Radu Cotescu commented on SLING-7741:
-------------------------------------
The PR [0] should solve this issue, however the current set of regexes doesn't
validate some correctly formed URIs (for example the {{:}} character can be
used anywhere inside a URI).
A nicer approach would have been the [^SLING-7741.correct_uri_parsing.patch]
(which can be applied on top of [commit
43947bd|[https://github.com/apache/sling-org-apache-sling-xss/commit/43947bd]),]
however the URI grammar (reproduced through the regexes added to the patch)
cannot make a difference between a {{scheme:// }}and a path containing {{:}},
followed by two empty segments.
