Refs: see the GHSA / vendor advisory / patched release linked on this page.
Information disclosure (CWE-200) exists in code.gitea.io/gitea. Attackers reach the vulnerable code path via GET /api/v1/orgs/{org}/labels without authentication.
Check the vendor advisory for the affected versions of code.gitea.io/gitea. Attack surface: GET /api/v1/orgs/{org}/labels / GET /api/v1/orgs/{org}/labels/{id} / GET /api/v1/orgs/{org}/teams / GET /api/v1/orgs/{org}/hooks.
Severity: High (CVSS 7.5/10). Confidential information can be exposed externally.
Update to 1.26.3.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual GET /api/v1/orgs/{org}/labels requests with malformed payloads or SQL meta-characters. Run grep -r 'code.gitea.io/gitea' . 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
-
1Identify exposure identify
grep -r 'code.gitea.io/gitea' . | 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
code.gitea.io/giteaを grep し、稼働しているサービス・バージョンを把握する。 -
2Hunt for indicators of compromise detect
grep 'GET /api/v1/orgs/{org}/labels' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで
GET /api/v1/orgs/{org}/labelsへの異常なリクエスト (不正な認証ヘッダ・SQLメタ文字)を過去 30〜90日分捜索。WAF/SIEM があれば該当パスのアラート発火履歴を確認。 -
3Apply patch patch
Upgrade code.gitea.io/gitea to 1.26.3ステージング環境で 1.26.3 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と、Step 2 で見つけた異常検知の続報チェックを含めること。
-
4Post-deployment verification verify
Replay attack against GET /api/v1/orgs/{org}/labels on staging to confirm patch closes the vector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 Step 2 と同じログクエリでアラート再発が無いか継続監視。
