  "title": "Quadratic-time denial of service in re2js lookbehind matching",
  "summary": "re2js before 2.8.7 can consume excessive CPU when lookbehind matching is enabled and repeated-match APIs process attacker-controlled text. An attacker may use this condition to block a Node.js worker and disrupt service; applications are affected when they enable `LOOKBEHINDS` and use operations such as repeated searches, splitting, or replacement on untrusted input.",
  "mitigation": "Upgrade re2js to version 2.8.7 or later. Until upgraded, disable lookbehind use for untrusted input and limit the size of text sent to repeated-matching operations.",
