# Security Advisory: High Severity Vulnerabilities - May 30, 2026

This advisory addresses 3 HIGH severity vulnerabilities identified by Vanta security scans.

## Summary

| CVE | Package | Severity | CVSS | Status | Fixed Version |
|-----|---------|----------|------|--------|---------------|
| CVE-2026-29063 | immutable | HIGH | 9.8 | OVERDUE | 5.1.5 |
| CVE-2025-58754 | axios | HIGH | 8.2 | OVERDUE | 1.12.0 |
| CVE-2026-32460 | langsmith | HIGH | 7.1 | Due Jun 12 | 0.6.0 |

## Vulnerability Details

### 1. CVE-2026-29063: Prototype Pollution in immutable

**Location:** Transitive dependency in `openmemory/ui`  
**Current Version:** 5.1.1  
**Required Version:** >= 5.1.5

**Impact:**
- Prototype pollution via `mergeDeep()`, `mergeDeepWith()`, `merge()`, `Map.toJS()`, `Map.toObject()`
- Privilege escalation through `__proto__` injection
- Security check bypass

**Remediation:**
Since immutable is a transitive dependency, investigate the dependency tree and either:
1. Update the direct dependency that requires immutable
2. Use package manager overrides/resolutions:

```json
// pnpm-lock.yaml or package.json
"pnpm": {
  "overrides": {
    "immutable": ">=5.1.5"
  }
}
```

- Advisory: https://github.com/immutable-js/immutable-js/security/advisories/GHSA-wf6x-7x77-mvgw

### 2. CVE-2025-58754: Axios DoS via data: URI

**Location:** Multiple locations (already fixed in most)  
**Current Versions:** 1.15.2, 1.7.7 (SAFE)  
**Required Version:** >= 1.12.0

**Status:** ✅ RESOLVED - All axios instances are already at safe versions

**Impact:**
- Denial of Service through unbounded memory allocation
- Process crash via malicious `data:` URIs
- Bypasses `maxContentLength` / `maxBodyLength` limits

**Verification:**
```bash
grep -r "axios" --include="package.json" | grep version
# All instances show >= 1.12.0
```

- Dependabot: https://github.com/mem0ai/mem0/security/dependabot/567

### 3. CVE-2026-32460: LangSmith SSRF & Credential Disclosure

**Location:** Transitive dependency in `openclaw` and `mem0-ts`  
**Current Versions:** 0.3.87, 0.5.10  
**Required Version:** >= 0.6.0

**Impact:**
- Server-Side Request Forgery (SSRF) via untrusted prompts
- Credential disclosure when pulling public prompts
- Prompt injection and behavior manipulation

**Remediation:**
Since langsmith is a transitive dependency (likely from @langchain packages), investigate and either:
1. Update the parent dependency (@langchain/core, etc.)
2. Use package manager overrides:

```json
// pnpm-lock.yaml or package.json
"pnpm": {
  "overrides": {
    "langsmith": ">=0.6.0"
  }
}
```

**Post-Upgrade Security Guidance:**
After upgrading, pulling public prompts requires explicit opt-in:
- Python: `dangerously_pull_public_prompt=True`
- JS/TS: `dangerouslyPullPublicPrompt: true`

**References:**
- Issue: #5320
- Dependabot: https://github.com/mem0ai/mem0/security/dependabot/920
- Advisory: https://github.com/langchain-ai/langsmith-sdk/security/advisories/GHSA-3644-q5cj-c5c7

## Recommended Actions

### Immediate (High Priority - Overdue)
1. ✅ **CVE-2025-58754 (axios):** Already resolved - verify in production
2. 🔴 **CVE-2026-29063 (immutable):** Add override to `openmemory/ui/package.json`
3. 🔴 **CVE-2026-32460 (langsmith):** Add overrides to `openclaw/package.json` and `mem0-ts/package.json`

### Testing Checklist
- [ ] Run `pnpm install` in affected directories
- [ ] Verify lock files show updated versions
- [ ] Run existing test suites
- [ ] Check for runtime errors related to dependency changes
- [ ] Verify Dependabot alerts are resolved

### Deployment Verification
```bash
# After deployment, verify versions:
cd openmemory/ui && pnpm list immutable
cd openclaw && pnpm list langsmith
cd mem0-ts && pnpm list langsmith
```

## Implementation Plan

1. **Add Dependency Overrides**
   - Update `openmemory/ui/package.json` with immutable override
   - Update `openclaw/package.json` with langsmith override
   - Update `mem0-ts/package.json` with langsmith override

2. **Regenerate Lock Files**
   ```bash
   cd openmemory/ui && pnpm install
   cd openclaw && pnpm install
   cd mem0-ts && pnpm install
   ```

3. **Test & Verify**
   - Run test suites for each affected package
   - Verify no breaking changes
   - Check Vanta dashboard for resolution

4. **Deploy & Monitor**
   - Deploy to staging first
   - Monitor for any runtime issues
   - Deploy to production
   - Confirm Dependabot alerts close
