🔒 An authentication bypass in SmarterTools SmarterMail allows unauthenticated actors to reset system administrator passwords via the publicly exposed 'force-reset-password' API endpoint. The endpoint accepts attacker-controlled JSON and an IsSysAdmin flag that, when set to true, triggers admin password reset logic without verifying the old password. watchTowr reported the issue on January 8 and SmarterMail released Build 9511 on January 15; researchers observed exploitation within days. Administrators should apply the update immediately to prevent full account takeover.

🔒 Fortinet issued an advisory describing two FortiCloud SSO bypass vulnerabilities (CVE-2025-59718 and CVE-2025-59719) discovered during an internal code audit. The flaws allowed crafted SAML assertions to bypass authentication on FortiOS, FortiWeb, FortiProxy, and FortiSwitch Manager when FortiCloud SSO was enabled. Recent reports show active exploitation, including instances against fully patched devices, indicating a new attack path. Fortinet advises monitoring IOCs, restricting administrative access, disabling FortiCloud SSO as a workaround, and treating affected systems as compromised.

🔒 A critical authentication vulnerability (CVE-2026-22794) in the Appsmith low-code platform allowed attackers to manipulate password reset links by supplying a malicious HTTP Origin header, causing reset tokens to be redirected to attacker-controlled infrastructure. Exploitation can lead to full account takeover, including administrator access. The flaw affects Appsmith 1.92 and earlier and was corrected in 1.93; internet scans identified 1,666 publicly accessible instances.

🔍 VulnCheck’s State of Exploitation 2026 report finds 28.96% of known exploited vulnerabilities (KEVs) were exploited before or on the day they were disclosed, up from 23.6% in 2024. In 2025 the firm observed exploitation of 884 vulnerabilities — a 15% year‑over‑year increase — across hundreds of vendors and products. Network edge devices (191 KEVs), content management systems (163) and open source software (129) were the most targeted, while operating systems saw the highest share of zero‑day and one‑day exploits. The report also notes time‑to‑exploitation patterns remained consistent and that ransomware attribution often lagged initial exploit disclosures.

⚠️ Cisco has released patches for a critical remote code execution vulnerability, CVE-2026-20045, affecting Unified Communications Manager, Unity Connection, and Webex Calling Dedicated Instance. The flaw allows unauthenticated remote attackers to gain user access via crafted HTTP requests and then escalate privileges to root without user interaction. No workarounds exist; fixes are version-specific and organizations should apply the matching patch or migrate unsupported 12.5 systems.

⚠️ CISA has added four vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog after observing evidence of active exploitation.

CISA urges organizations to prioritize remediation and follow BOD 22-01 guidance to reduce exposure to active threats.

🚨 Cybersecurity firm Arctic Wolf reports automated attacks against Fortinet FortiGate devices that exploit the FortiCloud SSO feature to create rogue admin accounts and rapidly export firewall configurations. The campaign began January 15 and mirrors December exploitation tied to CVE-2025-59718. Observed indicators include SSO logins from cloud-init@mail.io and IP 104.28.244.114. Administrators are advised to disable FortiCloud SSO until Fortinet issues a complete fix.

🔒 Researchers report an authentication bypass in SmarterTools SmarterMail (tracked as WT-2026-0001) being actively exploited days after a Jan 15, 2026 patch (Build 9511). An unauthenticated HTTP request to the /api/v1/auth/force-reset-password endpoint can set an IsSysAdmin flag and reset any administrator password if the attacker knows the admin username. The same privileged path enables SYSTEM-level remote code execution via the product's Volume Mount Command feature. watchTowr Labs went public after community reports showed the endpoint was used to change an admin password on Jan 17, indicating rapid patch reversal by attackers.

🔒 Arctic Wolf warns of a new cluster of automated malicious activity that began on January 15, 2026, involving unauthorized configuration changes to Fortinet FortiGate devices. Attackers exploited SAML-related weaknesses (CVE-2025-59718, CVE-2025-59719) to bypass FortiCloud SSO, create generic admin accounts such as cloud-init@mail.io and names like secadmin or itadmin, and export firewall configurations to external IPs. Administrators are advised to disable the admin-forticloud-sso-login setting until mitigations are confirmed.

🔒 Cisco released patches for a critical, actively exploited vulnerability tracked as CVE-2026-20045 that affects multiple Unified Communications products and Webex Calling Dedicated Instance.

Cisco urged customers to upgrade to fixed releases or apply published patch files; there are no workarounds. The U.S. CISA has added the issue to its KEV catalog with a remediation deadline of February 11, 2026.

🔒 Cisco released patches to address a critical remote code execution vulnerability, CVE-2026-20045, actively exploited against Unified Communications Manager, Unity Connection, and Webex Calling Dedicated Instance. The flaw stems from improper validation of user-supplied input in HTTP requests to the web management interface and can allow an attacker to gain user access and escalate to root. Administrators should apply the version-specific updates or provided .cop patch files immediately, as Cisco reports no available workarounds.

🚨Fortinet customers report attackers bypassing a previously patched FortiGate authentication flaw (CVE-2025-59718) to create admin accounts on devices running FortiOS 7.4.9 and 7.4.10. Fortinet reportedly plans releases of FortiOS 7.4.11, 7.6.6 and 8.0.0 to fully remediate the issue. Until those updates are available, admins are advised to disable FortiCloud SSO using the GUI or the CLI mitigation steps Fortinet published. Shadowserver found over 25,000 devices with FortiCloud SSO enabled in mid-December, and CISA has listed the vulnerability as actively exploited and ordered expedited patching.

🔒 At Pwn2Own Automotive 2026 in Tokyo, researchers chained 37 zero-day vulnerabilities and collected $516,500 in cash awards on the first day.
