CVE-2026-33524

Summary (CVE-2026-33524): Zserio v2.18.0 and earlier are vulnerable to a Denial of Service via unbounded memory allocations during deserialization caused by an integer overflow in BitStreamReader/Array handling. A crafted payload as small as 4–5 bytes can trigger allocations up to 16 GB, crashing...

CVE-2026-33524 Zserio: Integer Overflow in BitStreamReader and Unbounded Memory Allocation in Deserialization

Zserio is a framework for serializing structured data with a compact and efficient way with low overhead. Prior to 2.18.1, a crafted payload as small as 4-5 bytes can force memory allocations of up to 16 GB, crashing any process with an OOM error Denial of Service. This vulnerability is fixed in...

Improperly Controlled Modification of Dynamically-Determined Object Attributes

Overview Affected versions of this package are vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes via the objecttoexecution.go process. An attacker can execute unauthorized actions or inject malicious content by providing crafted AI-generated YAML that is...

GHSA-RP7V-4384-HFRP k8sGPT has Prompt Injection through its k8sGPT-Operator

Summary In the auto-remediation pipeline, objecttoexecution.go was deserializing the AI-generated YAML directly into a Deployment object, but there was lack of validation from the original Deployment object. Details This issue was fixed after coordination with Alex Jones. PoC To minimize the...

go-zserio has Unbounded Memory Allocation for All Platforms

Impact When deserializing arrays, strings or bytes blob types zserio first reads the size of the variable, and then allocates sufficient memory to load data. Since the size is always trusted this can be abused by creating a data file with a large size value, causing the zserio runtime to allocate...

GHSA-Q339-8RMV-2MHV ERB has an @_init deserialization guard bypass via def_module / def_method / def_class

Summary Ruby 2.7.0 before ERB 2.2.0 was published on rubygems.org introduced an @init instance variable guard in ERBresult and ERBrun to prevent code execution when an ERB object is reconstructed via Marshal.load deserialization. However, three other public methods that also evaluate @src via eva...
