Vulnerability in go.opentelemetry.io/obi (CVE-2026-45679)

Summary

Vulnerability in go.opentelemetry.io/obi (CVE-2026-45679). Risk of unauthorized operations or information disclosure. Exploitable via getRedisError. Mitigation: upgrade to 0.9.0 or later.

Original description

The description as published by the source.

Summary

OBI exports raw Redis error text as the span status message. Because Redis error replies can contain attacker-controlled or sensitive values, this behavior can exfiltrate tokens, PII, or other confidential input into telemetry backends and inject untrusted text into downstream analysis systems.

Details

In pkg/ebpf/common/redis_detect_transform.go, getRedisError trims the raw error buffer and stores it directly in request.DBError.Description.

Later, pkg/appolly/app/request/span.go returns that description as the exported status message for Redis spans whenever the span status is non-zero.

There is no opt-in control or sanitization beyond CRLF trimming. As a result, raw Redis error text becomes part of OTLP-exported status metadata by default.

PoC

Local request-layer testing recorded a status message containing ERR invalid password for user bob secret=TOPSECRET, which shows that unfiltered Redis error text reaches the exported status message.

Use a vulnerable build:

git checkout v0.0.0-rc.1+build
make build

Start Redis and OBI:

docker run --rm -p 6379:6379 redis:7
sudo ./bin/obi

❓ What is the problem

A vulnerability (CWE-117) exists in go.opentelemetry.io/obi. Attackers reach the vulnerable code path via getRedisError without authentication.

📍 Affected scope

Check the vendor advisory for the affected versions of go.opentelemetry.io/obi. Attack surface: getRedisError / request.DBError.Description.

🔥 Severity

Severity: Medium (CVSS 6.5/10). Risk of unauthorized operations or information disclosure.

🔧 How to fix

Update to 0.9.0.

🛡️ 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 'go.opentelemetry.io/obi' . 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 'go.opentelemetry.io/obi' . | 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 go.opentelemetry.io/obi 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 go.opentelemetry.io/obi to 0.9.0

    ステージング環境で 0.9.0 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。
