CVE-2026-73542 Aug 20, 05:16 MEDIUM This Month

Revoked root certificates embedded in multiple Seiko Epson printers and scanners expose device communications to interception via man-in-the-middle attacks. Affected products continue to trust certificates that have been revoked, violating the chain-of-trust model defined by CWE-296, and allowing a suitably positioned attacker to decrypt or read transmitted data. No active exploitation has been confirmed (no CISA KEV listing), and the high attack complexity required for network positioning limits real-world exposure, but confidentiality of printer/scanner communications - potentially including scanned document content - is at risk.

CVE-2026-24066 Jun 10, 12:16 HIGH This Week

Local privilege escalation in Slate Digital Connect 1.37.0 for macOS allows unprivileged users to execute commands as root by connecting to the privileged XPC helper service with a self-signed certificate whose subject OU matches the expected value. The flaw stems from improper certificate validation (CWE-296) in the helper's client authorization logic, which fails to verify the certificate chains to a trusted code-signing authority. No public exploit is identified in CISA KEV at time of analysis, and EPSS reflects very low (0.01%) near-term exploitation probability, but a detailed vendor-lab advisory is publicly available.

CVE-2026-44852 May 12, 18:55 HIGH This Week

Arbitrary file overwrite leading to remote code execution affects HPE Aruba Networking Wireless Operating System (AOS-8 and AOS-10) via the web-based management interface. An authenticated attacker with high privileges can abuse improper input validation in the certificate download function's file path parameter to overwrite arbitrary files and ultimately execute commands as a privileged OS user. There is no public exploit identified at time of analysis, EPSS is low (0.10%, 27th percentile), and CISA SSVC records no known exploitation.

CVE-2026-33779 Apr 09, 21:30 HIGH PATCH This Week

Certificate chain validation bypass in Juniper Junos OS J-Web on SRX Series enables person-in-the-middle attackers to intercept Security Director cloud communications, exposing credentials and sensitive data. All SRX devices connecting to SD cloud fail to properly verify server certificates, allowing interception of authentication material and configuration data. Affects Junos OS versions across all branches prior to 22.4R3-S9, 23.2R2-S6, 23.4R2-S7, 24.2R2-S3, 24.4R2-S2, and 25.2R1-S2/25.2R2. No public exploit identified at time of analysis. Network-positioned attacker with high complexity required (CVSS AC:H).
