Acronis Plugin Vulnerability in cPanel and Plesk Exploited in the Wild

Acronis patched CVE-2026-87886 (CVSS 7.8), a local privilege escalation flaw in its cPanel and Plesk backup plugins, exploited in targeted attacks.

Acronis released fixes for CVE-2026-87886 (CVSS 7.8, CWE-276), an insecure file permissions flaw in Linux-based backup components for cPanel & WHM and Plesk that enables local privilege escalation. The vendor observed limited, targeted exploitation in the wild before patches shipped. Fixes are available in Backup plugin for cPanel & WHM 1.9.3 HF3 and Backup extension for Plesk 1.8.11. A local attacker with low privileges could gain elevated access to backup data, control panels, and other customer accounts on shared hosting infrastructure.

BGP Hijack Delivers Malicious Virtualizor Update That Establishes Persistent Root Access

Attackers used a BGP hijack to divert Softaculous traffic and push a malicious Virtualizor update granting root persistence on some hypervisors.

Virtualizor reported that a BGP hijack between August 28 20:57 UTC and August 30 06:10 UTC diverted Softaculous update traffic to an attacker-operated server holding a valid Let's Encrypt certificate. Installations checking for updates during the window could receive a malicious package that added an attacker SSH key to root, created a proxyuser account, and installed a Java payload persisted via a systemd service. Hosting provider AlbaHost confirmed 5 of its 34 Virtualizor hypervisors were root-compromised. Virtualizor shipped Patch 9 with a Security Analyzer on September 1, but cryptographic package signing remains future work.

PaperCut NG/MF vulnerabilities exploited in zero-day attacks

PaperCut warns of active zero-day exploitation chaining CVE-2026-81578 and CVE-2026-82078 for pre-auth remote code execution in NG/MF print management.

PaperCut Software confirmed attackers are chaining two vulnerabilities in PaperCut NG and MF: CVE-2026-81578, an improper access control flaw in the web management interface allowing unauthenticated configuration changes, and CVE-2026-82078, unsafe dynamic class loading in database connection utilities enabling arbitrary Java bytecode execution. Huntress reproduced a pre-authentication remote configuration takeover and full RCE chain against PaperCut NG 25.0.11.75758 and observed limited exploitation at two customers, including post-exploitation whoami and ver commands. The vendor released Emergency Patch Release 2 with additional hardening and urged restricting Application Server web access to trusted IPs. In 2023, Clop and LockBit affiliates abused CVE-2023-27350 and CVE-2023-27351 in the same software.

Unpatched Zimbra servers are falling to CVE-2026-73570 attacks

Attackers are exploiting unpatched Zimbra servers via CVE-2026-73570; 274 instances compromised, and CISA added the flaw to its KEV catalog.

The Shadowserver Foundation counted at least 274 compromised internet-facing Zimbra Collaboration Suite instances exploited through CVE-2026-73570, up from 155 on August 20. The unauthenticated code injection flaw affects servers with the optional zimbra-snmp package and SNMP notifications enabled, allowing arbitrary OS command execution via crafted SMTP requests. Synacor patched the issue in ZCS v10.1.20 on July 20, 2026, and at least 8,200 instances remain unpatched. CISA added the flaw to its Known Exploited Vulnerabilities catalog and gave US federal civilian agencies three days to remediate and check for compromise.

Attackers exploit patched macOS Screen Sharing flaw to deploy cryptominer

Attackers actively exploit patched macOS Screen Sharing bug CVE-2026-65400 on systems with port 5900 exposed, gaining root to install a Monero cryptominer.

The Netherlands' National Cyber Security Centre (NCSC) reports active exploitation of CVE-2026-65400, an authentication flaw in macOS Screen Sharing that lets attackers authenticate without valid login credentials. Apple patched the issue in macOS Sequoia 15.7.9, Sonoma 14.8.9 and Tahoe 26.6.1, and the NCSC escalated its advisory on August 12 after proof-of-concept code went public and reports arrived of attacks on internet-exposed systems. In every reported case attackers obtained root access and installed a Monero crypto miner; users who cannot patch immediately are advised to disable Screen Sharing.

CISA gives federal agencies two weeks to patch Microsoft bug exploited in DPRK campaign

CISA orders federal agencies to patch exploited Windows Winsock zero-day CVE-2026-68820 by August 25, used by Lazarus in Operation Dream Job.

CISA ordered federal agencies to patch Windows Winsock vulnerability CVE-2026-68820, rated 7/10, by August 25 after confirming exploitation; no workaround exists and a restart is required. Check Point found Lazarus Group hackers impersonated Lockheed Martin and Enveil recruiters on LinkedIn, sent malicious PDFs enabling long-term remote access, then used the zero-day to escalate from limited access to full system control. Targets spanned defense sectors including surveillance, drones and robotics in France, Germany, Brazil and India, as part of Operation Dream Job tracked since 2020.
