  "title": "Out-of-bounds read in Tencent RapidJSON regex parsing",
  "summary": "Tencent RapidJSON versions through 1.1.0 contain an out-of-bounds read in regex parsing functionality. A remote attacker may be able to trigger the issue if they can cause an application to process untrusted data through that functionality; the precise triggering conditions are not established by the evidence.",
  "mitigation": "Prevent untrusted remote data from reaching RapidJSON regex parsing paths, and isolate services that must handle such data. No fixed release is identified in the evidence; monitor upstream and update to a maintained release containing a correction when one is available.",
