{"id":"CVE-2026-39354","summary":"Scoold has an Authenticated Arbitrary Question Overwrite via Client-Controlled postId in POST /questions/ask","details":"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.","aliases":["GHSA-768r-cv9p-wrcm"],"modified":"2026-07-15T01:49:17.191679367Z","published":"2026-04-07T18:54:36.133Z","database_specific":{"cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/39xxx/CVE-2026-39354.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/39xxx/CVE-2026-39354.json"},{"type":"ADVISORY","url":"https://github.com/Erudika/scoold/security/advisories/GHSA-768r-cv9p-wrcm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-39354"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/erudika/scoold","events":[{"introduced":"0"},{"fixed":"a15fa1b6881a7e1badc05d09bfe807ea173670d8"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.66.2"}],"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:erudika:scoold:*:*:*:*:*:*:*:*"}}],"versions":["1.66.1","1.66.0","1.65.0","1.64.5","1.64.4","1.64.3","1.64.2","1.64.0","1.63.0","1.62.0","1.58.1","1.61.0","1.60.0","1.59.0","1.58.0","1.57.5","1.57.4","1.57.3","1.57.2","1.57.1","1.57.0","1.56.1","1.56.0","1.55.0","1.54.1","1.54.0","1.53.0","1.52.3","1.52.2","1.52.1","1.52.0","1.51.3","1.51.2","1.51.1","1.51.0","1.50.5","1.50.4","1.50.3","1.50.2","1.50.1","1.50.0","1.49.7","1.49.6","1.49.5","1.49.4","1.49.3","1.49.2","1.49.1","1.49.0","1.48.2","1.48.1","1.48.0","1.46.3","1.46.2","1.46.1","1.46.0","1.45.0","1.44.0","1.43.3","1.43.2","1.43.1","1.43.0","1.42.1","1.41.2","1.41.1","1.41.0","1.40.5","1.40.4","1.40.3","1.40.2","1.40.1","1.40.0","1.39.4","1.39.3","1.39.2","1.39.1","1.39.0","1.38.0","1.37.1","1.37.0","1.36.2","1.36.1","1.36.0","1.35.3","1.35.2","1.35.1","1.35.0","1.34.0","1.33.1","1.33.0","1.32.1","1.32.0","1.31.4","1.31.3","1.31.2","1.31.1","1.31.0","1.30.5","1.30.4","1.30.3","1.30.2","1.30.1","1.30.0","1.29.4","1.29.3","1.29.2","1.29.1","1.29.0","1.28.10","1.28.9","1.28.8","1.28.7","1.28.6","1.28.5","1.28.4","1.28.3","1.28.2","1.28.1","1.28.0","1.26.1","1.26.0","1.25.5","1.25.4","1.25.3","1.25.2","1.25.1","1.25.0","1.24.11","1.24.10","1.24.9","1.24.8","1.24.7","1.24.6","1.24.5","1.24.4","1.24.3","1.24.2","1.24.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-39354.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
