CISA adds SharePoint RCE CVE-2026-45659 to KEV

Send us Fan Mail [https://www.buzzsprout.com/2602483/fan_mail/new] A critical SharePoint vulnerability is now under active exploitation, while regulators are making it clear that inaccurate security claims can carry legal consequences. At the same time, attackers are turning edge device flaws into repeatable ransomware entry points, and major platforms are reshaping how security intelligence is delivered. This episode breaks down what these shifts mean in practice. From emergency patching decisions to the growing legal weight of compliance frameworks, the environment is changing from both sides. Security leaders are being pushed to move faster operationally while also proving that controls are actually in place. We also cover FortiBleed's role in ransomware campaigns, Visa's move into threat intelligence, and what it signals about the merging of fraud and cybersecurity.

Tomcat auth bypass breaks security-constraint protections

Send us Fan Mail [https://www.buzzsprout.com/2602483/fan_mail/new] Authentication controls failing silently is a different kind of risk. Today's episode breaks down how newly disclosed Apache Tomcat vulnerabilities allowed attackers to bypass protections that teams believed were enforced, and why this changes how you validate access controls. For security and IT leaders, the shift is clear. Configuration is no longer proof of enforcement. You need to test real access paths, verify behavior, and assume gaps exist until proven otherwise. At the same time, active exploitation of an Oracle E-Business Suite flaw shows how quickly attackers move once patches are released, while new federal deadlines on post-quantum cryptography turn long-term planning into near-term operational work. We also cover Zscaler's move into AI agent control planes and what it signals about identity in autonomous systems, along with several other key developments shaping the threat landscape.

EY grads accused of PM bank snooping

Send us Fan Mail [https://www.buzzsprout.com/2602483/fan_mail/new] Today's episode focuses on a quiet but critical failure point: access control. A real-world incident involving contractor access to sensitive financial data shows how authorization gaps, not external attackers, are often the weakest link. For security and IT leaders, this is a shift in where risk lives. Insider misuse, third-party exposure, and inherited liability from vendors are becoming more consequential than perimeter threats. From financial filings to endpoint security, the common thread is clear. If you do not tightly control who can access what, and when, you are carrying unseen risk. We also cover a major IRS liability ruling, active ransomware exploitation of a Windows privilege escalation flaw, and key signals from across the security landscape.

ACSC warns FortiBleed: rotate creds, enforce MFA

Send us Fan Mail [https://www.buzzsprout.com/2602483/fan_mail/new] Credential-based security is breaking in multiple directions at once. Old passwords are being reused to breach networks, unpatched ERP systems are getting exploited in the wild, and attackers are shifting toward token theft that bypasses traditional login defenses entirely. For security and IT leaders, this is a shift from protecting logins to continuously validating identity across sessions, systems, and now AI-driven actors. The common thread is clear: identity is the new control plane, and gaps in credential hygiene, patching, and token visibility are turning into real-world incidents. This episode also covers a major Oracle EBS vulnerability under active exploitation, the rise of device-code phishing attacks targeting Microsoft environments, and new funding aimed at rebuilding IAM for AI agents.

UK banks pilot consent-led reusable digital ID

Send us Fan Mail [https://www.buzzsprout.com/2602483/fan_mail/new] Banks are moving into identity, and that could reshape how authentication and onboarding work across the digital economy. A new UK pilot shows how bank-verified identity attributes may become reusable across services, shifting control away from fragmented KYC systems. For security and IT leaders, this signals a change in where trust lives. Identity may consolidate around institutions that already hold strong signals, while access to advanced AI tools becomes uneven and employee behavior continues to outpace policy. The result is a more fragmented, less controllable environment that requires new approaches to integration, governance, and visibility. This episode also covers OpenAI's restricted GPT-5.6 launch, the rise of shadow AI in the workplace, and a new browser-based surveillance technique using WebRTC.
