CVE-2026-15656 is a medium-severity flaw (CVSS 4.3) affecting maximo application suite. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
IBM Maximo Application Suite 9.2, 9.1, and 9.0 does not set the secure attribute on authorization tokens or session cookies. Attackers may be able to get the cookie values by sending a http:// link to a user or by planting this link in a site the user goes to. The cookie will be sent to the insecure link and the attacker can then obtain the cookie value by snooping the traffic.

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.
3. If no update is available yet, DOWNGRADE to a release before 9.0 (Debian / Ubuntu)
apt-cache madison maximo-application-suite
sudo apt install maximo-application-suite=<VERSION_BEFORE_9.0>
sudo apt-mark hold maximo-application-suite
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list maximo-application-suite
sudo dnf downgrade maximo-application-suite-<VERSION_BEFORE_9.0>
sudo dnf versionlock add maximo-application-suite
Downgrade risk
Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.
After downgrade
Restart the service, and keep the package held until a fixed release ships.
