TODAY

VPN gateways and load balancers under active attack — patch now.

THE THREE

  1. #1 · CVE-2026-34486

    Apache

    KEV

    What: If your org runs Apache Tomcat (versions 11.0.20, 10.1.53, or 9.0.116), session data that should be encrypted is exposed in transit — attackers can intercept sensitive application data or hijack sessions. With 83% exploit probability and active exploitation confirmed, this is a patch-today situation for any Java web app team.

    Why it moved: Actively exploited · Everyone runs this · 83% exploit odds

    Who is exploiting: Actively-exploited (CISA KEV)

    Action · Upgrade Apache Tomcat to 11.0.21, 10.1.54, or 9.0.117 immediately.

  2. #2 · CVE-2026-10520

    Ivanti

    KEV

    What: Ivanti Sentry has a perfect CVSS 10.0 OS command injection flaw — an unauthenticated attacker on the internet can get root-level control of your mobile device management gateway, potentially exposing every managed device and credential flowing through it. This has been actively exploited for over two months.

    Why it moved: Actively exploited · Widely deployed · Critical severity · 100% exploit odds

    Who is exploiting: Actively-exploited (CISA KEV)

    Action · Isolate Ivanti Sentry from public internet and apply vendor patch immediately.

  3. #3 · CVE-2026-0257

    Palo Alto

    KEV

    What: Attackers can bypass authentication on Palo Alto PAN-OS and establish unauthorized VPN connections — effectively walking through your perimeter firewall as a trusted user. With 94% exploit odds and active exploitation, any internet-facing PAN-OS device is a live target.

    Why it moved: Actively exploited · Widely deployed · Critical severity · 94% exploit odds

    Who is exploiting: Actively-exploited (CISA KEV)

    Action · Apply Palo Alto's PAN-OS patch and audit VPN connection logs for anomalies now.
