CVE-2026-88940 Details
Description
knowns through 0.33.0 fails to validate the path query parameter in the workspace browse endpoint, allowing remote attackers to enumerate arbitrary directories on the host filesystem. Attackers can traverse the directory structure to locate project directories and identify targets for further exploitation.
A directory enumeration vulnerability has been identified in the Knowns application, specifically in versions through 0.33.0. The issue arises because the workspace browse endpoint fails to properly validate the path query parameter. This oversight allows remote attackers to traverse the directory structure of the host filesystem, potentially leading to further exploitation. The vulnerability is rooted in unvalidated path queries, which can be exploited to locate project directories by returning absolute paths of any valid Knowns projects found.
To address this vulnerability, the browse endpoint should be modified to include proper path validation, ensuring that only authorized directories are accessible.
