CVE-2021-32769

24
FAUCET Score

CVE-2021-32769 is a path traversal vulnerability affecting Micronaut, a JVM-based Java framework, in versions prior to 2.5.9. This flaw allows an unauthenticated attacker to access arbitrary files on the filesystem by manipulating URLs with "../" sequences, due to insufficient restriction of file access to configured paths. Rated with a CVSS score of 7.5 (HIGH), it presents a significant risk of information disclosure (C:H) with low attack complexity and no user interaction required. While no active exploitation, public exploit code, or significant community discussion has been observed, organizations using affected Micronaut versions should upgrade to 2.5.9 or implement the recommended workarounds to mitigate this risk.
