Official Description

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.

Technical Analysis

CVE-2026-39354 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in full integrity compromise (data manipulation), with a CVSS base score of 6.5.
