CVE-2026-39354

Estado: AnalizadaMedia (6.5)—

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.

Debido a que los ID de las preguntas están expuestos en las URL normales de las preguntas, un atacante de bajo privilegio puede tomar el ID de una pregunta de la víctima de una página pública y hacer que el contenido controlado por el atacante se almacene bajo ese objeto de pregunta existente.
