CVE-2026-12877Public exploitNetwork attack vector

Unauthenticated SQL injection via raw search query

Published Jul 24, 2026 · Updated Jul 24, 2026

SQL injection in Software Issue Manager before 5.1.0 allows remote attackers to execute arbitrary SQL through its front-end search form. The search-query rewrite concatenates the raw s parameter into title and content LIKE clauses in a UNION query without sanitization or escaping. Exploitation requires front-end author limiting and a published guest-submitted issue; injected SQL can read or alter data available to the WordPress database account.
