  "details": "Data::Dump::Streamer versions before 3.00 for Perl allow code injection via unescaped Regexp patterns in _dump_qr.\n\nA Regexp's pattern is written into a qr literal without escaping \"$\" or \"@\", so \"@{[ ... ]}\" and \"${\\ ... }\" in the pattern run as code when the dump is evaluated. An already escaped delimiter gets a second backslash, which leaves the delimiter bare and ends the qr literal early.\n\nAn attacker who supplies a pattern that an application compiles, dumps and later restores with eval or do can run arbitrary Perl code.",
