An unauthenticated attacker can store a crafted, base64-encoded serialized object in wp_comments.comment_content through the standard comment-submission endpoint (wp-comments-post.php). When an administrator subsequently performs a routine Prime Mover export or restore, the plugin base64-decodes that stored value and passes it to unserialize() with no allowed_classes restriction. A Property-Oriented Programming (POP) chain is present in the plugin's own bundled Freemius library (FS_Clone_Manager::__set → FS_Option_Manager::set_option → store() → update_option()), so no additional plugin or theme is required — the plugin ships the gadget itself.", "language": "en", "representation": "source_excerpt" }, { "id": "E2", "sourceUrl": "https://raw.githubusercontent.com/CVEProject/cvelistV5/main/cves/2026/115xxx/CVE-2026-115806.json", "sourceField": "/containers/cna/title", "excerpt": "Prime Mover <= 2.2.1 - Unauthenticated PHP Object Injection via Base64-Encoded Comment during Migration Search-and-Replace", "language": null }, { "id": "E3", "sourceUrl": "https://raw.githubusercontent.com/CVEProject/cvelistV5/main/cves/2026/115xxx/CVE-2026-115806.json", "sourceField": "/containers/cna/affected/0", "excerpt": "{\"vendor\":\"codexonics\",\"product\":\"Prime Mover – Backup and Migration\",\"versions\":[{\"version\":\"0\",\"status\":\"affected\",\"lessThanOrEqual\":\"2.2.1\",\"versionType\":\"semver\"}],\"defaultStatus\":\"unaffected\"}", "language": null, "representation": "source_json" } ], "supportRequest": "件名：CVE-2026-115806（Prime Mover – Backup and Migration）の影響と対応確認\n\n利用中の製品・サービス：[記入してください]\n現在のバージョン・設定：[不明なら「不明」と記入]\n\n次の公式情報にある条件が、私たちの環境に当てはまるか確認をお願いします。\n・攻撃者は認証されていない状態で、標準のコメント投稿エンドポイント（wp-comments-post.php）を利用してコメントを投稿できる必要があります。\n・管理者が Prime Mover のエクスポートまたはリストア機能を実行する必要があります。\n・公式の対象表：codexonics / Prime Mover – Backup and Migration。影響ありとして記載：2.2.1以下の版。\n\n対象の場合、適用する修正・回避策、実施予定、停止や再起動の必要性、完了後の確認結果を教えてください。\n確認している情報：https://zeijaku.ittrip.xyz/vulnerabilities/CVE-2026-115806", "publicationCheckVersion": "2026-10-23.1", "sourceNotices": [], "automation": { "status": "ready", "lastAttempt": "2026-10-24T07:22:21.296Z", "lastSuccess": "2026-10-24T07:22:21.296Z", "sourceCheckedAt": "2026-10-24T07:22:21.296Z", "errorCode": null }, "glossary": [ { "term": "任意のコード実行", "meaning": "攻撃者が用意した処理や命令を、対象のサーバー・機器に実行させられることです。実行できる権限や必要な条件は、個別の説明を確認します。", "sourceUrl": "https://cwe.mitre.org/data/definitions/94.html", "kind": "general_definition" } ] } } }
