Wasmtime's wasmtime-wasi crate 48.0.0 before 48.0.8, 49.0.0 before 49.0.5, and 50.0.0 before 50.0.1 contains a time-of-check/time-of-use race in the wasip3 wasi:sockets udp-socket host implementation that lets guests bypass socket_addr_check send restrictions. A malicious guest can race udp-socket.send against udp-socket.connect to deliver attacker-controlled datagrams to addresses the policy permits only for receiving.

CVE-2026-1280882.2 BAI—
———russh is a Rust SSH client and server library that includes an SSH agent protocol implementation. Prior to version 0.65.1, try_sign() captures an Arc<PrivateKey> before awaiting Agent::confirm() and does not revalidate the shared lock state or key presence after the await. This is a distinct residual defect in the remediation for CVE-2026-116794. A peer, including a remote SSH server using agent forwarding, can begin a confirmation-constrained signature request while the agent is unlocked and receive the signature after another connection locks the agent if the stale confirmation returns true. New post-lock requests are rejected and private key material is not disclosed, but the pending operation bypasses the current lock state. This issue is fixed in version 0.65.1.6hCVE-2026-128079——
———envd provides reproducible development environments for humans and agents. In versions starting with 0.3.38 and before 1.3.6, insufficient containment of host-side requirements-file reads in install.python_packages(requirements=...) could allow access to files outside the build context. An attacker able to influence build input could cause file contents interpreted as dependency entries to appear in debug logs or build-step metadata, subject to the envd process’s permissions. Exploitation in version 1.3.5 additionally requires concurrent modification of relevant filesystem paths. This issue is fixed in version 1.3.6.7hCVE-2026-1290925.7 MÉD—
———CCC Attestation SIG attested-tls-poc through commit 731ca82 contains a time-of-check time-of-use vulnerability because Evidence is appraised only once during the TLS handshake, without post-handshake re-attestation. Attackers with local access to the attesting endpoint can alter workload code, data, configuration, or attached devices like GPUs while peers keep trusting the original Evidence.10hCVE-2026-955187.0 ALT—
———Time-of-check time-of-use (TOCTOU) race condition vulnerability in TÜBİTAK BİLGEM Yazılım Teknolojileri Araştırma Enstitüsü Pardus Package Installer allows Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions.
This issue affects Pardus Package Installer: from 0.7.0 before 0.7.1.10hCVE-2026-1269378.1 ALT—
——0Zipline before 4.6.5 contains a TOCTOU race condition in the POST /api/setup endpoint that allows unauthenticated attackers to create multiple SUPERADMIN accounts by racing concurrent requests before the firstSetup flag is reset. Attackers can send simultaneous requests with spoofed X-Forwarded-For headers during the argon2 hashing window to gain full administrative control of the instance.9hCVE-2026-1269365.9 MÉD—
——0Zipline before 4.7.0 contains a race condition vulnerability that allows users to bypass invitation usage limits, upload storage quotas, and shortened-URL quotas through concurrent requests. Attackers can send overlapping registration, upload, or URL creation requests that pass checks against stale state, creating extra accounts and exceeding administrator-configured resource quotas.15h
