Title
OpenClaw < 2026.2.22 - Arbitrary File Read via Symlink Following in Static File Handler
Summary
OpenClaw versions prior to 2026.2.22 contain a path traversal vulnerability in the static file handler that follows symbolic links, allowing out-of-root file reads. Attackers can place symlinks under the Control UI root directory to bypass directory confinement checks and read arbitrary files outside the intended root.

OpenClaw < 2026.2.22 - Symlink Traversal in Avatar Handling
Summary
OpenClaw versions prior to 2026.2.22 contain a symlink traversal vulnerability in avatar handling that allows attackers to read arbitrary files outside the configured workspace boundary. Remote attackers can exploit this by requesting avatar resources through gateway surfaces to disclose local files accessible to the OpenClaw process.

Summary
OpenClaw versions prior to 2026.2.25 contain a symlink traversal vulnerability in browser trace and download output path handling that allows local attackers to escape the managed temp root directory. An attacker with local access can create symlinks to route file writes outside the intended temp directory, enabling arbitrary file overwrite on the affected system.

Title
BuildKit Git URL subdir component can cause access to restricted files
Summary
BuildKit is a toolkit for converting source code to build artifacts in an efficient, expressive and repeatable manner. Prior to version 0.28.1, insufficient validation of Git URL fragment subdir components may allow access to files outside the checked-out Git repository root. Possible access is limited to files on the same mounted filesystem. The issue has been fixed in version v0.28.1 The issue affects only builds that use Git URLs with a subpath component. As a workaround, avoid building Dockerfiles from untrusted sources or using the subdir component from an untrusted Git repository where the subdir component could point to a symlink.

Title
Claude SDK for Python: Memory Tool Path Validation Race Condition Allows Sandbox Escape
Summary
The Claude SDK for Python provides access to the Claude API from Python applications. From version 0.86.0 to before version 0.87.0, the async local filesystem memory tool in the Anthropic Python SDK validated that model-supplied paths resolved inside the sandboxed memory directory, but then returned the unresolved path for subsequent file operations. A local attacker able to write to the memory directory could retarget a symlink between validation and use, causing reads or writes to escape the sandbox. The synchronous memory tool implementation was not affected. This issue has been patched in version 0.87.0.

@tinacms/graphql's Media Endpoints Can Escape the Media Root via Symlinks or Junctions
Summary
Tina is a headless content management system. Prior to version 2.2.2, @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. This issue has been patched in version 2.2.2.

CVE-2026-34604 (GCVE-0-2026-34604)

Title
@tinacms/graphql's `FilesystemBridge` Path Validation Can Be Bypassed via Symlinks or Junctions
Summary
Tina is a headless content management system. Prior to version 2.2.2, @tinacms/graphql uses string-based path containment checks in FilesystemBridge. That blocks plain ../ traversal, but it does not resolve symlink or junction targets. If a symlink/junction already exists under the allowed content root, a path like content/posts/pivot/owned.md is still considered "inside" the base even though the real filesystem target can be outside it. As a result, FilesystemBridge.get(), put(), delete(), and glob() can operate on files outside the intended root. This issue has been patched in version 2.2.2.

Mitigation ID: MIT-48.1
Phase: Architecture and Design
Strategy: Separation of Privilege
Description:
- 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.
