The segment is created in roaring.h with open(path, O_RDWR|O_CREAT, 0666). The mode is 0666, so under the default umask 022 the file is created mode 0644 (world-readable). O_NOFOLLOW is absent, so a symlink planted at the path is followed, and O_EXCL is absent, so the open silently uses a pre-planted file instead of failing.
A "Shared" segment naturally lives in a shared directory such as /tmp or /dev/shm, where any local user can read the IPC payloads stored in the world-readable segment, and a pre-planted file or symlink at the path lets a local attacker win a pre-creation race or redirect the open.

GHSA-G87C-R2JP-293W
Vulnerability from github – Published: 2026-04-01 00:23 – Updated: 2026-04-06 16:44Summary
@tinacms/cli recently added lexical path-traversal checks to the dev media routes, but the implementation still validates only the path string and does not resolve symlink or junction targets.
If a link already exists under the media root, Tina accepts a path like pivot/written-from-media.txt as "inside" the media directory and then performs real filesystem operations through that link target. This allows out-of-root media listing and write access, and the same root cause also affects delete.
Details
The dev media handlers validate user-controlled paths with:
function resolveWithinBase(userPath: string, baseDir: string): string {
const resolvedBase = path.resolve(baseDir);
const resolved = path.resolve(path.join(baseDir, userPath));
if (resolved === resolvedBase) {
return resolvedBase;
}
if (resolved.startsWith(resolvedBase + path.sep)) {
return resolved;
}
throw new PathTraversalError(userPath);
}
function resolveStrictlyWithinBase(userPath: string, baseDir: string): string {
const resolvedBase = path.resolve(baseDir) + path.sep;
const resolved = path.resolve(path.join(baseDir, userPath));
if (!resolved.startsWith(resolvedBase)) {
throw new PathTraversalError(userPath);
}
return resolved;
}
But the validated path is then used directly for real filesystem access:
filesStr = await fs.readdir(validatedPath);
...
await fs.ensureDir(path.dirname(saveTo));
file.pipe(fs.createWriteStream(saveTo));
...
await fs.remove(file);
This does not account for symlinks/junctions already present below the media root. A path such as pivot/secret.txt can be lexically inside the media directory while the filesystem target is outside it.
Local Reproduction
I verified this locally with a real junction on Windows.
Test layout:
- media root:
D:\bugcrowd\tinacms\temp\junction-repro4\public\uploads - junction under media root:
public\uploads\pivot -> D:\bugcrowd\tinacms\temp\junction-repro4\outside - file outside the media root:
outside\secret.txt
Tina's current media-path validation logic was applied and used to perform the same list/write operations the route handlers use.
Observed result:
{
"media": {
"base": "D:\\bugcrowd\\tinacms\\temp\\junction-repro4\\public\\uploads",
"resolvedListPath": "D:\\bugcrowd\\tinacms\\temp\\junction-repro4\\public\\uploads\\pivot",
"listedEntries": [
"secret.txt"
],
"resolvedWritePath": "D:\\bugcrowd\\tinacms\\temp\\junction-repro4\\public\\uploads\\pivot\\written-from-media.txt",
"outsideWriteExists": true,
"outsideWriteContents": "MEDIA_ESCAPE"
}
}
This shows the problem clearly:
- the path validator accepted
pivot - listing revealed a file from outside the media root
- writing to
pivot/written-from-media.txtcreatedoutside\written-from-media.txt
The delete path uses the same flawed containment model and should be hardened at the same time.
Impact
- Out-of-root file listing via
/media/list/... - Out-of-root file write via
/media/upload/... - Likely out-of-root file delete via
/media/...DELETE, using the same path-validation gap - Bypass of the recent path traversal hardening for any deployment whose media tree contains a link to another location
This is especially relevant in development and self-hosted workflows where the media directory may contain symlinks or junctions intentionally or via repository content.
Recommended Fix
Harden media path validation with canonical filesystem checks:
- resolve the real base path with
fs.realpath() - resolve the real target path, or for writes the nearest existing parent
- compare canonical paths rather than lexical strings
- reject any operation that traverses through a symlink/junction to leave the real media root
path.resolve(...).startsWith(...) is not sufficient for filesystem security on linked paths.

Mitigation MIT-48.1
Strategy: Separation of Privilege
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
CAPEC-132: Symlink Attack
An adversary positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name.
CAPEC-17: Using Malicious Files
An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
CAPEC-35: Leverage Executable Code in Non-Executable Files
An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
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.
