CVE-2025-4660 is a critical-severity flaw (CVSS 9.8) affecting secureconnector. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A remote code execution vulnerability exists in the Windows agent component of SecureConnector due to improper access controls on a named pipe. The pipe is accessible to the Everyone group and does not restrict remote connections, allowing any network-based attacker to connect without authentication. By interacting with this pipe, an attacker can redirect the agent to communicate with a rogue server that can issue commands via the SecureConnector

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 11.1.02.1019 (Debian / Ubuntu)

apt-cache madison secureconnector sudo apt install secureconnector=<VERSION_BEFORE_11.1.02.1019> sudo apt-mark hold secureconnector

dnf --showduplicates list secureconnector sudo dnf downgrade secureconnector-<VERSION_BEFORE_11.1.02.1019> sudo dnf versionlock add secureconnector

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.
