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...

Linux Distros Unpatched Vulnerability : CVE-2026-40970

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - When configured to use an SSL bundle, Spring Boot's Elasticsearch auto-configuration does not perform hostname verification when connecting to the Elasticsearch...

CVE-2026-40970

A flaw was found in Spring Boot. When configured to use an SSL Secure Sockets Layer bundle, the Elasticsearch auto-configuration component does not perform hostname verification when establishing a connection to the Elasticsearch server. An attacker on an adjacent network could exploit this by...

GHSA-8V8J-3HXP-93WR Spring Boot's default security filter chain has no authorization rule with Actuator but without Health

In certain circumstances, Spring Boot's default web security is ineffective allowing unauthorized access to all endpoints. For an application to be vulnerable, it must: be a servlet-based web application; have no Spring Security configuration of its own and rely on the default web security filter...
