CVE-2026-110766
Colanode server through 0.4.7 contains a path traversal vulnerability that allows authenticated users to read arbitrary .jpeg files by supplying an encoded traversal sequence in avatarId.
Does this matter?
Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.
Description
Colanode server through 0.4.7 contains a path traversal vulnerability that allows authenticated users to read arbitrary .jpeg files by supplying an encoded traversal sequence in avatarId. Attackers can send percent-encoded ../ sequences to GET /client/v1/avatars/:avatarId to escape the avatars directory and read .jpeg files belonging to other workspaces.
