Summary
Scoold, a Q&A and knowledge sharing platform for teams, has an authorization flaw that allows any logged-in, low-privilege user to overwrite another user's existing question by supplying its public ID as the postId parameter. This affects versions prior to 1.66.2.
Risk Assessment
An attacker can overwrite another user's question content, leading to integrity loss of user-generated content and disruption of existing discussion threads.
Recommendation
It is recommended to update Scoold to version 1.66.2 or later, which includes the fix.
Other vulnerabilities in Scoold
See all- CVE-2026-54677Medium
Scoold is a Q&A and knowledge sharing platform for teams. Prior to 1.69.0, authenticated users who are not members of a private space can create content in questions belonging to that space because QuestionController.reply() and CommentController.createAjax() do not apply the canAccessSpace authorization check used by the question read path. With scoold.is_default_space_public set to false and private spaces in use, a user with a valid session and a known or enumerable question identifier can send requests to POST /question/{id} and POST /comment, causing replies and comments to be stored in a thread the user cannot read.
- CVE-2026-54676Medium
Scoold is a Q&A and knowledge sharing platform for teams. Prior to 1.69.0, users with personal API tokens can retrieve replies from questions in private spaces they cannot access because ApiController.getPostReplies() does not apply canAccessSpace before returning data from GET /api/posts/{id}/answers. The issue is reachable when scoold.api_user_access_enabled and scoold.api_enabled are true and a token holder knows or enumerates a private question identifier. Under those conditions, the question endpoint can deny access while the answers endpoint returns the private reply bodies.
- CVE-2026-34832Medium
Scoold prior to version 1.66.1 does not enforce authorization when deleting feedback – any logged-in user can delete another user's feedback by providing its ID. Object ownership or moderator privileges are not checked.
Original NVD description (English source)
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.
