  "title": "botan3: Botan is a C\u002B\u002B cryptography library",
  "description": "Botan is a C\u002B\u002B cryptography library. From 1.11.22 until 3.13.0, Botan\u0027s Python binding converted Python strings containing U\u002B0000 to const char* values without consistently rejecting the embedded NUL, causing bcrypt and check_bcrypt to process only the prefix before the NUL. Applications could validate a longer password but hash a shorter effective value, allowing application password-policy bypass; scrypt and argon2 are unaffected. This issue is fixed in version 3.13.0.",
