CVE-2026-41696 is a medium-severity flaw (CVSS 5.9) affecting spring data mongodb. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Spring Data MongoDB repository query methods annotated with @Query that use regex parameter binding perform insufficient validation of the bound parameter. An attacker can supply a crafted string to break out of the intended regular expression quoting. Affected versions: Spring Data MongoDB 5.0.0 through 5.0.5; 4.5.0 through 4.5.11; 4.4.0 through 4.4.14; 4.3.0 through 4.3.16; 4.2.0 through 4.2.15; 4.1.0 through 4.1.14; 4.0.0 through 4.0.15; 3.4.

vmware spring data mongodb UPGRADE

Affected: >= 3.4.0 and < 3.4.20 · >= 4.0.0 and <= 4.0.15 · >= 4.1.0 and <= 4.1.14 · >= 4.2.0 and <= 4.2.15 · >= 4.3.0 and < 4.3.17 · >= 4.4.0 and < 4.4.15 · >= 4.5.0 and < 4.5.11.1 · >= 5.0.0 and < 5.0.5.1

Fixed in: 3.4.20, 4.3.17, 4.4.15, 4.5.11.1, 5.0.5.1

Safe to downgrade to: a release before 3.4.0

1. Check installed version

apt-cache policy spring-data-mongodb || rpm -q spring-data-mongodb || spring-data-mongodb --version

2. UPGRADE to 3.4.20 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade spring-data-mongodb

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade spring-data-mongodb

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 3.4.0 (Debian / Ubuntu)

apt-cache madison spring-data-mongodb sudo apt install spring-data-mongodb=<VERSION_BEFORE_3.4.0> sudo apt-mark hold spring-data-mongodb

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list spring-data-mongodb sudo dnf downgrade spring-data-mongodb-<VERSION_BEFORE_3.4.0> sudo dnf versionlock add spring-data-mongodb

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.
