Spring Boot: Exposure of Resource to Wrong Sphere
CVE-2022-27772 is a high-severity exposure of resource to wrong sphere vulnerability in Spring Boot from VMware, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 2.2.11 as the first without the flaw, so updating Spring Boot to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.6% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
