Which packages are affected by GHSA-67rw-2x62-mqqm?

GHSA-67rw-2x62-mqqm affects the following packages: copyparty (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-67rw-2x62-mqqm?

Update copyparty to 1.20.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-67rw-2x62-mqqm is resolved across your whole dependency graph.

How do I detect GHSA-67rw-2x62-mqqm in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for copyparty, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-67rw-2x62-mqqm if there is no patch (or I can't update yet)?

Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Is GHSA-67rw-2x62-mqqm actively exploited in the wild?

No public exploit code has been indexed for GHSA-67rw-2x62-mqqm yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-67rw-2x62-mqqm?

Description

There was a missing permission-check in the shares feature (the shr global-option).

This vulnerability only applies in the following scenario:

The shares feature is used for the specific purpose of creating a share of just a single file inside a folder
Either the FTP or SFTP server is enabled, and also made publically accessible
- If a share is password-protected, then SFTP was not vulnerable unless the sftp-pw global-option was also enabled

Given these conditions, when a user is browsing a share through either FTP or SFTP (not http or https), they can gain read-access to the remaining files inside the shared folder by guessing/bruteforcing the filenames.

It was not possible to descend into subdirectories in this manner; only the sibling files were accessible.

This issue did not affect filekeys or dirkeys.

This vulnerability is CVE-2025-58753 which was previously fixed for HTTP and HTTPS, but not for FTP. The FTPS server did not yet exist at that time.
