Based on the code analysis, it was determined that the /api/member/avatar API endpoint receives a base64 string as input. This string is then passed to the memberService.uploadAvatarByBase64 method for processing. Within the service, the base64-encoded image is parsed. For example, given a string like: data:image/html;base64,PGh0bWw+PGltZyBzcmM9eCBvbmVycm9yPWFsZXJ0KDEpPjwvaHRtbD4= the content after the comma is extracted and decoded using Base64.getDecoder().decode(). The substring from the 11th character up to the first occurrence of a semicolon (;) is assigned to the suffix variable (representing the file extension). The decoded content is then written to a file. However, the file extension is not validated, and since this functionality is exposed to the frontend, it poses significant security risks. \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n  \"Detection Date\": \"06 Jan 2025\",\n  \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2025-01-06T20:17:29.000000Z"}, {"uuid": "8748df8c-651d-4fb9-af3e-69daeaec08a6", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "2a075640-a300-48a4-bb44-bc6130783b9b", "vulnerability": "CVE-2024-56828", "type": "seen", "source": "https://infosec.exchange/users/cve/statuses/113782677540115579", "content": "", "creation_timestamp": "2025-01-06T17:51:16.031071Z"}, {"uuid": "fbde6a2a-d822-4f17-957d-00b870a949a1", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "2a075640-a300-48a4-bb44-bc6130783b9b", "vulnerability": "CVE-2024-56828", "type": "seen", "source": "https://bsky.app/profile/cve-notifications.bsky.social/post/3lf3qjp5kue2a", "content": "", "creation_timestamp": "2025-01-06T18:16:08.415299Z"}, {"uuid": "cacdd3eb-37dd-4f62-805a-4fea0e5e69f8", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "2a075640-a300-48a4-bb44-bc6130783b9b", "vulnerability": "CVE-2024-56828", "type": "seen", "source": "https://bsky.app/profile/cve.skyfleet.blue/post/3lf3s2o2hog2r", "content": "", "creation_timestamp": "2025-01-06T18:43:35.305811Z"}]}
