static/jquery/jquery.js was jQuery 1.12.4 (2016), loaded by templates/core.html
on every page of the operator UI. Affected by:

  * CVE-2015-9251 — XSS via cross-domain Ajax responses (fixed in jQuery 3.0)
  * CVE-2019-11358 — prototype pollution in $.extend (fixed in 3.4)
  * CVE-2020-11022 — XSS via HTML manipulation methods (.html, .append, etc.)
  * CVE-2020-11023 — XSS via <option> elements in HTML manipulation
                     (the latter two fixed in 3.5)

Replaced with jQuery 3.7.1 (current stable), downloaded from code.jquery.com
and cross-verified against cdn.jsdelivr.net:

  SHA-256 78a85aca2f0b110c29e0d2b137e09f0a1fb7a8e554b499f740d6744dc8962cfe

static/jquery/jquery.min.js was a stale 3.3.1 copy not referenced by any
template (verified with `grep -r 'jquery.min'`); deleted rather than upgraded.

jquery.multi-select.js (v0.9.12) is unchanged — it works against jQuery 3.x.

Reported externally on 2026-05-18.
