Improper state management in MongoDB libmongocrypt can cause provider-specific data to be treated as an incompatible type when cleaning up a key document containing duplicate masterKey fields. An authenticated actor who can modify key vault documents, or a server that returns such a key document, can cause invalid memory access and invalid frees in the client process. This can terminate the application or corrupt process memory.

CVE-2026-1126598.8 HIG—
———A type confusion issue was addressed with improved memory handling. This issue is fixed in Safari 27.2, iOS 26.7.2 and iPadOS 26.7.2, iOS 27.2 and iPadOS 27.2, macOS Golden Gate 27.2, visionOS 27.2. Processing maliciously crafted web content may lead to arbitrary code execution.3hCVE-2026-1163706.3 MED—
———A security flaw has been discovered in 2K Games Sid Meier's Civilization IV 1.0.12.68. The affected element is the function loadstring of the component Lua sandbox. Performing a manipulation results in type confusion. The attack may be initiated remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure.7hCVE-2026-1164897.5 HIG—
———Timescale pgvectorscale before 0.9.1 contains a type confusion vulnerability that allows low-privileged database users to corrupt memory by shadowing pgvector's vector type or operators. Attackers with CREATE privilege on the vectorscale schema can pre-create shadow objects, then build and query DiskANN indexes over crafted values to cause out-of-bounds reads and writes, disclosing memory, crashing the server, or escalating privileges.7hCVE-2026-1161116.3 MED—
——0A vulnerability was determined in 2K Games Civilization V 1.0.3.144. Impacted is the function loadstring of the component Lua Sandbox. Executing a manipulation can lead to type confusion. The attack may be performed from remote. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.8hCVE-2026-115892—37.4%
——11Wasmtime is a runtime for WebAssembly. From 46.0.0 until 48.0.7 and 49.0.4, lowering a host-created component-model stream or future into a guest can omit a required payload-type check after the value passes through guest code and returns through StreamAny, FutureAny, Val::Stream, Val::Future, or an equivalent typed reader. A malicious guest that controls exported function types or returned values can cause the host to pass the type-erased value to a guest expecting a different payload type, which panics the Wasmtime host. This issue is fixed in versions 48.0.7 and 49.0.4.3dCVE-2026-1158899.9 CRI39.1%
——12Wasmtime is a runtime for WebAssembly. Prior to 36.0.19 and 43.0.0, the Cranelift compiler backend bit-packs SSA value indices in a way that can silently overflow in release builds when compiling a sufficiently large or specially crafted Wasm function with many SSA values. The overflow can make Cranelift reference incorrect IR values, causing arbitrary miscompilation, type confusion, and other attacker-controlled effects that may escape the Wasm sandbox on any architecture using the default Cranelift backend. This issue is fixed in versions 36.0.19 and 43.0.0.7h
