CVE-2026-49783 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-2026-54431 MEDIUM PATCH This Month

DPoP (Demonstrating Proof-of-Possession) proof verification in OpenIDC's liboauth2 C library incorrectly accepts malformed proofs that embed private Elliptic Curve (EC) key material in the JWK header, directly violating RFC 9449 §4.3 step 7. The `oauth2_token_verify()` function returns success instead of rejecting such proofs, subverting DPoP's core token-binding security guarantee and enabling information disclosure of private key material. No active exploitation is confirmed (not in CISA KEV), no public exploit code has been identified, and a patch is available in liboauth2 2.3.0.

CVE-2026-14440 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 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 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-2026-11127 MEDIUM PATCH This Month

Domain spoofing via crafted WebAPK in Google Chrome on Android prior to 149.0.7827.53 enables remote unauthenticated attackers to deceive users about the web origin of installed Progressive Web Apps, with high integrity impact as confirmed by the CVSS I:H rating. The CVSS vector (AV:N/AC:L/PR:N/UI:R) confirms the attack is network-accessible and requires no privileges, though user interaction is a necessary precondition. No public exploits have been identified and EPSS sits at 0.03% (10th percentile), indicating minimal observed exploitation pressure; however, the trust-abuse potential for phishing campaigns makes timely patching advisable.

Universal Cross-Site Scripting (UXSS) in Google Chrome's Keyboard implementation prior to version 149.0.7827.53 enables remote unauthenticated attackers to inject arbitrary scripts or HTML across origin boundaries via a crafted HTML page. The Scope:Changed CVSS vector reflects the fundamental nature of this class: successful exploitation bypasses the Same-Origin Policy, potentially granting script access to sessions, cookies, and DOM content across all origins open in the browser. No public exploit has been identified at time of analysis, and the EPSS score of 0.06% (18th percentile) indicates low current exploitation probability, though UXSS primitives are historically high-value for targeted attacks.

Gatekeeper security checks in macOS Tahoe can be bypassed using maliciously crafted ZIP archives due to a logic flaw in file handling. An attacker can create a weaponized ZIP file that, when extracted or opened by a user, circumvents Gatekeeper validation, potentially allowing execution of untrusted code. The vulnerability requires user interaction (opening or extracting the malicious archive) and is limited to local attack surface. Vendor-released patch: macOS Tahoe 26.5.
