The version of Org in my personal that passes a URL-decoded string (i.e. as if run through =url-unhex-string=) as the argument to =org-ql-view--link-open=. But Org 9.3 in Emacs 27.1 passes a non-URL-decoded string, so =org-ql-view--link-open= needs to pass it through =url-unhex-string= itself.
But I don't know which version of Org that changed in. I'm comparing the function =org-open-at-point=, but it's a 114-line function, and in neither version does it call =url-unhex-string=, so whatever code decodes the string must be elsewhere.
I do recall something about links changing in Org 9.3 (or thereabouts), so that was probably part of it. Maybe I can find it in the release notes. I just need to know basically which version it happened in.
I noticed because the CI tests on GitHub show the link-safety tests failing on the Emacs snapshot version. However, I think they're not currently vulnerable on that Org version, because the link parameters fail to be parsed correctly, so all the arguments to =org-ql-search= should end up being nil.

#+BEGIN_QUOTE
Change bracket link escaping syntax
Org used to percent-encode sensitive characters in the URI part of the bracket links.
Now, escaping mechanism uses the usual backslash character, according to the following rules, applied in order:
- All consecutive \ characters at the end of the link must be escaped;
- Any ] character at the very end of the link must be escaped;
- All consecutive \ characters preceding ][ or ]] patterns must be escaped;
- Any ] character followed by either [ or ] must be escaped;
- Others ] and \ characters need not be escaped.
When in doubt, use the function org-link-escape in order to turn a link string into its properly escaped form.
The following function will help switching your links to the new syntax:
(defun org-update-link-syntax (&optional no-query)
"Update syntax for links in current buffer.
Query before replacing a link, unless optional argument NO-QUERY
is non-nil."
(interactive "P")
(org-with-point-at 1
(let ((case-fold-search t))
(while (re-search-forward "\\[\\[[^]]*?%\\(?:2[05]\\|5[BD]\\)" nil t)
(let ((object (save-match-data (org-element-context))))
(when (and (eq 'link (org-element-type object))
(= (match-beginning 0)
(org-element-property :begin object)))
(goto-char (org-element-property :end object))
(let* ((uri-start (+ 2 (match-beginning 0)))
(uri-end (save-excursion
(goto-char uri-start)
(re-search-forward "\\][][]" nil t)
(match-beginning 0)))
(uri (buffer-substring-no-properties uri-start uri-end)))
(when (or no-query
(y-or-n-p
(format "Possibly obsolete URI syntax: %S. Fix? "
uri)))
(setf (buffer-substring uri-start uri-end)
(org-link-escape (org-link-decode uri)))))))))))
The old org-link-escape and org-link-unescape functions have been renamed into org-link-encode and org-link-decode.
#+END_QUOTE
This is exactly the kind of breaking, backwards-incompatible change that I've said should mandate a major-version increment. It's not only a change in Org's code, and a change that affects third-party packages, but it's a change in the file format!
Is it even possible to support both Org 9.3+ and earlier versions at the same time?
This change doesn't even seem to make sense to me. Percent-encoding solves so many problems in a simple way: pass a string to the encoding function on the way in, and to the decoding function on the way out. Now, instead of a simple, standard way of encoding links, there's a list of Org-specific rules and Org-specific encoding/decoding functions. What is gained this way?
