Hi Spring fans! In this installment I'm thrilled to have had the opportunity to sit down and talk to Daniel Garnier-Moiroux and talk about "Testing Spring Boot Applications," from Manning! testing springboot java kotlin springframework...

This Week in Spring - May 5th, 2026

Hi, Spring fans! Welcome to another installment of This Week in Spring! It's May 5th, 2026, and I'm in Mainz, Germany, for the legendary JAX conference! It's been infinitely far too long since I've been at this amazing show, and I'm oh-so happy to be back here! Tonight, after my two talks here, I...

CVE-2026-40974

A flaw was found in Spring Boot's Cassandra auto-configuration. This vulnerability allows an adjacent attacker to bypass hostname verification during SSL Secure Sockets Layer connection establishment to Cassandra. This could enable a man-in-the-middle attack, potentially leading to unauthorized...

CVE-2026-40971

A flaw was found in Spring Boot. When configured to use an SSL Secure Sockets Layer bundle, Spring Boot's RabbitMQ auto-configuration does not perform hostname verification when connecting to the RabbitMQ broker. This vulnerability could allow an attacker on the same network to intercept or alter...

Arbitrary File Overwrite

org.springframework.boot, spring-boot is vulnerable to arbitrary file overwrite. The vulnerability is due to insecure handling of the PID file via ApplicationPidFileWriter, which allows a local attacker with write access to the PID file location to exploit symlink behavior and overwrite or corrup...

Improper Hostname Verification

Spring Boot is vulnerable to improper hostname verification. The vulnerability is due to missing hostname verification in SSL bundle configuration, which allows an attacker to perform man-in-the-middle attacks by impersonating the RabbitMQ broker...

Default Security Bypass

Spring Boot is vulnerable to Default Security Bypass. The vulnerability is due to Spring Boot's default web security being ineffective, where an application with no Spring Security configuration and relying on the default web security filter chain can allow unauthorized access to all endpoints, a...

Improper Control Of Temporary Directory Access

org.springframework.boot, spring-boot is vulnerable to improper control of temporary directory access. The vulnerability is due to inadequate ownership verification of the ApplicationTemp directory when persistent sessions are enabled, which allows a local attacker to gain control of the director...

Improper SSL Hostname Verification

org.springframework.boot, spring-boot-elasticsearch is vulnerable to improper SSL hostname verification. The vulnerability is due to missing hostname verification in SSL bundle configuration, which allows an attacker to perform man-in-the-middle attacks by connecting to a malicious Elasticsearch...

Weak Random Value Generation For Secrets (weak PRNG)

Spring Boot is vulnerable to the use of a weak pseudo-random number generator PRNG. The vulnerability is due to the use of predictable random value sources e.g., $random.value, $random.int, $random.long, which allows an attacker to guess or brute-force generated secrets and compromise application...

CVE-2026-40977

A flaw was found in Spring Boot when an application is configured to use ApplicationPidFileWriter. A local attacker with write access to the PID file's location can exploit this vulnerability to corrupt one arbitrary file on the host each time the application is started. This can lead to data...

Timing Attack

org.springframework.boot, spring-boot-devtools is vulnerable to a timing attack. The vulnerability is due to insecure comparison of the DevTools remote secret, which allows an attacker on the same network to exploit timing differences to guess the secret and potentially achieve remote code...
