CVE-2026-62680 high CVSS 7.1

Path Traversal in orval (CVE-2026-62680)

Summary

Path traversal in orval (CVE-2026-62680). Confidential information can be exposed externally. Exploitable via orval. Mitigation: upgrade to 8.22.0 or later.

Original description

The description as published by the source.

Summary

Orval resolves OpenAPI $refs by fetching remote http(s) URLs and reading local files (including
absolute / out-of-tree paths), inlining the referenced schema into the generated client. Running
orval on a spec whose $ref points at an attacker/internal URL or an arbitrary local file yields
SSRF, remote file inclusion, and local file inclusion. Verified on 8.19.0. This is a different class
from Orval's published output-injection CVEs (CVE-2026-22785/23947/24132/25141), none of which covers
the $ref resolver.

Details

  • $ref: http://attacker/internal-evil.json#/... → build host fetches (SSRF) and inlines the remote
    schema (RFI); confirmed property REMOTE_ORVAL_PROP in the generated client.
  • $ref: /abs/path.json#/... or ../../secret.json#/... → out-of-tree local file read + inlined (LFI).

No RCE: on 8.19.0 the description JSDoc is escaped (*/->*\/, the published fix), so $ref content
cannot break out into code. The chain stops at SSRF + RFI + LFI.

Fix: don't resolve remote $refs by default (opt-in + host allowlist); confine local $ref
resolution to the input directory tree (reject absolute paths and ../ escapes).

PoC

reproduce.sh attached: confirms LFI (out-of-tree read), SSRF (listener hit), RFI (remote schema
inlined). Verified on Orval 8.19.0.

Impact

Build-time SSRF from the developer or CI host, disclosure of arbitrary local files, and inclusion of untrusted remote content, from running the generator on an atta…

CVE-2026-62680 (orval) — CWE-22 / CVSS v3 7.1
Attack vector: remote (network-reachable) / unauthenticated
Attack surface: orval / REMOTE_ORVAL_PROP / reproduce.sh
Patched: 8.22.0 — apply immediately
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.

❓ What is the problem

Path traversal (CWE-22) exists in orval. Attackers reach the vulnerable code path via orval without authentication.

📍 Affected scope

Check the vendor advisory for the affected versions of orval. Attack surface: orval / REMOTE_ORVAL_PROP / reproduce.sh.

🔥 Severity

Severity: High (CVSS 7.1/10). Confidential information can be exposed externally.

🔧 How to fix

Update to 8.22.0.

🛡️ Workaround

Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.

🔍 Detection

Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r 'orval' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify 
    grep -r 'orval' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で orval を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Apply patch patch 
    Upgrade orval to 8.22.0

    ステージング環境で 8.22.0 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスを含めること。

  3. 3
    Post-deployment verification verify 
    Confirm patched version is live in production

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。

Affected packages
