Weekly Vulnerability Briefing: Unpatched Critical RCE Dominates Findings

Remote code execution in WGDashboard (a self-hosted WireGuard management web UI) versions up to 4.3.2 lets attackers inject OS commands that execute as root through multiple unsanitized input paths (CWE-78). Publicly available exploit code exists (Stuub PoC targeting v4.3.2), and CISA's SSVC framework rates the technical impact as total and the flaw as automatable, though it is not listed in CISA KEV. Note a data conflict: the CVSS vector marks this as unauthenticated (PR:N) while the description states exploitation requires an authenticated attacker.

Arbitrary file deletion in the Custom Fields WordPress plugin before 1.5.1 allows unauthenticated attackers to delete any file on the server - including wp-config.php - leading to full site takeover. Because the plugin fails to validate a user-supplied path before deletion, a remote attacker needs no authentication or user interaction (CVSS 10.0). Publicly available exploit code exists via WPScan, though EPSS is low (0.17%) and the flaw is not listed in CISA KEV.

SQL injection in the Sequelize Node.js ORM (versions prior to 6.37.4) allows remote attackers to inject arbitrary SQL through application values that reach the string-escaping routine, but only when the ORM is configured with the Oracle dialect. The escape() function in sql-string.js returns any string beginning with TO_TIMESTAMP or TO_DATE verbatim without doubling single quotes, letting a crafted value break out of the intended literal. Publicly available exploit code exists in the GitHub Security Advisory (GHSA-v8fg-2rw7-q452); there is no CISA KEV listing and no EPSS score was provided.

Unauthenticated remote code execution in the Webinfos WordPress plugin (versions through 1.2) lets any anonymous attacker upload arbitrary files - including PHP webshells - because the plugin's upload handler enforces no file-type validation, authentication, capability, or nonce checks. On servers that execute PHP from the uploads directory, this yields full server compromise. Publicly available exploit code exists (reported by WPScan), and while EPSS is currently low at 0.28%, the CVSS 9.8 rating and automatable, unauthenticated nature make this a high-priority patch target.

Remote code execution in WGDashboard 4.3.2 and earlier lets authenticated attackers inject Server-Side Template Injection payloads that execute arbitrary commands as root, giving full host compromise. Publicly available exploit code exists (Stuub's SSTI-to-Root-RCE PoC), though the flaw is not listed in CISA KEV and carries a low EPSS score of 0.28% (20th percentile), indicating no evidence of widespread automated exploitation yet. The combination of a working PoC and root-level impact makes this a high-priority patch target for any internet-exposed WGDashboard instance.

Unrestricted file upload in ICS-Park Smart Park Management System v2.0 lets a remote attacker upload and execute arbitrary code through the product's file upload module, yielding full server compromise (CVSS 9.8). Public exploit code exists and the flaw is automatable with total technical impact per CISA SSVC, though the EPSS probability remains low at 0.26% (17th percentile), indicating limited observed exploitation activity so far. No CISA KEV listing means no confirmed active exploitation at time of analysis.

PHP Object Injection in the Ajax Search Lite WordPress plugin before 4.14.5 lets unauthenticated remote attackers pass untrusted serialized data into a PHP unserialize() sink, and where a suitable POP gadget chain exists in a co-installed plugin or theme, this escalates to remote code execution. Reported by WPScan with publicly available exploit code, it carries a CVSS 9.8 rating but a low EPSS of 0.22% (13th percentile), and is not listed in CISA KEV. A vendor patch is available in version 4.14.5.

Remote code execution in the Personal QR Message WordPress plugin (versions through 1.0) allows unauthenticated attackers to upload arbitrary PHP files via a handler that fails to restrict uploaded file types, and those files are directly reachable and executable on the server. Publicly available exploit code exists (published by WPScan), and the CVSS 3.1 base score is 9.8, though the EPSS probability is low at 0.22% (13th percentile). This is a classic unauthenticated file-upload-to-RCE flaw that grants full server compromise with no authentication or user interaction.
