Step CA affected by an index out of bounds panic in TPM attestation EKU validation

Summary An attacker can trigger an index out-of-bounds panic in Step CA by sending a crafted attestation key AK certificate with an empty Extended Key Usage EKU extension during TPM device attestation. Details When processing a device-attest-01 ACME challenge using TPM attestation, Step CA...

CVE-2026-34943

A flaw was found in Wasmtime, a runtime for WebAssembly. A malicious guest can exploit an issue where a flags-typed component model value, containing unexpected bit settings, causes the host system to panic during processing. This vulnerability can lead to a Denial of Service DoS, rendering the...

CVE-2026-35645

OpenClaw is affected by a privilege escalation vulnerability in the gateway plugin subagent fallback deleteSession function, which uses a synthetic operator.admin runtime scope.

nodejs: v8: Node.js: Denial of Service via V8 string hashing mechanism due to predictable hash collisions

A flaw was found in V8's string hashing mechanism within Node.js. A remote attacker can exploit this vulnerability by crafting requests containing integer-like strings. These specially crafted strings cause predictable hash collisions in V8's internal string table, particularly when processed by...

DEBIAN-CVE-2026-35195

Wasmtime is a runtime for WebAssembly. Prior to 24.0.7, 36.0.7, 42.0.2, and 43.0.1, Wasmtime's implementation of transcoding strings between components contains a bug where the return value of a guest component's realloc is not validated before the host attempts to write through the pointer. This...

CVE-2026-34983

Wasmtime is a runtime for WebAssembly. In 43.0.0, cloning a wasmtime::Linker is unsound and can result in use-after-free bugs. This bug is not controllable by guest Wasm programs. It can only be triggered by a specific sequence of embedder API calls made by the host. Specifically, the following...

CVE-2026-34943

Wasmtime is a runtime for WebAssembly. Prior to 24.0.7, 36.0.7, 42.0.2, and 43.0.1, Wasmtime contains a possible panic which can happen when a flags-typed component model value is lifted with the Val type. If bits are set outside of the set of flags the component model specifies that these bits...
