CVE-2026-17598 is a medium-severity flaw (CVSS 4.9) affecting nexus repository manager. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Sonatype Nexus Repository 3 did not properly filter internal configuration keys from user-supplied task properties when creating or updating a scheduled task through the administrative UI. An account holding permission to create at least one scheduled task type could supply a crafted property value that caused the system to overwrite the configuration of an unrelated, existing task instead of creating a new one.

apt-cache madison nexus-repository-manager
sudo apt install nexus-repository-manager=<VERSION_BEFORE_3.91.0>
sudo apt-mark hold nexus-repository-manager

dnf --showduplicates list nexus-repository-manager
sudo dnf downgrade nexus-repository-manager-<VERSION_BEFORE_3.91.0>
sudo dnf versionlock add nexus-repository-manager
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.
