CVE-2026-22741

CVE-2026-22741 – cache poisoning in static resources (Spring MVC/WebFlux) . When an app uses Spring MVC/WebFlux with resource chain caching enabled and encoded resource resolution, and the resource cache is empty, an attacker can poison the cache by sending crafted requests with incorrect encodin...

Authorization Bypass

spring-security-config is vulnerable to Authorization Bypass. The vulnerability is due to incorrect handling of the servlet-path attribute in , where the servlet path is not included when computing the path matcher, causing defined authorization rules to be skipped and allowing unauthorized acces...

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...

CVE-2026-22740 Spring Framework DoS with Multipart Temp Files in WebFlux

A WebFlux server application that processes multipart requests creates temp files for parts larger than 10 K. Under some circumstances, temp files may remain not deleted after the request is fully processed. This allows an attacker to consume available disk space. Older, unsupported versions are...

CVE-2026-22740

The CVE-2026-22740 issue affects Spring Framework WebFlux multipart request handling. The root cause is cleanup of temporary files created for parts larger than 10 KB, which in some cases are not deleted after the request completes, enabling an attacker to exhaust disk space (Denial of Service). ...

CVE-2026-22740 Spring Framework DoS with Multipart Temp Files in WebFlux

A WebFlux server application that processes multipart requests creates temp files for parts larger than 10 K. Under some circumstances, temp files may remain not deleted after the request is fully processed. This allows an attacker to consume available disk space. Older, unsupported versions are...

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...

Denial Of Service (DoS)

Spring Core is vulnerable to Denial of Service DoS. The vulnerability is due to inefficient handling of static resource resolution on Windows file systems, where specially crafted requests can take excessive time to process and hold HTTP connections open, leading to resource exhaustion and servic...

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...

Denial Of Service (DoS)

Spring Web is vulnerable to Denial of Service DoS. The vulnerability is due to improper cleanup of temporary files created during multipart request processing, where files for large parts may not be deleted after request completion, allowing attackers to exhaust disk space...

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...
