Critical [CVE-2025-48431 +10] April 2026 Apache Thrift Vulnerabilities in NetApp Products
Multiple NetApp products incorporate Apache Thrift. Apache Thrift versions prior to 0.23.0 are susceptible to vulnerabilities which when successfully exploited could lead to disclosure of sensitive information, addition or modification of data, or Denial of Service (DoS). NetApp reports that one or more additional products remain under investigation; review the canonical advisory for current status. NetApp states there is no workaround available at this time.

Critical [CVE-2025-12686] Buffer copy without checking size of input ('Classic Buffer Overflow') vulnerability in AdminCenter in Synology BeeStation OS before 1.3.2-65648 allows remote attackers to execute arbitrary code via unspecified vectors
Buffer copy without checking size of input ('Classic Buffer Overflow') vulnerability in AdminCenter in Synology BeeStation OS before 1.3.2-65648 allows remote attackers to execute arbitrary code via unspecified vectors. Affected products named by the advisory: BeeStation OS 1.3; BeeStation OS 1.2; BeeStation OS 1.1; BeeStation OS 1.0.
Critical [CVE-2026-9256] NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_rewrite_module module
NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_rewrite_module module. This vulnerability exists when a rewrite directive uses a regex pattern with distinct, overlapping Perl-Compatible Regular Expression (PCRE) captures (for example, ^/((.*))$) and a replacement string that references multiple such captures (for example, $1$2) in a redirect or arguments context. An unauthenticated attacker along with conditions beyond their control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
Critical [CVE-2026-20223] Cisco Secure Workload Unauthorized API Access Vulnerability
A vulnerability in the access validation of internal REST APIs of Cisco Secure Workload could allow an unauthenticated, remote attacker to access site resources with the privileges of the Site Admin role. This vulnerability is due to insufficient validation and authentication when accessing REST API endpoints. An attacker could exploit this vulnerability if they are able to send a crafted API request to an affected endpoint. A successful exploit could allow the attacker to read sensitive information and make configuration changes across tenant boundaries with the privileges of the Site Admin user. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
Critical [CVE-2026-8711] NGINX JavaScript has a vulnerability when the js_fetch_proxy directive is configured with at least one client-controlled NGINX variable (for example, $http_*, $arg_*, $cookie_*) and a location invoking the ngx.fetch operation from NGINX JavaScript
NGINX JavaScript has a vulnerability when the js_fetch_proxy directive is configured with at least one client-controlled NGINX variable (for example, $http_*, $arg_*, $cookie_*) and a location invoking the ngx.fetch() operation from NGINX JavaScript. An unauthenticated attacker can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
Critical [CVE-2026-42945] NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_rewrite_module module
NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_rewrite_module module. This vulnerability exists when the rewrite directive is followed by a rewrite, if, or set directive and an unnamed Perl-Compatible Regular Expression (PCRE) capture (for example, $1, $2) with a replacement string that includes a question mark (?). An unauthenticated attacker along with conditions beyond its control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
Critical [CVE-2026-44277] Improper access control on API endpoints
CVSSv3 Score: 9.1 An Improper Access Control vulnerability [CWE-284] in FortiAuthenticator may allow an unauthenticated attacker to execute unauthorized code or commands via crafted requests. Revised on 2026-05-12 00:00:00
Critical [CVE-2026-26083] Incorrect global authorization
CVSSv3 Score: 9.1 A missing authorization vulnerability [CWE-862] in FortiSandbox, FortiSandbox Cloud and FortiSandbox PaaS WEB UI may allow an unauthenticated attacker to execute unauthorized code or commands via HTTP requests. Revised on 2026-05-12 00:00:00
Critical [CVE-2026-25199] Instances deployed via the Proxmox extension allow unauthorized access to instances belonging to other tenants
Instances deployed via the Proxmox extension allow unauthorized access to instances belonging to other tenants. This issue affects Apache CloudStack: from 4.21.0.0 through 4.22.0.0. The Proxmox extension for CloudStack improperly uses a user-editable instance setting, proxmox_vmid, to associate CloudStack instances with Proxmox virtual machines. Because this value is not restricted or validated against tenant ownership and Proxmox VM IDs are predictable, a non-privileged attacker can modify the setting to reference a VM belonging to another account. This allows unauthorized cross-tenant access and enables full control over the targeted VM, including starting, stopping, and destroying the virtual machine. Users are recommended to upgrade to version 4.22.0.1, which fixes this issue. As a workaround for the existing installations, editing of the proxmox_vmid instance detail by users can be prevented by adding this detail name to the global configuration parameter - user.vm.denied.details.
Critical [CVE-2025-69691] Netgate pfSense CE 2.8.0 allows code execution in the XMLRPC API via pfsense.exec_php
Netgate pfSense CE 2.8.0 allows code execution in the XMLRPC API via pfsense.exec_php. NOTE: the Supplier disputes this because the API call is only available to admins and they are intentionally allowed to execute PHP code.
Critical [CVE-2025-69690] Netgate pfSense CE 2.7.2 allows code execution by using the module installer with a backup file with a serialized PHP object containing the post_reboot_commands property
Netgate pfSense CE 2.7.2 allows code execution by using the module installer with a backup file with a serialized PHP object containing the post_reboot_commands property. NOTE: the Supplier disputes this because this installer is only available to admins and they are intentionally allowed to execute PHP code.
Critical [CVE-2026-22984] Linux Kernel Vulnerability in NetApp Products
Multiple NetApp products incorporate Linux kernel. Linux kernel versions through 5.15.197, 5.16-rc1 through 6.1.160, 6.13-rc1 through 6.18.5, 6.19-rc1 through 6.19-rc4, 6.2-rc1 through 6.6.120 and 6.7-rc1 through 6.12.65 are susceptible to a vulnerability which when successfully exploited could lead to disclosure of sensitive information, addition or modification of data or Denial of Service (DoS). NetApp reports that one or more additional products remain under investigation; review the canonical advisory for current status. NetApp states there is no workaround available at this time.
