{"id":"CVE-2026-39354","state":"PUBLISHED","title":"Scoold has an Authenticated Arbitrary Question Overwrite via Client-Controlled postId in POST /questions/ask","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.","publishedAt":"2026-04-07T18:54:36.133Z","updatedAt":"2026-04-09T16:17:51.713Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["Erudika scoold"],"affected":[{"vendor":"Erudika","product":"scoold","versions":[{"version":"< 1.66.2","status":"affected"}]}],"references":["https://github.com/Erudika/scoold/security/advisories/GHSA-768r-cv9p-wrcm"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:11:50.837Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/39xxx/CVE-2026-39354.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-39354","state":"PUBLISHED","datePublished":"2026-04-07T18:54:36.133Z","dateUpdated":"2026-04-09T16:17:51.713Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-04-06T20:28:38.395Z"},"containers":{"cna":{"title":"Scoold has an Authenticated Arbitrary Question Overwrite via Client-Controlled postId in POST /questions/ask","descriptions":[{"lang":"en","value":"Scoold is a Q&A and a knowledge sharing platform for teams.
