CVE-2025-68833 Aug 24, 13:42 MEDIUM This Month

Insufficient access control granularity in HCL Hive's Keycloak IAM instance exposes protected resources to unauthenticated or unauthorized network attackers. The CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates this is remotely exploitable without credentials or user interaction against the IAM layer, resulting in unauthorized read access to confidential resources. No public exploit code or CISA KEV listing has been identified at time of analysis, and a vendor knowledge base article (KB0131731) has been published.

CVE-2026-21751 Aug 24, 13:18 HIGH This Week

HCL Hive employs a risky cryptographic primitive (CWE-1240) that creates systemic trust failure across the platform: if any single internal component is compromised, an attacker can exploit the weak cryptographic construction to achieve unauthorized lateral movement or harvest credentials at scale. The CVSS vector (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N) indicates the flaw is reachable over the network without authentication, though high attack complexity caps opportunistic risk. No public exploit code or active exploitation has been identified at time of analysis.

CVE-2026-50303 Jul 14, 17:06 MEDIUM PATCH Exploit Unlikely This Month

Windows Key Guard on multiple Windows 10, Windows 11, and Windows Server editions exposes a cryptographic security bypass to locally authenticated low-privilege users due to CWE-1240 (Use of a Cryptographic Primitive with a Risky Implementation), allowing protected key material to be accessed in violation of the Key Guard security boundary. Affected builds span Windows 10 1809 through Windows 11 26H1 and Windows Server 2019 through 2025, representing a broad swath of Microsoft's current supported OS surface. No public exploit identified at time of analysis; EPSS sits at 0.21% (11th percentile) and SSVC classifies exploitation status as none with no automation potential, indicating low near-term exploitation probability despite the ubiquitous footprint.

CVE-2026-44410 May 26, 09:39 LOW Monitor

Business logic abuse in ZTE ZXUniPOS NDS-LTE (versions V24.40.40 and V24.30.40CP02) allows a highly privileged authenticated network attacker to manipulate legitimate application functions in ways unintended by the designer, yielding limited integrity and availability degradation. The CVSS score of 3.8 (Low) combined with an EPSS exploitation probability of 0.03% (7th percentile) and SSVC exploitation status of 'none' collectively indicate minimal immediate real-world threat. No public exploit code and no CISA KEV listing have been identified at time of analysis.

CVE-2025-64647 Mar 25, 20:37 MEDIUM PATCH This Month

IBM Concert versions 1.0.0 through 2.2.0 implement cryptographic algorithms that are weaker than expected, allowing attackers to decrypt highly sensitive information without authentication. The vulnerability has a CVSS score of 5.9 with high confidentiality impact but no integrity or availability impact. A patch is available from IBM, and this represents a pure information disclosure risk affecting the confidentiality of encrypted data.

CVE-2026-27017 Feb 20, 03:16 Go MEDIUM PATCH This Month

uTLS versions 1.6.0 through 1.8.0 fail to properly mimic Chrome's cipher suite selection behavior when using GREASE ECH, randomly choosing ChaCha20 for encrypted client hello while consistently using AES for the outer handshake—a mismatch that does not occur in actual Chrome and creates detectable fingerprints. This inconsistency affects users relying on uTLS for fingerprinting resistance and could enable network observers to distinguish uTLS traffic from legitimate Chrome connections. A patch is available to correct the cipher suite selection logic.
