Versions 2.61.2 and below are vulnerable to Path Traversal through the resourcePatchHandler (http/resource.go). The destination path in resourcePatchHandler is validated against access rules before being cleaned/normalized, while the actual file operation calls path.Clean() afterward—resolving .. sequences into a different effective path. This allows an authenticated user with Create or Rename permissions to bypass administrator-configured deny rules (both prefix-based and regex-based) by injecting .. sequences in the destination parameter of a PATCH request. As a result, the user can write or move files into any deny-rule-protected path within their scope. However, this cannot be used to escape the user's BasePathFs scope or read from restricted paths. This issue has been fixed in version 2.62.0."}],"source":{"advisory":"GHSA-9f3r-2vgw-m8xp","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-20T20:00:32.489408Z","id":"CVE-2026-32758","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-03-20T20:00:43.633Z"}}]}}
