CVE-2026-15626
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability was determined in nextlevelbuilder GoClaw 3.13.3-beta.3. This affects the function writeFile of the file internal/providers/acp/tool_bridge.go of the component ACP ToolBridge Workspace Handler. This manipulation causes path traversal. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA path traversal vulnerability exists in the writeFile function of GoClaw's ACP ToolBridge Workspace Handler (internal/providers/acp/tool_bridge.go). The function fails to properly validate file paths, allowing attackers to use '../' sequences to write files outside the intended directory.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the vulnerable fileSearch for the file internal/providers/acp/tool_bridge.go in your GoClaw installation and confirm its presenceAffected if The file exists and contains a writeFile function related to ACP ToolBridge Workspace Handler
-
Identify writeFile usageInspect the writeFile function in tool_bridge.go and determine if it handles user-supplied file pathsAffected if The function accepts file path parameters without sanitization
-
Check for path validation logicReview the writeFile function code for path traversal checks such as filepath.Clean, filepath.Base, or explicit '../' rejectionAffected if No path validation or traversal sequence filtering is implemented in the writeFile function
-
Verify input sourceTrace how file paths reach the writeFile function - check if they come from user requests, API calls, or configurationAffected if Untrusted input can reach the writeFile function without validation
-
Confirm workspace directory configurationIdentify the intended base directory for workspace file operations and check if path boundaries are enforcedAffected if The writeFile function can write outside the designated workspace directory
Your environment is affected if the GoClaw ACP ToolBridge is deployed with the vulnerable tool_bridge.go file containing a writeFile function that processes unvalidated file paths and lacks directory traversal protections.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict path validation in the writeFile function to ensure all file paths resolve within the intended workspace directory, rejecting any path containing directory traversal sequences or resolving to locations outside the allowed base directory.
