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."}], "lastModified": "2026-04-10T19:29:30.457", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:erudika:scoold:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "8F1340F2-5D49-4F87-B3DB-2187E5842588", "versionEndExcluding": "1.66.2"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
