SCA: security update for prosemirror-view (GHSA-c8x8-7fp4-3x9w)

high Tenable Cloud Security Plugin ID 472978

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - ProseMirror's view component renders and manages the editable browser interface for ProseMirror documents.
 Prior to 1.42.3, prosemirror-view paste handling accepts attacker-provided HTML whose clipboard slice
 context contains attributes that are not passed through schema attribute validation. When a user pastes
 the crafted HTML into an editor, the unvalidated context attributes can construct content that executes
 attacker-controlled JavaScript in the browser window containing the editor. This issue is fixed in version
 1.42.3. (CVE-2026-104847)

Solution

Update the prosemirror-view library and its related packages to version 1.42.3 or later.
