  "title": "botan3: Botan is a C\u002B\u002B cryptography library",
  "description": "Botan is a C\u002B\u002B cryptography library. Prior to 3.13.0, Botan\u0027s online OCSP client allowed a single HTTP redirect while posting an OCSP request to the URI in a certificate\u0027s Authority Information Access extension. A malicious OCSP responder or an on-path attacker could redirect the client to make one blind request to an otherwise unreachable internal HTTP service. The primary impact is blind SSRF that might affect internal services with non-idempotent GET handlers, and response timing can provide a coarse internal-service oracle. This issue is fixed in version 3.13.0.",
