Summary
BBOT: Symlink-Following Arbitrary Write via github_workflows Module
Details

The github_workflows module constructs local directory paths from user-controlled repository names without validating for symlinks. A local attacker sharing the scan directory can plant a symlink at the predictable output path, causing workflow data to be written to an attacker-chosen location.

Summary
OpenClaw's avatar symlink traversal can expose out-of-workspace local files
Details

Summary

OpenClaw avatar handling allowed a symlink traversal path that could expose local files outside an agent workspace through gateway avatar surfaces.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected versions: <= 2026.2.21, plus prereleases 2026.2.21-1 and 2026.2.21-2
  • Latest published version at triage time (2026-02-22): 2026.2.21-2 (affected)
  • Planned patched version (pre-set for release workflow): 2026.2.22

Details

In vulnerable builds, local avatar resolution could follow symlinks and return file bytes from outside the configured workspace boundary.

The issue was hardened in two paths: 1. Gateway avatar metadata resolution now enforces canonical containment, O_NOFOLLOW, and fd/file-identity checks. 2. Control UI avatar serving now rejects symlink paths and enforces fd/file-identity and size checks before reads.

Fix Commit(s)

  • 3d0337504349954237d09e4d957df5cb844d5e77
  • 6970c2c2db3ee069ef0fff0ade5cfbdd0134f9d2

Release Process Note

patched_versions is pre-set to >= 2026.2.22 so after npm release, the remaining action is to publish this advisory.

Impact

Confidentiality impact only: local files readable by the OpenClaw process could be disclosed via avatar response surfaces.

OpenClaw thanks @tdjackey for reporting.

Mitigation MIT-48.1
Architecture and Design

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.
