The advisory, released on August 6, 2026, covers a total of twelve issues including cross-site scripting, privilege escalation, information disclosure, and server-side request forgery.

The most prominently detailed flaw is CVE-2026-64638, a reflected cross-site scripting vulnerability located on the login screen. The issue can be triggered in an unauthenticated state when a victim is lured to a malicious external site and performs specific actions. Under certain conditions the attack can result in execution of arbitrary PHP code on the target WordPress installation.

According to the Common Vulnerability Scoring System version 4.0, CVE-2026-64638 received a base score of 8.9 and is classified as High severity. Although only one CVE identifier appears in the advisory, the update resolves the full set of twelve problems.

Site owners are strongly encouraged to upgrade to WordPress 7.0.3 without delay to mitigate the reported risks.

NEOMSA APIM 4.6.0 Eliminates All Critical and High Vulnerabilities Registered in FSTEC BDU

Neoflex has released NEOMSA APIM 4.6.0 with a primary focus on strengthening the security of the platform's supply chain. The team generated an SBOM in CycloneDX format, scanned components and dependencies using Grype, and cross-referenced findings against the FSTEC BDU database. This process reduced total registered vulnerabilities from 57 to 7, completely removing all 10 Critical and 24 High issues. The platform now meets the formal Security Gate criterion requiring zero Critical or High vulnerabilities from the FSTEC database in the final build. Remaining Medium findings are documented and tracked for future updates. The release provides customers with a verified, transparent component inventory that simplifies compliance and integration reviews.

Head Mare Hackers Exploit TrueConf Servers to Distribute PhantomCore and PhantomGraph Backdoors

Russian organizations have been targeted in a new campaign by the Head Mare group, which compromises unpatched TrueConf servers to deliver backdoors. Attackers chain vulnerabilities KLCERT-26-057 and KLCERT-26-058 to execute arbitrary code with maximum privileges on affected servers. They then replace a server file with a web shell to explore the victim's infrastructure, access the TrueConf database, and substitute the client installer. Victims are tricked via social engineering into downloading the malicious client during video conferences without any suspicious emails. The campaign affects TrueConf Server versions 5.3.X through 5.3.9, 5.4.X through 5.4.9, 5.5.X through 5.5.5, and earlier releases. Kaspersky researchers recommend immediate updates to patched versions 5.3.9, 5.4.9, and 5.5.5 released on 18 June 2026. The threat extends beyond direct TrueConf users, as any employee invited to a compromised server can inadvertently install the backdoor.

Zapscape Flaw in KVM Breaks Nested Virtualization Isolation Allowing L1 Guest Root Code Execution on Linux Host

The Zapscape vulnerability (CVE-2026-64561) affects KVM/x86 in the Linux kernel and enables an attacker with kernel privileges inside an L1 virtual machine to escape to the host and execute code as root. The flaw occurs in the shadow MMU when handling page faults for nested guests, specifically due to an incorrect order of stale root condition checks that leads to a use-after-free condition. This weakens the isolation between the host and L1 guests precisely when nested virtualization is enabled for potentially untrusted tenants. A public proof-of-concept demonstrates the escape by creating a file named /Zapscape owned by root on the host. The issue impacts Linux kernels starting from version 5.9, with fixes already merged into stable branches including 6.6.148, 6.12.101, 6.18.42, 7.1.6 and 7.2 rc5. On Intel systems the attack requires EPT page walk lengths 4 and 5 to be exposed to the L1 guest, while no equivalent condition is documented for AMD. Organizations are advised to apply patches promptly or disable nested virtualization for untrusted workloads.
