CVE ID :CVE-2026-64193<\/p>\n
Published : July 20, 2026, 7:17 p.m. | 27\u00a0minutes ago<\/p>\n
Description :Net::DNS versions through 1.55 for Perl allow remote execution injection via EDNS EXTENDED ERROR.<\/p>\n
Net::DNS::RR::OPT::EXTENDED_ERROR::_decompose parses the EXTRA-TEXT field of an EDNS EXTENDED-ERROR option (RFC 8914) by tokenising the raw bytes and passing the result to Perl’s eval. There is some escaping done for $ and @, but not for backticks. This can be exploited for command execution if $pkt->edns->option(‘EXTENDED-ERROR’) is called in array context, for example with a payload of {0:`””`} in EXTRA-TEXT.<\/p>\n
Severity: 0.0 | NA<\/p>\n
