The US Cybersecurity and Infrastructure Security Agency has added two actively exploited vulnerabilities to its Known Exploited Vulnerabilities catalog. CVE-2026-16812 affects the on-premises version of Arista VeloCloud Orchestrator and allows OS command injection that can lead to data leakage, tampering, and denial of service. The flaw carries a maximum CVSS v3.1 base score of 10.0 and is rated Critical. CVE-2025-68686 impacts Fortinet FortiOS and can be used to bypass specific patches and steal sensitive information when combined with another vulnerability that grants prior filesystem access. Federal agencies must remediate the VeloCloud issue by July 30 and the FortiOS issue by August 10.
Why Deep Packet Inspection Overestimates Its Reach in Encrypted Networks
Modern encryption has fundamentally limited the effectiveness of Deep Packet Inspection systems, leaving network monitors with only metadata and behavioral patterns rather than actual content. DPI tools can still classify traffic types and apply policies based on visible flow characteristics, but they cannot read messages, files, or credentials inside properly encrypted sessions without explicit TLS inspection. The article details how TLS 1.3, Encrypted Client Hello, and QUIC further reduce passive visibility while corporate inspection remains possible only when endpoint devices trust an organizational certificate. Russian regulatory requirements around TSPU systems are discussed separately from corporate DPI use, with emphasis on the need for technical confirmation rather than assumptions. The piece also clarifies distinctions between DPI, IDS, IPS, and DLP, and explains why machine learning cannot convert metadata into decrypted payloads. Overall, the analysis shows that DPI remains useful for traffic management and known-threat detection where visibility exists, but it cannot serve as a complete security foundation.
CISA Adds Three Exploited Vulnerabilities in FortiSandbox and SharePoint to KEV Catalog
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added three actively exploited vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog on July 16, 2026. Two of the flaws affect Fortinet’s FortiSandbox malware analysis product and involve OS command injection issues that can be triggered via specially crafted HTTP requests without requiring authentication. The third vulnerability impacts Microsoft SharePoint and stems from unsafe deserialization of untrusted data, potentially allowing remote code execution over the network. CISA’s action follows public advisories released by the vendors in April and June 2026. The agency is urging organizations to apply available patches and mitigations immediately to reduce the risk of compromise.
