Technical details
A path traversal vulnerability exists in the FileHelper.unzip function in common/src/main/java/com/flowci/common/helper/FileHelper.java. The function fails to properly validate ZIP archive contents before extraction, allowing crafted archives with directory traversal sequences (e.g., "../") to write files outside the target directory. Remote attackers can exploit this via specially crafted job report ZIP files, though the attack requires high complexity to execute.
