What happenedAttackers chained three flaws in Ivanti Connect Secure to get full root-level control without logging in, and CISA added two of them to its list of exploited bugs.
Who is affectedOrganizations running Ivanti Connect Secure, a remote access product, including US federal agencies that must patch by set deadlines.
What to do
  1. 1Check whether your company uses Ivanti Connect Secure and ask your IT team or provider.
  2. 2Install the latest Ivanti release that fixes all three chained flaws.
  3. 3Change administrator passwords and review any stored BitLocker recovery keys if you suspect exposure.
  4. 4Ask your IT team to check logs for unusual logins or credential theft.

The U.S. cyber agency CISA has confirmed that two more flaws in Ivanti Connect Secure are being used in real attacks. Connect Secure is software that lets employees reach company systems from home. Security firm Volexity says attackers chained three flaws together to take full control of the device without ever logging in.

What happened

CISA added the two flaws to its Known Exploited Vulnerabilities list on Friday. That list tracks bugs that criminals or spies are already using. A third flaw in the same chain, CVE-2026-104935, was added on October 13, 2026.

Volexity first described the chain earlier this month. It joins three steps: getting past the login, running the attacker's own commands, and raising access to the highest level, known as root. The group behind it is called UTA0576 and had not been documented before.

What the attackers wanted

Many attacks like this install hidden backdoors or malware. This group did something different. Volexity saw it pull out credentials, collect limited information about the company's Active Directory (the system that manages staff accounts), and look around the compromised device. It also searched for administrator passwords and BitLocker recovery keys. Those keys can unlock encrypted company laptops.

The fix and the timing

Ivanti has released patches for CVE-2026-111357 and CVE-2026-118527. The company says its latest release covers all of the flaws that were chained and exploited. It also says it had already fixed part of one flaw in its July release, 25.1.3.0, and was copying that fix to other supported versions when attacks began.

Ivanti chose to ship the fix for the main entry point first, rather than wait for the last piece. That explains why the fixes arrived in stages.

Who it affects

Any organization running Ivanti Connect Secure is in scope. Federal civilian agencies must patch CVE-2026-111357 by November 2, 2026, and CVE-2026-118527 by November 13, 2026. Businesses are not bound by those dates, but the attacks are already happening. Companies that do not use this product are not affected by these particular flaws.

What to do

The alert box above lists the steps. The key point is to confirm with your IT team or provider whether Connect Secure is in use, and to get the latest release installed.

What is not known yet

The material does not say how many organizations were hit or who the targets were. It also does not say whether other groups are using the same chain. Because the attackers went after passwords and recovery keys, a patched device may still need follow-up checks if it was exposed before the update.

The takeaway

If your business uses Ivanti Connect Secure, install the latest release now and have IT check for stolen credentials.
