5 CVE

  1. CVE-2026-8398 9.8 Critique Exploitée

    AVB Disc Soft DAEMON Tools Lite · Disc-soft daemon tools

    A supply chain attack compromised the official installation packages of DAEMON Tools Lite (Windows versions 12.5.0.2421 through 12.5.0.2434), distributed from the legitimate website daemon-tools.cc between approximately April 8, 2026, and May 5, 2026. Attackers gained unauthorized access to the vendor's (AVB Disc Soft) build or distribution infrastructure and trojanized three binaries: DTHelper.exe, DiscSoftBusServiceLite.exe, and DTShellHlp.exe. These files were digitally signed with the legitimate AVB Disc Soft code-signing certificate, allowing the malicious installers to appear trustworthy and bypass signature-based detection.

  2. CVE-2026-42897 6.1 Moyenne Exploitée

    Microsoft Exchange Server 2016 Cumulative Update 23 · Microsoft Exchange Server 2019 Cumulative Update 14 · Microsoft Exchange Server 2019 Cumulative Update 15 · Microsoft Exchange Server Subscription Edition RTM

    Improper neutralization of input during web page generation ('cross-site scripting') in Microsoft Exchange Server allows an unauthorized attacker to perform spoofing over a network.

  3. CVE-2026-20182 10.0 Critique Exploitée

    Cisco Catalyst SD-WAN Controller · Cisco Catalyst SD-WAN Manager · Cisco sd-wan vbond orchestrator · Cisco sd-wan vsmart controller

    May 2026: This security advisory provides the details and fix information for a vulnerability that was discovered and fixed after the was disclosed in February 2026. This new advisory is for a new vulnerability in the control connection handshaking. The section of this advisory includes Show Control Connections guidance to help with system checks.  A vulnerability in the peering authentication in Cisco Catalyst SD-WAN Controller, formerly SD-WAN vSmart, Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, and Cisco Catalyst SD-WAN Validator, formerly SD-WAN vBond, could allow an unauthenticated, remote attacker to bypass authentication and obtain administrative privileges on an affected system. This vulnerability exists because the peering authentication mechanism in an affected system is not working properly. An attacker could exploit this vulnerability by sending crafted requests to the affected system. A successful exploit could allow the attacker to log in to an affected Cisco Catalyst SD-WAN Controller as an internal, high-privileged, non-root user account. Using this account, the attacker could access NETCONF, which would then allow the attacker to manipulate network configuration for the SD-WAN fabric.

  4. CVE-2026-0257 9.1 Critique Exploitée Rançongiciel

    Palo Alto Networks Cloud NGFW · Palo Alto Networks PAN-OS · Palo Alto Networks Prisma Access · Siemens RUGGEDCOM APE1808

    Authentication bypass vulnerabilities in the GlobalProtect portal and gateway of Palo Alto Networks PAN-OS® software allows the attacker to bypass security restrictions and establish an unauthorized VPN connection. Panorama and Cloud NGFW are not impacted by these issues.

  5. CVE-2026-45321 9.6 Critique Exploitée Rançongiciel

    @tanstack arktype-adapter · @tanstack eslint-plugin-router · @tanstack eslint-plugin-start · @tanstack history

    On 2026-05-11, between approximately 19:20 and 19:26 UTC, 84 malicious versions across 42 @tanstack/* packages were published to the npm registry. The publishes were authenticated via the legitimate GitHub Actions OIDC trusted-publisher binding for TanStack/router, but the publish workflow itself was not modified. The attacker chained three known vulnerability classes — a pull_request_target "Pwn Request" misconfiguration, GitHub Actions cache poisoning across the fork↔base trust boundary, and runtime memory extraction of the OIDC token from the Actions runner process — to publish credential-stealing malware under a trusted identity. Each affected package received exactly two malicious versions, published a few minutes apart.
