Routine

MEDIUM 4.8REMOTEUPGRADE

CVE-2026-41697 is a medium-severity flaw (CVSS 4.8) affecting spring data relational. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Spring Data Relational does not properly escape binding values of externally-controlled input when using StringMatcher (STARTING, ENDING, or CONTAINING) in Query By Example (QBE). An attacker can supply wildcard characters to perform boolean-based blind data inference. Affected versions: Spring Data Relational/JDBC/R2DBC 4.0.0 through 4.0.5; 3.5.0 through 3.5.11; 3.4.0 through 3.4.14; 3.3.0 through 3.3.16; 3.2.0 through 3.2.15; 3.1.0 through 3.1

Why this priority

Remotely exploitable, no login, no user action

A fixed release or distro patch exists.

broadcom spring data relational UPGRADE

Affected: < 2.4.20 · >= 3.0.0 and < 3.3.17 · >= 3.4.0 and < 3.4.15 · >= 3.5.0 and < 3.5.11.1 · >= 4.0.0 and < 4.0.5.1

Fixed in: 2.4.20, 3.3.17, 3.4.15, 3.5.11.1, 4.0.5.1

Safe to downgrade to: a release before 3.0.0

1. Check installed version

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

2. UPGRADE to 2.4.20 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade spring-data-relational

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 3.0.0 (Debian / Ubuntu)

apt-cache madison spring-data-relational sudo apt install spring-data-relational=<VERSION_BEFORE_3.0.0> sudo apt-mark hold spring-data-relational

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

dnf --showduplicates list spring-data-relational sudo dnf downgrade spring-data-relational-<VERSION_BEFORE_3.0.0> sudo dnf versionlock add spring-data-relational

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.
