A GitHub-reviewed security advisory, not necessarily under active exploitation the way our CISA KEV advisories are, but a real, disclosed vulnerability in an open-source dependency.
Affected packages
Vulnerable: >= 2.5.0, <= 2.7.5
Patched in 2.7.6
Details
File pattern filters (denied_patterns / allowed_patterns) were evaluated on the destination of a copy only. A user holding the copy permission could copy a file denied by the filters to a permitted name and then read it. A recursive directory copy reproduced the contents of a restricted directory under a path where the filters do not deny them, and the hide policy was affected in the same way: a file reported as missing by stat and by directory listings could still be copied.
An authenticated user can read the contents of files that the file pattern filters are configured to deny them. Nothing else is bypassed: the home directory, the virtual folder layout and the per-directory permissions are all still enforced, and both ends of the copy are paths the account can already reach. No access to other accounts and no administrative capability.
EPSS, exploit probability
Low0.22%
estimated chance of real-world exploitation in the next 30 days, higher than 11.5% of every CVE FIRST.org scores
Refreshed 10/15/2026, via FIRST.org's EPSS model, not CVSS, this measures likelihood of exploitation, not how severe it would be.
