Actively Exploited Critical RCE and File-Read Flaws Dominate the Week

Unauthenticated arbitrary file read in GitLab CE/EE lets remote attackers retrieve files from the GitLab server via the repository commits API, which fails to confine paths and does not enforce authentication. All 18.7 releases through 19.3.2 are affected across the fix lines (before 19.1.8, 19.2.6, and 19.3.2). This is confirmed actively exploited (CISA KEV) and publicly available exploit code exists, making it an emergency-patch priority for any internet-reachable GitLab instance.

Server-side template injection in Adobe Commerce, Adobe Commerce B2B, and Magento Open Source allows remote unauthenticated attackers to execute arbitrary code by injecting special elements into the template engine (CWE-1336). Rated CVSS 10.0 with a changed scope, the flaw requires no user interaction and grants code execution in the context of the current user, per Adobe advisory APSB26-146. No public exploit has been identified at time of analysis, but the maximal score and unauthenticated network reach make this a top-priority patch for e-commerce operators.

Unauthorized file transfer and execution in the ConnectWise ScreenConnect client (all versions prior to 26.6.5) lets a party to an active remote session push and run files on the Host machine without authorization or the Host's confirmation under certain circumstances. This turns a legitimate support session into a code-execution channel against the remote endpoint; ScreenConnect servers are explicitly not affected. No public exploit identified at time of analysis, though the client's remote-support role makes it an attractive target.

Out-of-bounds write in Chrome's V8 JavaScript engine allows remote attackers to execute arbitrary code within the renderer sandbox by directing a user to a crafted HTML page. All Google Chrome versions prior to 153.0.8010.36 are affected across desktop platforms. Impact is bounded by Chrome's renderer sandbox - an attacker achieves control over the renderer process and can access browser-stored data such as session cookies and saved credentials, but reaching the host OS would require a separately chained sandbox escape exploit. No public exploit identified at time of analysis.

Symlink following (CWE-59) in the Windows Update Stack enables a locally authenticated attacker with standard user privileges to elevate to SYSTEM on multiple Windows 11 and Windows Server 2025 builds. The vulnerability is confirmed actively exploited per CISA KEV, with full confidentiality, integrity, and availability impact following privilege escalation. Vendor-released patches are available for all identified affected builds and should be treated as an urgent patching priority.

Heap-based buffer overflow in the Windows Advanced Local Procedure Call (ALPC) subsystem enables a low-privileged local attacker to elevate privileges to SYSTEM level across a broad range of Windows 10 and Windows Server releases. The flaw (CWE-122) resides in ALPC's message-handling internals, where crafted IPC payloads can corrupt heap memory in a way that redirects execution. No public exploit has been identified at time of analysis, and Microsoft has released patches covering all affected builds.

Remote code execution in Check Point Quantum Security Gateway and Quantum Security Management stems from a heap-based buffer overflow in the ASN.1 decoder that parses VPN certificates, reachable by unauthenticated remote attackers. Because the flaw sits in the certificate-handling path of the internet-facing VPN service, a single crafted certificate or handshake can overflow heap memory and execute attacker-controlled code on security appliances that sit at the network perimeter. No public exploit identified at time of analysis, and the CVE carries no EPSS or KEV signal, but the pre-auth network-reachable RCE profile makes it a top-tier patching priority.

Remote code execution in Check Point Quantum Security Gateway arises from improper certificate trust validation during VPN negotiation, letting a remote unauthenticated attacker run arbitrary code on the gateway itself. The CWE-295 root cause means the gateway accepts or mishandles an untrusted/forged certificate in the IKE/SSL-VPN handshake, and processing that malicious certificate leads to code execution rather than merely a trust bypass. No public exploit identified at time of analysis and the flaw is not listed in CISA KEV.
