CISA Adds Exploited PTC Windchill RCE Flaw to KEV as Web Shell Attacks Continue

The U.S. Cybersecurity and Infrastructure Security Agency CISA on Thursday added a critical remote code execution vulnerability impacting PTC Windchill PDMlink and PTC FlexPLM enterprise Product Data Management PDM and Product Lifecycle Management PLM software to its Known Exploited Vulnerabiliti...

Server-Side Request Forgery

jackson-databind is vulnerable to server-side request forgery SSRF. The vulnerability is due to eager DNS resolution during InetSocketAddress deserialization, where untrusted hostnames are resolved before application-level validation, allowing attackers to trigger arbitrary DNS requests by...

CVE-2026-40083

A flaw was found in Cacti. This vulnerability, a SQL Injection, allows a remote attacker with SNMP Simple Network Management Protocol agent management permissions to execute arbitrary SQL commands. The flaw occurs due to unsanitized deserialization of user-controlled input in the managers.php fil...

GHSA-QHMF-XW27-6RQR MessagePack-CSharp: Typeless deserialization type restrictions do not recurse into arrays or generic arguments

Summary MessagePack-CSharp's typeless deserialization includes MessagePackSerializerOptions.ThrowIfDeserializingTypeIsDisallowedType as a safety check for dangerous types. The default implementation checks the outer type name, but it does not recursively inspect array element types or generic typ...

GHSA-CXMJ-83GH-FP49 MessagePack-CSharp: Multi-dimensional array formatters allocate from unchecked dimensions

Summary MessagePack-CSharp's multi-dimensional array formatters read dimension lengths directly from the payload and allocate T,, T,,, or T,,, before validating that the dimension product matches the encoded element count. The formatter reads a guarded element array header, but allocation of the...

GHSA-W567-GJR2-HM5J MessagePack-CSharp: Unity unsafe blit formatter allocates from unbounded byte length

Summary UnsafeBlitFormatterBase.Deserialize reads an attacker-controlled byteLength from an extension payload and allocates an array based on that value before validating it against the extension header length or remaining payload bytes. The outer extension header is bounded by available input, b...

GHSA-WFR3-XJ75-PFWH MessagePack-CSharp: DynamicUnionResolver-generated deserializers miss depth enforcement

Summary Runtime-generated union deserializers emitted by DynamicUnionResolver do not call MessagePackSecurity.DepthStepref reader and do not decrement reader.Depth around recursive deserialization and skip paths. This means union deserialization does not consistently participate in the maximum...

GHSA-2X83-8G95-XH59 MessagePack-CSharp: ExpandoObject formatter can perform quadratic insertion work on untrusted maps

Summary ExpandoObjectFormatter.Deserialize populates System.Dynamic.ExpandoObject by calling IDictionary.Add for each map entry. ExpandoObject internally maintains member names in array-like structures, so inserting many distinct keys can require repeated linear scans and array copies. For large...
