Security readout for executives and security teams
Plain-English summary
OpenClaw versions before 2026.3.7 may leak sensitive custom authorization headers when a request is redirected to another origin. An attacker-controlled redirect could receive headers such as X-Api-Key or Private-Token that were meant only for the original service.
Executive priority
Treat this as urgent for any production OpenClaw deployment using service tokens or API keys. The main business risk is credential exposure leading to downstream data access. No cited source confirms exploitation, but the severity and ease of triggering redirects justify rapid upgrade and credential review.
Technical view
The issue is in fetchWithSsrFGuard. It improperly forwards custom authorization headers across cross-origin redirects, creating credential disclosure risk. CVSS is 9.3 with network attack vector, low complexity, no privileges, no user interaction, changed scope, high confidentiality impact, and low integrity impact.
Likely exposure
Organizations using OpenClaw before 2026.3.7 are exposed, especially where OpenClaw sends custom API or private token headers to external services that may redirect requests across origins.
Exploitation context
The bundle does not cite active exploitation, and KEV is false. Exploitation would depend on causing OpenClaw-handled requests with sensitive custom headers to follow cross-origin redirects controlled or observable by an attacker.
Researcher notes
Keep scope limited to OpenClaw before 2026.3.7 and the documented fetchWithSsrFGuard behavior. The provided evidence supports header leakage across cross-origin redirects, not arbitrary token theft across unrelated products. Use the patch commit to understand the exact header validation change.
Mitigation direction
- Upgrade OpenClaw to 2026.3.7 or later.
- Review the GitHub advisory and patch commit for vendor-confirmed remediation details.
- Rotate custom API keys or private tokens that may have crossed untrusted redirects.
- Audit integrations that send X-Api-Key, Private-Token, or similar custom headers.
- Check vendor guidance before applying any non-vendor workaround.
Validation and detection
- Inventory deployed OpenClaw versions and flag anything before 2026.3.7.
- Identify uses of fetchWithSsrFGuard with custom authorization-like headers.
- Verify cross-origin redirects no longer receive sensitive custom headers after upgrade.
- Review logs for unexpected cross-origin redirects involving token-bearing requests.
- Confirm token rotation completed for potentially exposed integrations.

Insufficiently Protected Credentials
Insufficiently Protected Credentials represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
