CVE-2026-13577

Dancer2 versions through 2.1.0 for Perl generate insecure session ids when required CSPRNG modules are unavailable. Dancer2::Core::Role::SessionFactory::generateid silently falls back to a built-in rand-derived session id unless both Math::Random::ISAAC::XS and Crypt::URandom are available. The...

CVE-2026-13577

The CVE-2026-13577 entry affects Dancer2 for Perl up to version 2.1.0. When secure PRNG sources (Math::Random::ISAAC::XS, Crypt::URandom) are unavailable, Dancer2::Core::Role::SessionFactory::generate_id falls back to a low-entropy, rand-derived session id. The fallback is computed from a SHA-1 h...

CVE-2026-11403

The CVE affects Sonatype Nexus Repository Manager. The flaw is in the format-specific API key generation, where a remote attacker could gain unauthorized access to repository operations as a targeted user if a format-specific API key realm (NuGet API Key, Docker Bearer Token, or npm Bearer Token)...

USN-8524-1: Python vulnerability

It was discovered that Python did not use sufficient entropy for Expat hash-flooding protection in the xml.parsers.expat and xml.etree.ElementTree modules. An attacker could use this to cause a denial of service via a crafted XML document...

USN-8520-1: Expat vulnerability

It was discovered that Expat used insufficient entropy when generating hash salt values for its internal hash table. An attacker could use this to craft an XML document that triggers hash flooding, leading to a denial of service...
