CVE-2025-70952Public exploitNetwork attack vector

Arbitrary file write via prefix-matched extraction paths

Published Mar 25, 2026 · Updated Mar 25, 2026

Path traversal in pf4j before 3.14.1 allows remote attackers to write files outside the extraction directory via a crafted ZIP archive. Unzip.extract() joins each entry name to the destination and accepts a canonical path when its string merely shares the destination prefix, so a ../ entry targeting a similarly named sibling directory passes validation. The application must pass an attacker-controlled archive to this library routine; resulting writes carry the application's filesystem permissions.
