Timeline

vmware spring security UPGRADE
Affected: >= 6.5.0 and < 6.5.12 · >= 7.0.0 and < 7.0.6.1 · >= 7.1.0 and < 7.1.0.1
Fixed in: 6.5.12, 7.0.6.1, 7.1.0.1
Safe to downgrade to: a release before 6.5.0
1. Check installed version
apt-cache policy spring-security || rpm -q spring-security || spring-security --version
2. UPGRADE to 6.5.12 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade spring-security
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade spring-security
Note
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 6.5.0 (Debian / Ubuntu)
apt-cache madison spring-security sudo apt install spring-security=<VERSION_BEFORE_6.5.0> sudo apt-mark hold spring-security
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list spring-security sudo dnf downgrade spring-security-<VERSION_BEFORE_6.5.0> sudo dnf versionlock add spring-security
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.
