Reason for change

This advisory for the @sveltejs/kit query.batch cross-talk vulnerability (cross-user data disclosure) includes a CVSS v4.0 score but is missing a CVSS v3.1 score, which many downstream vulnerability scanners and compliance tools still require. It is also missing a reference to the fix commit.

Changes

  • Added CVSS v3.1 score: CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:L/A:N (5.9 — Medium). Rationale: Network-accessible (AV:N), but requires rare timing conditions for exploitation (AC:H), low-privileged attacker (PR:L), and some user interaction (UI:R). High confidentiality impact due to cross-user data disclosure (C:H), low integrity impact (I:L), no availability impact (A:N).
  • Added fix commit reference: sveltejs/kit@dadaefc2e647 — "fix: prevent query.batch cross-talk", merged May 14, 2026.
