Security Bulletin: Qiskit SDK is vulnerable when deserializing QPY Files and may overflow the available stack space.

Summary A maliciously constructed QPY payload that contains specifically constructed ParameterExpression objects as part of the payload can trigger a segfault in the evaluation of those expressions during deserialization. The function qiskit.qpy.load may recurse too deeply and overflow the...

TOON: Prototype pollution when decoding untrusted TOON input

Summary Decoding attacker-controlled TOON containing a proto, constructor, or prototype key wrote through the object's prototype chain instead of creating an own property, polluting Object.prototype for the whole runtime. The expandPaths: 'safe' path dotted keys such as a.proto.x was the stronges...

CVE-2026-19032

A flaw was found in jackson-databind. When deserializing java.nio.file.Path from untrusted JSON input, the deserializer resolves an attacker-supplied Uniform Resource Identifier URI without restricting the URI scheme. This allows a remote attacker to select and drive an arbitrary registered...

Improper Security Control Configuration

NLTK is vulnerable to improper security control configuration. The vulnerability is due to ENFORCE=False being enabled by default in pathsec.py, which causes security validation functions to issue warnings instead of exceptions, allowing an attacker to bypass path traversal and pickle...
