AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in OpenClaw versions before 2026.3.2 and involves a race condition during ZIP file extraction. Specifically, local attackers can exploit a timing gap between path validation and file write operations caused by parent-directory symbolic link (symlink) rebinding. By manipulating these symlinks between the validation and the actual file write, attackers can cause files to be written outside the intended extraction directory.
How can this vulnerability impact me? :
The vulnerability allows local attackers to write files outside the designated extraction directory, potentially overwriting or creating files in unintended locations. This can lead to unauthorized modification of system files or application data, which may compromise system integrity, cause data corruption, or enable further attacks.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
