  1. CVE-2026-48027 9.8 Critique Exploitée Rançongiciel

    nrwl nx-console · Nx nx console

    Nx Console is the user interface for Nx & Lerna. On 19 May 2026, a malicious version of Nx Console, 18.95.0, was published at 12:30 PM UTC and removed soon after at 12:48 PM UTC, leaving it available for ~18 minutes in Visual Studio Marketplace. For OpenVSX, the problem was detected later, and the compromised version was available from 12:33 UTC to 13:09 UTC (~36 minutes). Version 18.100.0 of Nx Console is not compromised and users may remediate by upgrading to that version.

  2. CVE-2026-5260 8.2 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 10.0 Extended Update Support · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support

    A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS#11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure.

  3. CVE-2026-48172 9.8 Critique Exploitée

    LiteSpeed Technologies cPanel Plugin · LiteSpeed Technologies WHM Plugin · Litespeedtech litespeed cpanel plugin · Litespeedtech litespeed whm plugin

    LiteSpeed User-End cPanel Plugin before 2.4.5 allows privilege escalation (possibly to root), as exploited in the wild in May 2026. Detection is best done via a command line of grep -rE "cpanel_jsonapi_func=redisAble" /var/cpanel/logs /usr/local/cpanel/logs/ 2>/dev/null in Bash. If you get no output, you have not been hit with exploitation of the vulnerability. If there is output, we recommend you examine the IP addresses in the list, determine if they are valid IP addresses, and if not, block them. To determine damage done, examine the system logs for use by the detected IP addresses. The issue is related to mishandling of Redis enable/disable features. The recommended minimum version is 2.4.7.

  4. CVE-2026-41091 7.8 Élevée Exploitée

    Microsoft Malware Protection Engine

    Improper link resolution before file access ('link following') in Microsoft Defender allows an authorized attacker to elevate privileges locally.

  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.

  6. CVE-2026-42208 9.8 Critique Exploitée

    BerriAI litellm · Red Hat Lightspeed Core · Red Hat Ansible Automation Platform 2 · Red Hat OpenShift AI (RHOAI)

    LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. From version 1.81.16 to before version 1.83.7, a database query used during proxy API key checks mixed the caller-supplied key value into the query text instead of passing it as a separate parameter. An unauthenticated attacker could send a specially crafted Authorization header to any LLM API route (for example POST /chat/completions) and reach this query through the proxy's error-handling path. An attacker could read data from the proxy's database and may be able to modify it, leading to unauthorised access to the proxy and the credentials it manages. This issue has been patched in version 1.83.7.

  7. CVE-2026-0300 9.8 Critique Exploitée

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

    A buffer overflow vulnerability in the User-ID™ Authentication Portal (aka Captive Portal) service of Palo Alto Networks PAN-OS software allows an unauthenticated attacker to execute arbitrary code with root privileges on the PA-Series and VM-Series firewalls by sending specially crafted packets. The risk of this issue is greatly reduced if you secure access to the User-ID™ Authentication Portal per the best practice guidelines https://knowledgebase.paloaltonetworks.com/KCSArticleDetail by restricting access to only trusted internal IP addresses. Prisma Access, Cloud NGFW and Panorama appliances are not impacted by this vulnerability.
