Actively Exploited Unpatched RCE and Privilege Flaws Lead the Week

SQL injection in Metabase's '/reset_password' database endpoint lets a remote, unauthenticated attacker inject arbitrary SQL and escalate to administrator on the connected Metabase instance. Rated CVSS 4.0 10.0 (CWE-89), it is network-exploitable with no authentication or user interaction, and full compromise of the application and its subsequent systems is achievable. No public exploit code is identified at time of analysis, but a vendor security advisory (GHSA-vwf4-m7j8-wcjf) and a CISA CSAF advisory (VA-26-222-01) both track the flaw, indicating coordinated, high-priority disclosure.

Denial of service via crafted HTTP requests to the Remote Access SSL VPN service affects Cisco Secure Firewall ASA and FTD Software across a broad range of versions, enabling unauthenticated remote attackers to force an unexpected device reload and take down the firewall entirely. The Changed scope (S:C) in the CVSS vector reflects that the impact extends beyond the VPN process itself to the entire device, disrupting all traffic passing through it. This vulnerability is confirmed actively exploited (CISA KEV), with SSVC marking it as automatable, making it a high-priority remediation target for any organization with internet-exposed ASA or FTD VPN endpoints.

Reachable assertion in Open5GS up to version 2.7.6 allows remote unauthenticated attackers to crash the Diameter CER handler, causing a denial of service. The vulnerability exists in diam_log_func within lib/diameter/common/init.c, where a call to ogs_assert_if_reached() could be triggered by a crafted Capabilities Exchange Request message over the Diameter protocol. A public exploit exists and a patched release (v2.7.7) is available; no active exploitation has been confirmed via CISA KEV.

Privilege escalation in the Windows Ancillary Function Driver for WinSock (afd.sys) allows a locally authenticated attacker to gain SYSTEM-level privileges through a use-after-free memory corruption flaw. Affected systems include Windows installations where the WinSock subsystem is active, which covers virtually all Windows deployments. No public exploit code or active exploitation has been identified at time of analysis, though the high-complexity exploitation bar somewhat limits immediate opportunistic risk.

Remote code execution in the Fabrik application-builder extension for Joomla (all versions before 4.6.8) lets an unauthenticated attacker run arbitrary code on the server via the frontend listfilter model. The flaw is a CWE-94 code injection reachable over the network with no authentication or user interaction, and the vendor rates it maximum severity (CVSS 4.0 base 10.0). No public exploit code has been identified at the time of analysis, and it is not listed in CISA KEV, but the combination of unauthenticated access and full code execution makes it a top-priority patch.

Remote code execution and denial-of-service in Phoenix Contact PLCnext-family industrial controllers (AXC F 1152/1252/2152/3152, RFC 4072R/S, BPC 9102S/9202S, VPLCnext Control, EPC 15xx and others) arise from a buffer overflow in the PROFINET service that is reachable in the default configuration. An unauthenticated remote attacker on the network can crash/reboot the device or execute arbitrary code, per the vendor CVSS 4.0 rating of 9.3 (critical). This is a CWE-120 classic buffer overflow reported by CERT@VDE; no public exploit identified at time of analysis and it is not on CISA KEV.

PHP Object Injection escalating to unauthenticated remote code execution affects the WooCommerce Subscriptions WordPress plugin from version 4.7.0 up to (but not including) 9.1.0, but only on stores running WooCommerce's High-Performance Order Storage (HPOS). The plugin unserializes attacker-controlled input without validation, and a gadget chain in bundled dependencies turns that into arbitrary code execution. Publicly available exploit code exists and a vendor patch (9.1.0) is available, but this is not listed in CISA KEV; the EPSS score of 28% is elevated, indicating meaningful exploitation probability.

Denial of service in Open5GS 2.7.6 and earlier allows network-adjacent attackers with low-privilege Diameter Gx peer access to crash the Session Management Function (SMF) by sending a malformed Credit-Control-Answer (CCA) message to the smf_gx_cca_cb handler. A publicly available proof-of-concept crash sample (SMF.crashes.zip) confirms exploitability; the absence of a CISA KEV listing indicates no confirmed widespread threat-actor exploitation has been reported. In 5G/4G core network deployments, an SMF crash disrupts session management for all connected user equipment, making this a higher operational risk than the CVSS medium score alone suggests.
