Privileged File System Vulnerability Present in a SCADA System
Unit 42 details CVE-2025-0921 (CVSS 6.5), a privileged file operations flaw in Iconics Suite enabling DoS and privilege escalation.
Unit 42 disclosed CVE-2025-0921 (CVSS 6.5), an execution-with-unnecessary-privileges flaw in the Pager Agent of the AlarmWorX64 MMX feature of Mitsubishi Electric Iconics Digital Solutions GENESIS64. Attackers could misuse privileged file system operations to corrupt critical binaries, causing denial-of-service or integrity loss on vulnerable SCADA systems. The analysis demonstrates a chain with CVE-2024-7587, which grants excessive permissions to the C:\ProgramData\ICONICS directory via the GenBroker32 installer. Iconics released an advisory with a workaround that addresses the reported issues.

CVE-2026-84501: Apache ZooKeeper: Operational log forgery via newline injection in EnsembleAuthenticationProvider
Unauthenticated attackers can forge Apache ZooKeeper operational log lines via newline injection in crafted ensemble authentication requests.
CVE-2026-84501 (moderate severity) affects Apache ZooKeeper 3.9.0-3.9.5 and 3.8.0-3.8.6. An unauthenticated attacker can inject arbitrary fake log lines into the operational log by sending a crafted add_auth("ensemble", ...) request containing newline characters. The forged entries could mislead operators or corrupt log-based monitoring and forensics.

CVE-2026-84439: Apache ZooKeeper: Audit log injection via unsanitized output from multiple sources
Apache ZooKeeper audit logs are vulnerable to arbitrary field injection by unauthenticated attackers via tab characters in digest auth requests.
CVE-2026-84439 (important severity) affects Apache ZooKeeper 3.9.0-3.9.5 and 3.8.0-3.8.6 when audit logging is enabled (zookeeper.audit.enable=true). An unauthenticated attacker can inject arbitrary fields into the audit log by sending a digest authentication request with embedded tab characters, undermining audit trail integrity and potentially enabling log-analysis evasion or spoofing.

CVE-2026-87779: Apache Syncope: AES Secret Key disclosure via log output
Apache Syncope's CVE-2026-87779 exposes AES secret keys in log output when keys use non-standard lengths, rated important.
CVE-2026-87779 is an important-severity insertion of sensitive information into log file vulnerability in Apache Syncope. When an AES key of non-standard length (not 16, 24 or 32 bytes) is used, the secret key can be disclosed via log output. Affected versions are syncope-core-spring 3.0.15 through 3.0.16, 4.0.3 through 4.0.7, and 4.1.0-M0 through 4.1.2.

CVE-2026-82434: Apache Storm Nimbus, Apache Storm Client: Disclosure of the Topology ZooKeeper Credential to Read-Only Users and to Logs
Apache Storm Nimbus and Client expose ZooKeeper topology credentials to read-only users and logs, fixed in 3.1.0.
CVE-2026-82434 affects Apache Storm Nimbus (storm-server) and Storm Client (storm-client) versions 3.0.0 before 3.1.0. When ZooKeeper authentication is configured, Storm retains storm.zookeeper.topology.auth.payload in the topology configuration because workers need it, but Nimbus serves that configuration verbatim to callers holding only read-only access. The credential also leaks into logs.

New Passkey Attacks Can Recover Synced Private Keys or Bypass Phishing
Three research teams showed passkey bypasses: WebAuthn assertion replay in Microsoft Entra ID, synced-passkey key recovery in Google Password Manager, and Windows Hello key reuse.
SpecterOps' Pass-the-Passkey research showed Windows stored past YubiKey signatures in cleartext and chained this with Microsoft Entra ID passkey validation weaknesses to impersonate privileged users despite phishing-resistant MFA; the Windows Event Logging Service issue is tracked as CVE-2026-34348 (CVSS 6.5) and fixed in July 2026 updates. Unit 42's Golden Pass-ta-key attack recovered the 32-byte Security Domain Secret protecting Google Password Manager synced passkeys from Chrome on Windows via pre-existing malware. Dirk-jan Mollema showed in-session malware can use a hardware-bound Windows Hello for Business key without a fresh PIN or biometric check. Microsoft applied Entra-side mitigations for the relay assertion issue; no real-world exploitation has been reported.
