE-2026-88771 is identified as an improper input validation vulnerability affecting Citrix NetScaler ADC and NetScaler Gateway products. This flaw enables an unauthenticated attacker to execute arbitrary commands on affected systems. The vulnerability impacts all deployments of NetScaler ADC and NetScaler Gateway, and no specific additional features are required for it to be exploitable. Citrix confirmed that this vulnerability, alongside CVE-2026-88772, has been actively exploited in the wild on unmitigated NetScaler deployments. The company released security updates to address these issues, which were attacked before a public fix was available. NetScaler ADC and NetScaler Gateway appliances are commonly deployed at the edge of enterprise networks, handling functions such as VPN, remote access, load balancing, and user authentication.

CVE-2026-88772 is a memory overflow vulnerability impacting Citrix NetScaler ADC and NetScaler Gateway appliances. This flaw can result in remote code execution (RCE) or a denial-of-service (DoS) condition. The vulnerability specifically affects appliances where Datagram Transport Layer Security (DTLS) is enabled. DTLS is typically enabled by default for VPN virtual servers, meaning NetScaler Gateway deployments are susceptible unless DTLS has been explicitly disabled. Citrix has confirmed that this vulnerability, alongside CVE-2026-88771, has been actively exploited in unmitigated NetScaler deployments.

CVE-2026-14281 is a privilege escalation vulnerability found in the "Automation Web Platform – Notifications and OTP for WooCommerce, Advanced Country Code" WordPress plugin, affecting all versions up to and including 4.8.6. The flaw stems from missing permission enforcement on the publicly accessible REST route `POST /wp-json/wawp/v1/signup/<op>`. This allows unauthenticated attackers to manipulate user metadata by directly passing the `wawp_custom_fields` parameter to WordPress's `update_user_meta()` function without proper validation or a key allowlist. This vulnerability enables an unauthenticated attacker to register a new user account with administrator privileges, thereby gaining full administrative control over the affected WordPress site. Additionally, a related flaw allows for the bypass of the plugin's One-Time Password (OTP) verification step during signup. This occurs because the OTP session token is returned in plaintext, and the `handle_magic_link_request()` function marks the token as verified without actually checking the OTP code value, making the OTP step trivially bypassable.

An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in iOS 26.7.1 and iPadOS 26.7.1, macOS Sequoia 15.8.1, macOS Tahoe 26.7.1. Processing a maliciously crafted file may lead to arbitrary code execution. Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 27.
