Keras versions prior to 3.14.0 are vulnerable to a path traversal issue in the archive extraction utilities located in `keras/src/utils/file_utils.py`. The functions `filter_safe_tarinfos()` and `filter_safe_zipinfos()` validate archive member paths against the process current working directory (CWD) instead of the actual extraction destination. When the process runs with CWD set to `/`, which is common in Docker containers, CI/CD runners, and Jupyter environments, the validation boundary becomes the filesystem root, allowing traversal paths to bypass the security check. Additionally, the zip filter contains a bug that causes an `AttributeError` when a blocked entry is encountered, leading to incomplete extraction. Furthermore, Python 3.11 installations lack the `filter="data"` safety net, leaving them entirely reliant on the flawed CWD-based filter. Exploitation of this vulnerability can result in arbitrary file writes outside the intended extraction directory, enabling attackers to o

This CVE exploits attack patterns that Casky's 331matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.
Keras versions before 3.14.0 contain a critical path traversal vulnerability in their archive extraction utilities that fails to properly validate file paths during extraction. The vulnerable functions `filter_safe_tarinfos()` and `filter_safe_zipinfos()` validate paths against the process current working directory rather than the actual extraction destination, creating a security gap that widens significantly when processes run with CWD set to `/`—a common configuration in containerized environments, CI/CD pipelines, and Jupyter notebooks. This affects any application using vulnerable Keras versions to extract untrusted archives, allowing attackers to write files outside intended directories and potentially achieve remote code execution or system compromise.
Casky's 331 mapped security skills enable practitioners to detect the attack patterns underlying this vulnerability across MITRE ATT&CK's Initial Access (TA0001) and Discovery (TA0007) phases. Using Claude AI's extended reasoning capabilities, practitioners can identify suspicious archive extraction activities by correlating indicators such as: malicious tar/zip files with crafted path sequences (../ patterns), extraction operations originating from unexpected processes or sources, file writes to system directories outside the intended extraction scope, and container/CI environment context where CWD=/ amplifies risk. Findings would surface attempted privilege escalation, unauthorized file modifications, and reconnaissance activities that precede exploitation, enabling teams to block malicious archives before extraction occurs and patch vulnerable Keras installations.
