Saltcorn Server allows logged-in users to delete arbitrary files because of a path traversal vulnerability
CVE-2024-47818GHSA-43f3-h63w-p6f6
What to do
Vendor fix available. Upgrade each affected package to the fixed version on its release line (@saltcorn/server 1.0.0-beta.16), redeploy, then verify what is actually installed.
This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description
As published by the source; long descriptions are shortened.
Summary A logged-in user with any role can delete arbitrary files on the filesystem by calling the sync/cleansyncdir endpoint. The dirname POST parameter is not validated/sanitized and is used to construct the syncDir that is deleted by calling fs.rm. Details - file: https://github.com/saltcorn/saltcorn/blob/v1.0.0-beta.15/packages/server/routes/sync.js#L337-L346 PoC The following PoC can be executed with a user with any role (admin, staff, user, public) - create a file in a folder different from where the server is started: - log with a user and retrieve valid connect.sid and csrf values - send the following curl request - check if the file previously created does not exist anymore: obtain connect.sid and csrf values A possible way to retrieve connect.sid and csrf values is to use the password reset functionality: - log in - open the browser developer console, go to the Network tab filter for settings request - visit http://localhost:3000/auth/settings - trigger the change password…

# Patch Next advisory brief: CVE-2024-47818 Advisory: Saltcorn Server allows logged-in users to delete arbitrary files because of a path traversal vulnerability IDs: CVE-2024-47818, GHSA-43f3-h63w-p6f6 Record: https://patchnext.com/advisories/cve-2024-47818 (revision 3, source checked 26 Oct 2026, 12:31 UTC) Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected. Severity: High (CVSS 7.1) Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV. Vendor response: Vendor fix available; fixed versions by package: @saltcorn/server 1.0.0-beta.16. A vendor fix does not mean a deployment is fixed. ## Affected components - npm @saltcorn/server: affected <= 1.0.0-beta.15; fixed in 1.0.0-beta.16 ## Suggested inspection (read-only) - `npm ls @saltcorn/server --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`. ## Supported action Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version. ## Required regression checks - Run the test suite and a production build. - Exercise the features that depend on @saltcorn/server. - Repeat the inspection and confirm that only fixed versions remain installed. ## Rollback considerations - Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward. ## Unresolved questions - Which deployments run an affected version? - Exploitation status can change. Check again before lowering the priority. - Mark the work resolved only after the fixed version is verified in production. ## Sources - Verified: https://osv.dev/vulnerability/GHSA-43f3-h63w-p6f6 (OSV record GHSA-43f3-h63w-p6f6 lists affected ranges: npm @saltcorn/server >=0 <1.0.0-beta.16 (fixed)) - Verified: https://github.com/advisories/GHSA-43f3-h63w-p6f6 (GitHub-reviewed advisory GHSA-43f3-h63w-p6f6 lists affected ranges: npm @saltcorn/server >=0 <=1.0.0-beta.15) Commands are suggestions: review each one before running it.
