  1. CVE-2026-42338 6.1 Moyenne

    beaugunderson ip-address · Red Hat AMQ Broker 7.13.6 · Red Hat AMQ Broker 7.14.1 · Red Hat Enterprise Linux 10

    ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Prior to 10.1.1, Address6.group() and Address6.link() do not HTML-escape attacker-controlled content before embedding it in the HTML strings they return, and AddressError.parseMessage (emitted by the Address6 constructor for invalid input) can contain unescaped attacker-controlled content in one branch. An application that (1) passes untrusted input to Address6 and (2) renders the output of these methods, or the thrown error's parseMessage, as HTML (e.g. via innerHTML) is vulnerable to cross-site scripting. This vulnerability is fixed in 10.1.1.

  2. CVE-2026-42899 7.5 Élevée

    Microsoft .NET 10.0 · Microsoft .NET 8.0 · Microsoft .NET 9.0 · Red Hat Enterprise Linux 10

    Loop with unreachable exit condition ('infinite loop') in ASP.NET Core allows an unauthorized attacker to deny service over a network.

  3. CVE-2026-42177 5.3 Moyenne

    siemens linux-entra-sso

    linux-entra-sso is a browser plugin for Linux to SSO on Microsoft Entra ID. Prior to 1.8.1, platform/chrome/js/platform-chrome.js:69-88 registers a single declarativeNetRequest rule whose urlFilter is Platform.SSO_URL + "/*", i.e. "https://login.microsoftonline.com/*". Chrome's urlFilter without a | or || anchor is substring-matched against the full request URL. The same applied rule action is modifyHeaders that attaches the Entra ID Primary Refresh Token cookie. The Firefox adapter in platform/firefox/js/platform-firefox.js:53 performs a belt-and-braces startsWith(Platform.SSO_URL) check before injecting the header; the Chrome adapter does not. When the extension holds broad host permissions through the optional_host_permissions: ["https://*/*"] declared in platform/chrome/manifest.json:34, a main-frame navigation to a URL whose path embeds https://login.microsoftonline.com/ causes Chrome to attach the PRT cookie to the request to the attacker-controlled host. This vulnerability is fixed in 1.8.1.

  4. CVE-2026-35433 7.3 Élevée

    Microsoft .NET 10.0 · Microsoft .NET 8.0 · Microsoft .NET 9.0 · Microsoft .NET Framework 3.5

    Improper input validation in .NET allows an unauthorized attacker to elevate privileges locally.

  5. CVE-2026-32177 7.3 Élevée

    Microsoft .NET 10.0 · Microsoft .NET 8.0 · Microsoft .NET 9.0 · Microsoft .NET Framework 3.5

    Heap-based buffer overflow in .NET allows an unauthorized attacker to elevate privileges locally.

  6. CVE-2025-27723 6.8 Moyenne

    Intel(R) Ethernet 800 series

    Use after free for some Linux kernel driver for the Intel(R) Ethernet 800 series before version 2.3.14 within Ring 0: Kernel may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (high) impacts.

  12. CVE-2026-42006 4.3 Moyenne

    Open-Xchange GmbH OX Dovecot Pro · Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 10.0 Extended Update Support · Red Hat Enterprise Linux 7 Extended Lifecycle Support

    An attacker can cause uncontrolled memory usage with excessive bracing over IMAP. The fix in CVE-2026-27857 was incomplete, only blocking one way of doing this, so there was still another way left open. In particular, the fix was for closing braces, but you could still use open braces to bypass the limit. Using excessive bracing, attacker can cause memory usage up to configured memory limit. Install fixed version, or configure vsz_limit for imap process to low value. No publicly available exploits are known.

  13. CVE-2026-27851 9.1 Critique

    Open-Xchange GmbH OX Dovecot Pro · Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 8

    When safe filter is used with variable expansion, all following pipelines on the same string are incorrectly interpreted as safe too, enabling unsafe data to be unescaped. This can enable SQL / LDAP injection attacks when used in authentication. Avoid using safe filter until on fixed version. No publicly available exploits are known.

  14. CVE-2026-45391 7.8 Élevée

    Cribl Edge

    A command injection vulnerability in Cribl Edge for Linux versions 3.2.0 through 4.17.0 allows a local unprivileged user to execute arbitrary commands in the context of the Cribl Edge service account.
