CVE-2026-70174 Oct 13, 19:19 NuGet HIGH PATCH GHSA Exploit Unlikely This Week

Remote code execution in the Windows Presentation Foundation (WPF) component of Microsoft .NET and .NET Framework allows an unauthorized remote attacker to run arbitrary code after a victim interacts with a crafted XPS document. The flaw is an improperly implemented security check for URI handling (CWE-358): WPF's XPS hyperlink navigation can bypass its URI restrictions and reach an attacker-controlled ObjectDataProvider, resulting in code execution in the context of the hosting application. Affected runtimes include .NET 8 before 8.0.32, .NET 9 before 9.0.21, .NET 10 before 10.0.13, .NET 11 before 11.0.0-rc.2, multiple .NET Framework 3.5/4.6.2/4.7.x/4.8/4.8.1 builds, and Visual Studio 2022 17.14 before 17.14.42 and Visual Studio 2026 18.10 before 18.10.4; vendor patches are available and there is no public exploit identified at time of analysis, with exploitation gated by mandatory user interaction (UI:R) and SSVC Automatable set to no.

CVE-2026-49783 Jul 14, 17:05 HIGH PATCH Exploit Unlikely This Week

Security feature bypass in Windows Secure Boot (CWE-358) allows a locally authenticated attacker on affected Windows 10, Windows 11, and Windows Server (2016 through 2025) systems to defeat the boot-integrity trust chain due to an improperly implemented standard security check. Because Secure Boot is the gate that blocks unsigned/tampered bootloaders and rootkits, a successful bypass can enable pre-OS persistence and undermine downstream protections such as BitLocker and Measured Boot. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV; Microsoft has published a patch via its update guide.

CVE-2026-14440 Jul 01, 22:35 HIGH This Week

TLS certificate misissuance affecting Cloudflare Universal SSL zones lets an attacker who controls an ACME account at a CA in the auto-managed CAA RRset obtain a browser-trusted certificate for a victim domain, because Cloudflare's authoritative DNS serves a permissive auto-managed CAA RRset that supersedes customer-set records and drops RFC 8657 accounturi/validationmethods bindings. The result is a bypass of account-binding and validation-method-binding protections end-to-end, enabling MITM against the affected domain. Reported by Cloudflare (researcher David Osipov) with no public exploit identified at time of analysis; CVSS 4.0 base score is 7.6 with high attack complexity and a present attack requirement.

CVE-2026-12577 Jul 01, 07:05 HIGH This Week

Denial-of-service exposure in the Delta Electronics DVP80ES3 programmable logic controller (part of the DVP-ES3 series) stems from an improperly implemented standard security check (CWE-358) that a remote, unauthenticated attacker can abuse over the network to force a loss of availability. The CVSS 4.0 base score is 8.7 (High), driven entirely by high availability impact with no confidentiality or integrity impact in the scored vector. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; note that the vendor's tags label this 'Information Disclosure,' which conflicts with the availability-only CVSS vector and should be verified against the Delta advisory.

CVE-2026-48797 Jun 17, 13:20 LIB CRITICAL PATCH GHSA Act Now

Authentication bypass in Backpropagate 1.1.0 and 1.1.1 lets any client that can reach the Reflex web UI's bound port take full control of the training control plane, despite the operator passing --auth user:pass. The CLI advertised and confirmed authentication as active, but the Reflex backend never read the BACKPROPAGATE_UI_AUTH variable and registered no middleware, so dataset upload, training control, GGUF export, and HuggingFace Hub push were exposed unauthenticated. No public exploit identified at time of analysis, but the gap is trivially reachable and CVSS 4.0 is 9.3.

CVE-2026-44473 May 11, 15:18 Go HIGH PATCH GHSA This Week

User equipment (UE) downlink traffic can be redirected to attacker-controlled radios in Ella Core (5G AMF software) versions prior to 1.10.0. A malicious radio with a valid NG Setup connection can forge PDUSessionResourceSetupResponse messages using arbitrary AMF-UE-NGAP-IDs, causing Ella Core to create GTP tunnels that misdirect victim UE downlink packets to the attacker's radio. This enables traffic interception and denial of service against targeted UEs. The vulnerability stems from missing validation that NGAP messages arrive on the correct SCTP association for the UE context. No public exploit identified at time of analysis, and EPSS data not available. Vendor-released patch: version 1.10.0.

Free5GC Access and Mobility Management Function (AMF) v4.2.1 and earlier fails to verify UE Security Capabilities in NGAP PathSwitchRequest messages, allowing a malicious gNB to overwrite the AMF's stored security algorithm preferences with arbitrary values. These corrupted capabilities are then propagated in PathSwitchRequestAcknowledge and subsequent HandoverRequest messages, causing all inter-gNB handovers for affected UEs to fail due to algorithm mismatches. This results in persistent handover denial-of-service until UE re-registration. The vulnerability is directly contrary to 3GPP TS 33.501 §6.7.3.1 verification requirements and has been demonstrated with a public proof-of-concept using Free5GC v4.2.1 and UERANSIM.

Keycloak's JWT authorization grant flow fails to verify that an Identity Provider is enabled before accepting tokens signed by its key, allowing attackers with a disabled IdP's signing credentials to obtain valid access tokens. This authentication bypass affects organizations that have disabled IdPs due to compromise or offboarding but retain the associated signing keys. An attacker can exploit this to gain unauthorized access to systems relying on Keycloak for authentication.

CVE-2026-96303 Oct 13, 19:21 MEDIUM PATCH Exploit Unlikely This Month

Security feature bypass in Microsoft PowerShell 7.x allows an attacker to defeat a built-in protective control in the affected runtime, with the integrity impact scored as high while confidentiality and availability are unaffected. The flaw affects PowerShell 7.4 before 7.4.21, 7.5 before 7.5.12, and 7.6 before 7.6.7, and exploitation requires a victim to interact with attacker-supplied content (CVSS UI:R), so it cannot be triggered silently or server-side without a human running the malicious input; no authentication or prior privileges are needed. No public exploit code or active exploitation has been identified at time of analysis (CISA SSVC records Exploitation: none), and a vendor patch is available, making this a moderate rather than high-urgency issue. Note that the vendor description does not name the specific security feature being bypassed, which limits defenders' ability to scope the issue to a particular configuration or execution mode.

Security feature bypass in Windows PowerShell allows an unauthenticated attacker to defeat a security check, but the victim must actively run or open attacker-supplied content (UI:R), so it is not a hands-off remote exploit. Impact is integrity-only (C:N/I:H/A:N, CVSS 6.5); Microsoft has released patches, CISA SSVC rates exploitation as none and automatable as no, and no public exploit code was identified at time of analysis.
