# GHSA-8cp7-rp8r-mg77: OpenClaw has SSRF guard bypass via IPv6 transition over ISATAP

> Attackers can bypass SSRF protections in OpenClaw to access internal network resources via crafted ISATAP IPv6 URLs.

- **Severity:** Not scored
- **Exploited in the wild:** Not known
- **Login needed:** Not stated
- **Attackable:** Over the internet
- **Victim action needed:** Not needed
- **Fix available:** Yes

## What is GHSA-8cp7-rp8r-mg77?

GHSA-8cp7-rp8r-mg77 is a server-side request forgery vulnerability in openclaw, published on 4 Mar 2026. It can be exploited over the network, with no action from the victim.

### Official description

## Summary
OpenClaw's SSRF hostname/IP guard did not detect ISATAP embedded IPv4 addresses (`...:5efe:w.x.y.z`). A crafted URL containing an ISATAP IPv6 literal could embed a private IPv4 target (for example loopback) and bypass private-address filtering in URL-fetching paths.

## Severity Assessment
Rated **medium**: the bug weakens SSRF protections in URL fetch flows, but impact depends on reaching a URL-fetching path with attacker-controlled input and is generally constrained to internal network access attempts.

## Affected Packages / Versions
- Package: `openclaw` (npm)
- Affected: `>=2026.1.20 <=2026.2.17`
- Latest published at patch time: `2026.2.17`
- Patched release: `2026.2.19`

## Security Policy Context
Per `SECURITY.md`, OpenClaw's web/gateway surface is intended for local use by default, public internet exposure is out-of-scope, and prompt-injection reports are out-of-scope for bounty handling. This advisory tracks a core SSRF-guard bypass in fetch protections.

## Impact
This can permit SSRF-style access attempts to internal/private network targets through URL ingestion/fetch paths that rely on shared hostname/IP blocking.

## Fix
- Added RFC 5214 ISATAP embedded-IPv4 detection to the shared SSRF classifier.
- Centralized hostname/IP blocking through `isBlockedHostnameOrIp` and routed relevant validators to that shared path.
- Added regression tests for ISATAP private vs public embedded IPv4 handling.

## Fix Commit(s)

OpenClaw thanks @zpbrent for reporting.

Check this codebase for GHSA-8cp7-rp8r-mg77 and fix it if it is affected.

What it is: GHSA-8cp7-rp8r-mg77 is a server-side request forgery vulnerability in openclaw, published on 4 Mar 2026. It can be exploited over the network, with no action from the victim.
Exploitation: There is no known exploitation of GHSA-8cp7-rp8r-mg77 in the wild and no public exploit code.

Affected packages and fixed versions:
- openclaw (npm): affected from 2026.1.20; fixed in 2026.2.19
- openclaw (npm): affected from 2026.1.20; fixed in 2026.2.19

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
