CVE-2026-32055 in OpenClaw
Summary
by MITRE • 03/21/2026
OpenClaw versions prior to 2026.2.26 contain a path traversal vulnerability in workspace boundary validation that allows attackers to write files outside the workspace through in-workspace symlinks pointing to non-existent out-of-root targets. The vulnerability exists because the boundary check improperly resolves aliases, permitting the first write operation to escape the workspace boundary and create files in arbitrary locations.

The vulnerability identified as CVE-2026-32055 affects OpenClaw versions prior to 2026.2.26 and represents a critical path traversal flaw that undermines the fundamental security boundaries of the application's workspace management system. This vulnerability specifically targets the workspace boundary validation mechanisms that are designed to prevent unauthorized file system access and manipulation. The flaw enables attackers to bypass intended security restrictions by exploiting improper handling of symbolic links within the workspace environment. The vulnerability's severity stems from its ability to allow arbitrary file system writes outside of the designated workspace boundaries, potentially enabling persistent access and data exfiltration capabilities.
The technical implementation of this vulnerability occurs through the improper resolution of aliases during workspace boundary validation checks. When the system encounters in-workspace symlinks that point to non-existent targets outside the root directory, the validation logic fails to properly account for these symbolic link traversals. This flaw falls under the CWE-22 category of Path Traversal vulnerabilities, specifically manifesting as an improper input validation issue where the system does not adequately sanitize or resolve symbolic link paths before performing boundary checks. The vulnerability's exploitation requires that attackers create symlinks within the workspace that point to locations outside the intended root scope, leveraging the system's failure to properly resolve these aliases during validation.
The operational impact of this vulnerability extends beyond simple unauthorized file creation, as it provides attackers with the capability to establish persistent access points within the target environment. Once an attacker successfully exploits this vulnerability, they can write malicious files to arbitrary locations on the file system, potentially including system directories, configuration files, or other critical locations. This capability enables various attack vectors including privilege escalation, backdoor installation, and data corruption or theft. The vulnerability's exploitation does not require elevated privileges initially, as the boundary validation is bypassed through the symlink mechanism, allowing attackers to gain access to locations they would normally be restricted from accessing.
Mitigation strategies for CVE-2026-32055 should focus on implementing robust symbolic link resolution and validation within the workspace boundary checking mechanisms. System administrators should immediately upgrade to OpenClaw version 2026.2.26 or later, which contains the necessary patches to address the path traversal vulnerability. Additionally, organizations should implement strict monitoring of workspace directory structures, particularly around symlink creation and modification activities. The mitigation approach aligns with ATT&CK technique T1059.007 for execution through symbolic links and T1566.002 for social engineering via file system manipulation. Security controls should include mandatory validation of all symbolic link targets against workspace boundaries, implementation of file system access controls, and regular auditing of workspace integrity to detect unauthorized symlink creation or modification activities.
