Single quotes in the pattern are escaped, but a code block runs in place and needs none.\n\nAn attacker who supplies a query, or text that an application inserts into the pattern of one, can execute arbitrary Perl code in the calling process.\n\n## Affected\n\n- `JQ-Lite < 2.51`\n\n## Remediation\n\nUpgrade to JQ-Lite 2.51 or later.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
