CVE-2026-39354: CWE-639: Authorization Bypass Through User-Controlled Key in Erudika scoold
Scoold is a Q&A and a knowledge sharing platform for teams. Prior to 1.66.2, an authenticated authorization flaw in Scoold allows any logged-in, low-privilege user to overwrite another user's existing question by supplying that question's public ID as the postId parameter to POST /questions/ask. Because question IDs are exposed in normal question URLs, a low-privilege attacker can take a victim question ID from a public page and cause attacker-controlled content to be stored under that existing question object. This causes direct integrity loss of user-generated content and corrupts the integrity of the existing discussion thread. This vulnerability is fixed in 1.66.2.
AI Analysis
Technical Summary
Scoold, a Q&A and knowledge sharing platform, contained an authorization flaw (CWE-639) before version 1.66.2 that permitted authenticated low-privilege users to overwrite questions authored by others. The vulnerability arises because the postId parameter in the POST /questions/ask endpoint accepts any existing question's public ID, which is publicly visible in URLs. This enables an attacker to submit malicious content under another user's question, resulting in integrity loss of the content and corruption of discussion threads. The vulnerability is addressed in Scoold version 1.66.2.
Potential Impact
The vulnerability allows low-privilege authenticated users to overwrite existing questions posted by other users, leading to integrity loss of user-generated content and corruption of discussion threads. There is no indication of confidentiality or availability impact. No known exploits in the wild have been reported.
Mitigation Recommendations
Upgrade Scoold to version 1.66.2 or later, where this authorization flaw is fixed. Since this is a self-hosted product, administrators should apply the update promptly to prevent exploitation. Patch status is confirmed by the vendor's versioning information.
