A third-party marketing vendor, Klue, experienced unauthorized access to its integration layer, which connects to other SaaS platforms like Salesforce, leading to the compromise of an OAuth token and subsequent unauthorized access to Recorded Future's Salesforce account, where business data fields including customer contact names, email addresses, and potentially business contract information were accessed.

An unauthenticated attacker can exploit a cross-site scripting (XSS) vulnerability (CVE-2026-44752) in SAP NetWeaver Application Server Java by injecting malicious JavaScript through crafted URLs, leading to client-side script execution, access to sensitive session information, and modification of non-sensitive data, resulting in high confidentiality impact and low integrity impact.

An unauthenticated attacker can exploit CVE-2026-0487, a vulnerability in SAProuter running on Microsoft Windows, by loading malicious DLL files from an untrusted location, allowing them to execute arbitrary code on the affected system with high impact on confidentiality, integrity, and availability.

An HTTP Request Smuggling vulnerability (CVE-2026-27690, CWE-444) in SAP Approuter allows an unauthenticated attacker to send a specially crafted HTTP request leading to request-response desynchronization, which can result in the exposure of user responses and cause a denial of service by making the system unavailable.

A critical vulnerability, CVE-2026-52827, in Kimai versions prior to 2.59.0 allows an attacker who has compromised a user's password to bypass Two-Factor Authentication (TOTP) for the REST API by intercepting and replaying the `KIMAI_SESSION` cookie obtained after password verification but before TOTP completion, granting full authenticated API access.

A critical vulnerability, CVE-2026-52824, in the official Kimai Docker image allows unauthenticated attackers to forge authentication tokens and achieve account takeover, including super_admin accounts, due to the image shipping with a default, publicly known APP_SECRET environment variable used by Symfony to HMAC-sign session cookies and login links.

An unbounded CPU Denial-of-Service vulnerability exists in the `json_repair` library's `SchemaRepairer.resolve_schema()` function, allowing an unauthenticated attacker to provide a specially crafted JSON schema containing a circular `$ref` pointer, leading to indefinite CPU consumption and service unavailability.

An authentication bypass vulnerability (CVE-2026-47677) in FacturaScripts' `/login?action=two-factor-validation` endpoint allows unauthenticated attackers to conduct a brute-force attack against Time-based One-Time Passwords (TOTP) for any 2FA-enabled user, including administrators, due to the absence of password verification, CSRF protection, and rate-limiting, leading to complete account takeover with high confidentiality and integrity impact, as well as potential denial of service via account lockout.

A path traversal vulnerability (CVE-2026-57856) exists in the Bucket file storage API of Cockpit CMS, allowing authenticated low-privileged users to exploit a flaw in bucket name sanitization to access, upload, or delete files across all buckets by using crafted '..' sequences.

A missing authorization vulnerability, CVE-2026-57855, in the Cockpit CMS Bucket file storage API allows any authenticated user, regardless of their assigned role, to perform all file operations on any named bucket, including those designated for administrative use, potentially leading to privilege escalation, data manipulation, or data destruction.

The U.S. Treasury Department sanctioned First VPN Service (1VPNS) and its administrator, Dmytro Rashevskyi, for facilitating ransomware attacks by providing anonymity and evasion capabilities to cybercriminals, and also sanctioned Yegeniy Vladimirovich Silayev for selling 'cryptors' that make malware harder to detect, impacting critical infrastructure.

ShinyHunters, and related threat actor Storm-3138, conducted campaigns between mid-2025 and mid-2026 by employing voice phishing, supply chain compromise, and misconfigured guest access to abuse trusted OAuth relationships in SaaS applications like Salesforce, leading to unauthorized access, data exfiltration, and persistence.

Since late June 2026, an unattributed threat actor has launched a campaign leveraging over 290 deceptive GitHub repositories that impersonate legitimate software and security vendors, including Arctic Wolf, to deliver the BoryptGrab-Lineage infostealer through concealed download links, compromising victim systems upon execution.

A critical server-side request forgery (SSRF) vulnerability, CVE-2026-62240, exists in the `validate_url` function of CrewAI versions prior to 1.15.1, allowing attackers to bypass security filters using URL redirects or DNS rebinding to access internal services and cloud metadata endpoints.
