CVE-2026-41729: Spring Data REST is vulnerable to SpEL expression injection through map-typed properties when processing JSON

Routine

HIGH 8.1UPGRADE

CVE-2026-41729 is a high-severity flaw (CVSS 8.1) affecting spring data rest. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Spring Data REST is vulnerable to SpEL expression injection through map-typed properties when processing JSON Patch (application/json-patch+json) requests. When a persistent entity exposes a Map-typed property, the JSON Pointer path segment used as the map key is embedded directly into a SpEL expression without sanitization or validation. Affected versions: Spring Data REST 3.7.0 through 3.7.19; 4.3.0 through 4.3.16; 4.4.0 through 4.4.14; 4.5.0

vmware spring data rest UPGRADE

Affected: >= 3.7.0 and < 3.7.20 · >= 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: 3.7.20, 4.3.17, 4.4.15, 4.5.11.1, 5.0.5.1

Safe to downgrade to: a release before 3.7.0

1. Check installed version

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

2. UPGRADE to 3.7.20 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade spring-data-rest

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 3.7.0 (Debian / Ubuntu)

apt-cache madison spring-data-rest sudo apt install spring-data-rest=<VERSION_BEFORE_3.7.0> sudo apt-mark hold spring-data-rest

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

dnf --showduplicates list spring-data-rest sudo dnf downgrade spring-data-rest-<VERSION_BEFORE_3.7.0> sudo dnf versionlock add spring-data-rest

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.
