Parallels Desktop Flaw Lets Non-Admin Mac Users Gain Root, but Intel Macs Can't Install Fix

JFrog disclosed CVE-2026-90894, a 7.8-rated local privilege escalation in Parallels Desktop for Mac, patched only in version 27, which Intel Macs cannot install.

JFrog researcher Yuval Moravchick disclosed CVE-2026-90894 (dubbed ParaShells, CVSS 7.8), a local privilege escalation in Parallels Desktop for Mac that lets non-admin users run code as root. The root-level prl_disp_service listens on a world-writable socket, and argument injection into a tar command via QProcess::splitCommand and the --use-compress-program option yields code execution as root, demonstrated on Parallels Desktop 26.4.0 build 57513 on Apple silicon. The fix appears in version 27.0.0, but Parallels Desktop 27 requires Apple silicon, leaving Intel Macs on the 26.x line with no build JFrog describes as fixed. No exploitation in the wild has been reported and Parallels has not published a statement.

Parallels Desktop Vulnerability Lets Non-Admin Mac Users Execute Code as Root

JFrog researchers disclosed CVE-2026-90894, a critical Parallels Desktop local privilege escalation letting non-admin Mac users execute code as root; fixed in 27.0.0.

JFrog researchers found that Parallels Desktop's privileged prl_disp_service daemon on macOS accepts unsigned local clients through a world-writable socket and allows argument injection into a tar command during appliance installation. Injecting the --use-compress-program option makes tar execute an attacker-controlled program as root, and a one-line proof of concept yielded a root shell without needing a running virtual machine. The flaw, dubbed ParaShells, was confirmed in Parallels Desktop 26.4.0 build 57513 on Apple Silicon and is fixed in version 27.0.0. No exploitation in the wild has been reported; administrators should inventory and upgrade affected installations and restrict local account access.

Flock cameras are riddled with security vulnerabilities and hardcoded creds

Leaked Flock ALPR camera firmware reveals EOL Android 8.1, a 2017 Linux kernel, and hardcoded API keys granting access to production credentials.

DDoSecrets published filesystem images from an in-use Flock ALPR camera, obtained by the hacker collective stegan0gram and investigated by 404 Media and Wired. Micah Lee's analysis shows the camera runs Android 8.1 with a security patch level of 2018-06-05 and Linux kernel 3.18.71, missing roughly eight years of Android fixes. The firmware exposes a hardcoded API key for Flock's hpnotiq backend that can retrieve Auth0 client credentials for any camera by MAC address, with credentials stored in plaintext. Likely unpatched flaws include CVE-2021-1905 (Qualcomm Adreno use-after-free) and CVE-2018-9568 (WrongZone kernel socket type confusion); Flock says it received no reports via its disclosure policy.

Parallels Desktop flaw hands any local user root on a Mac (CVE-2026-90894)

CVE-2026-90894 in Parallels Desktop for Mac lets any local user gain root via argument injection; patched in v27.0.0, PoC withheld.

JFrog researchers disclosed CVE-2026-90894, an argument injection flaw in Parallels Desktop for Mac v26.4.0 on Apple silicon that lets any local user gain root on the host. The chain combines a world-writable Unix socket for prl_disp_service (which runs as root), weak peer-credential authentication, and argument injection via --use-compress-program in the appliance extraction tar path. Alludo fixed the flaw in Parallels Desktop v27.0.0 in early September 2026; JFrog published technical details but withheld its proof-of-concept script.

Parallels Desktop Flaw Lets Unprivileged Mac Users Gain Root Access

JFrog's 'ParaShells' research details CVE-2026-90894, a Parallels Desktop local privilege escalation letting unprivileged macOS users gain root via tar argument injection.

JFrog researcher Yuval Moravchick disclosed CVE-2026-90894 ('ParaShells'), a critical local privilege escalation flaw demonstrated against Parallels Desktop 26.4.0 build 57513 on Apple silicon. The world-writable /var/run/prl_disp_service.socket accepts connections from unsigned clients, and argument injection into a tar extraction command via the --use-compress-program option executes attacker-controlled code with root privileges. The attack needs no administrator permissions, running VM, or Parallels-signed client, and a one-line PoC yielded a root shell. Risk is highest on developer workstations, shared training systems, and enterprise Macs.

NightEagle Hackers Target Russian Companies Using GhostContainer Backdoor

Kaspersky links NightEagle (APT-Q-95) intrusions in Russia to stolen VPN credentials, the GhostContainer Exchange backdoor, BlueKeep exploitation, and covert tunneling for espionage.

Kaspersky's Global Emergency Response Team attributes new intrusions against Russian companies to NightEagle (APT-Q-95), active since at least 2023 and previously focused on Asian organizations. The group uses valid VPN credentials, deploys the .NET-based GhostContainer backdoor on Microsoft Exchange servers, and tunnels RDP via Microsoft Dev Tunnels and rdp2tcp. In one incident operators exploited BlueKeep (CVE-2019-0708) to create an administrator account, and they performed DCSync replication against Active Directory to harvest domain password hashes. GhostContainer reuses code from Neo-reGeorg, ExchangeCmdPy.py (CVE-2020-0688), and ysoserial, and tampers with AMSI and Windows event logging to evade detection.

Cisco Secure Firewall Threat Defense Software TLS 1.3 Denial of Service Vulnerability

A TLS 1.3 buffer management flaw in Cisco Secure Firewall Threat Defense lets remote attackers crash the LINA process and reload devices.

A vulnerability in the TLS 1.3 implementation of Cisco Secure Firewall Threat Defense (FTD) software allows an unauthenticated remote attacker to cause a denial of service via crafted TLS 1.3 packets sent to a TLS 1.3-enabled listening socket. Improper buffer management causes the LINA process to crash, forcing a device reload that can occur before or after connection authentication. Cisco has released software updates to address the flaw.

NightEagle targets Russian companies

Kaspersky links NightEagle (APT-Q-95) attacks on Russian firms to compromised VPN credentials, a GhostContainer Exchange backdoor, RDP tunneling, BlueKeep exploitation, and DCSync.

Kaspersky's Global Emergency Response Team investigated NightEagle (APT-Q-95) incidents over the past year, finding the group—active since at least 2023 and formerly focused on Asia—now targeting Russian businesses. Attackers used compromised VPN credentials and deployed the GhostContainer .NET backdoor on Microsoft Exchange servers, built from Neo-reGeorg, a CVE-2020-0688 exploit, and ysoserial's GhostWebShell, injected in memory via VIEWSTATE manipulation with AMSI bypass. For lateral movement they combined Microsoft dev tunnels with rdp2tcp over RDP, exploited BlueKeep (CVE-2019-0708) to create local admin accounts, and performed DCSync replication against Active Directory.
