Since 30 August 2026, honeypots have recorded active attacks against the CVE-2026-9586 flaw. On 1 September, researchers at Horizon3.ai published the technical details, sharply lowering the barrier to entry for further attackers.<\/strong><\/p>\n\n<h3 class=\"wp-block-heading\">What makes the flaw so dangerous<\/h3>\n\n<p class=\"wp-block-paragraph\">CVE-2026-9586 is an unauthenticated SQL injection that can be escalated to remote code execution. The unprotected <code>\/pa<\/code> endpoint processes XML messages from IP phones and writes the <code>PhoneIP<\/code> field directly into a PostgreSQL query with no sanitisation whatsoever. A single crafted HTTP request is enough to run commands with database superuser privileges. The flaw carries a critical CVSS 4.0 score of 9.3.<\/p><div id=\"netgu-1555656162\" class=\"netgu-content netgu-entity-placement\"><aside class=\"deals-top deals-top--compact\">\n\n\t\t\t<h3
