RCE Vulnerability in AI Code Editors Cursor, VS Code and Google Antigravity Threatens 50 Million Developers
Researchers at AISLE discovered a critical remote code execution vulnerability affecting the AI-powered code editors Cursor, Microsoft Visual Studio Code and Google Antigravity. The flaw allowed attackers to achieve RCE simply by tricking a developer into opening a specially crafted link embedded in a Git commit message. Successful exploitation granted full access to API keys, local files, and the ability to install persistent malware without any visible indicators. The issue stemmed from shared architectural components inherited from the Visual Studio Code codebase, which Cursor and Google Antigravity both adopted. All three vendors have released patches, yet the incident highlights systemic supply-chain risks in the rapidly growing AI-IDE ecosystem. Approximately 50 million developers were potentially exposed before fixes were deployed.
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.

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.
