  "title": "Out-of-bounds write in XS::libbrotli's bundled Brotli decoder",
  "summary": "XS::libbrotli versions before 1.2.1.0 include a vulnerable bundled Brotli decoder that can also affect dependent XS modules built against it. An attacker who can provide Brotli-compressed untrusted input to such a module may cause memory disclosure, a process crash, or potentially code execution.",
  "mitigation": "Upgrade XS::libbrotli to version 1.2.1.0 or later, then rebuild dependent XS modules so they link the updated bundled decoder. Do not rely solely on an operating system Brotli update.",
