When a decode filter callback encounters an error with...

AZL-89399 CVE-2026-9516 affecting package perl-Cpanel-JSON-XS 4.39-1

Cpanel::JSON::XS versions before 4.41 for Perl allow denial of service via UTF-8 BOM prefixed input when a decode filter callback throws. To skip a leading 3-byte UTF-8 BOM, decodejson advances the input scalar's string pointer past the mark with SvPVset and restores it only on the normal return...
