CVE-2026-40977
Description
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 integrity issues or a denial of service (DoS) by rendering critical system files unusable.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
