A character not seen before at a given state adds an entry that lasts for the life of the matcher.\n\nAn attacker who can submit text with many distinct characters to a long-lived matcher can grow its memory with each search.\n\n## Affected\n\n- `Algorithm-UrataniTakeda >= 0.1.5 < 0.1.7`\n\n## Remediation\n\nUpgrade to Algorithm-UrataniTakeda 0.1.7 or later.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
