DescriptionCVE.org

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.

AnalysisAI

Directory traversal in knowns through 0.33.0 exposes arbitrary host filesystem paths to unauthenticated remote attackers via the workspace browse endpoint's unsanitized path query parameter. Attackers can walk the directory tree to map project directories, configuration file locations, and other filesystem structures without any credentials or special privileges. …

Vulnerability AssessmentAI

Exploitation The knowns workspace browse HTTP endpoint must be reachable over the network. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N) accurately captures the threat model: zero-friction unauthenticated network exploitation with impact capped at limited confidentiality (directory names, not file content). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Consult the vendor security advisory at https://github.com/knowns-dev/knowns/security/advisories/GHSA-h73x-698r-qrvg for the officially patched release version; no specific fixed version number is confirmed in the available input data. … Detailed patch versions, workarounds, and compensating controls in full report.
