CVE-2026-48777

CVE-2026-48777 — FileBrowser Quantum has a path-traversal in the public share PATCH endpoint. Versions prior to 1.3.2-stable, 1.4.0-beta, and 1.4.1-beta allow an attacker with a public share link that has AllowModify=true to move, copy, or rename files outside the share root by abusing publicPatc...

FileBrowser Quantum: Path traversal in public share PATCH allows file ops outside shared directory

Summary publicPatchHandler in backend/http/public.go joins user-controlled fromPath and toPath body fields with the trusted d.share.Path BEFORE the downstream sanitizer runs. Because filepath.Join collapses .. segments during the join, the sanitizer in resourcePatchHandler never sees the traversa...

CVE-2026-44542

FileBrowser Quantum is a free, self-hosted, web-based file manager. Prior to 1.3.1-stable and 1.3.9-beta, attacker-controlled path input is joined with a trusted base path prior to sanitization, allowing traversal sequences e.g., ../ to escape the intended shared directory. As a result, an...

Directory Traversal

github.com/gtsteffaniak/filebrowser is vulnerable to Directory Traversal. The vulnerability is due to improper sanitization of attacker-controlled path input before path validation, which allows an attacker to use traversal sequences to delete arbitrary files outside the intended shared directory...

GHSA-Q49M-57VM-C8CC Kata Container has CopyFile Policy Subversion via Symlinks

Summary An oversight in the CopyFile policy and perhaps the CopyFile handler allows untrusted hosts to write to arbitrary locations inside the guest workload image. This can be used to overwrite binaries inside the guest and exfiltrate data from containers; even those running inside CVMs. Details...

Name of the Vulnerable Software and Affected Versions FileBrowser Quantum versions prior to 1.3.1-stable FileBrowser Quantum versions prior to 1.3.9-beta Description Attacker-controlled path input is joined with a trusted base path before sanitization, enabling the use of traversal sequences such...

UNIX Symbolic Link (Symlink) Following

Overview Affected versions of this package are vulnerable to UNIX Symbolic Link Symlink Following via the WebDAV backend process. An attacker can access and modify files outside the intended directory by exploiting symbolic links that point outside the designated root. This is only exploitable if...

EUVD-2025-208410

If two sibling jails are restricted to separate filesystem trees, which is to say that neither of the two jail root directories is an ancestor of the other, jailed processes may nonetheless be able to access a shared directory via a nullfs mount, if the administrator has configured one. In this...

CVE-2025-15576

CVE-2025-15576 describes a jail/chroot escape in FreeBSD. When two sibling jails are restricted to separate filesystem trees, processes in the two jails can still exchange directory descriptors via a unix domain socket and access a shared directory mounted with nullfs. During a filesystem name lo...
