Improper Output Handling

Apache Log4j is vulnerable to Improper Output Handling. The vulnerability is due to JsonTemplateLayout generating invalid JSON when processing non-finite floating-point values e.g., NaN, Infinity, which are not compliant with RFC 8259, allowing attacker-controlled data in log events to produce...

SUSE CVE-2026-39395

Cosign provides code signing and transparency for containers and binaries. Prior to 3.0.6 and 2.6.3, cosign verify-blob-attestation may erroneously report a "Verified OK" result for attestations with malformed payloads or mismatched predicate types. For old-format bundles and detached signatures,...

CVE-2026-40198 Net::CIDR::Lite versions before 0.23 for Perl does not validate IPv6 group count, which may allow IP ACL bypass

Net::CIDR::Lite versions before 0.23 for Perl does not validate IPv6 group count, which may allow IP ACL bypass. packipv6 does not check that uncompressed IPv6 addresses without :: have exactly 8 hex groups. Inputs like "abcd", "1:2:3", or "1:2:3:4:5:6:7" are accepted and produce packed values of...
