CVE-2026-75914: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in Hmbown CodeWhale
CodeWhale versions before 0.8.64 have a path traversal vulnerability in the image_analyze tool. This flaw allows attackers to create symlinks in the workspace that point to external files with image extensions. Because the tool does not canonicalize symlinks before reading files, attackers can leak file contents to the vision endpoint without user approval.
AI Analysis
Technical Summary
CVE-2026-75914 is a path traversal vulnerability in Hmbown's CodeWhale product affecting versions prior to 0.8.64. The vulnerability exists in the image_analyze tool, which fails to canonicalize symbolic links before reading files. This allows an attacker to create workspace symlinks that point to arbitrary external files with image extensions, causing the tool to read and leak file bytes to the vision endpoint without user consent or authorization.
Potential Impact
An attacker can leak contents of arbitrary files on the system by exploiting the path traversal vulnerability. This can lead to unauthorized disclosure of sensitive information. The vulnerability requires no privileges, user interaction, or authentication, and can be exploited remotely over the network. The CVSS 4.0 base score is 8.7 (high severity) reflecting the ease of exploitation and impact on confidentiality.
Mitigation Recommendations
No explicit patch or remediation information is provided in the input data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the image_analyze tool and monitor for suspicious symlink creation in workspaces.
