Improper Certificate Validation

Overview Affected versions of this package are vulnerable to Improper Certificate Validation in the processing of X.509 certificate paths with DNS name constraints when the end-entity certificate lacks a subject alternative name. An attacker can circumvent DNS name constraints by using a mixed-ca...

CVE-2026-32884 Botan: Case-Insensitive CN Values Bypass DNS excludedSubtrees Name Constraints (RFC 5280 Violation)

Botan is a C++ cryptography library. Prior to version 3.11.0, during processing of an X.509 certificate path using name constraints which restrict the set of allowable DNS names, if no subject alternative name is defined in the end-entity certificate Botan would check that the CN was allowed by t...

Server-side Request Forgery (SSRF)

Overview Affected versions of this package are vulnerable to Server-side Request Forgery SSRF through improper handling of case-insensitive URL schemes in the FilterDeadline function. An attacker can access arbitrary files within the container by submitting URLs with mixed-case or uppercase schem...
