AnalysisAIv1 – Sep 15, 2026

Unauthenticated SQL injection in itsourcecode Leave Management System 1.0 lets a remote attacker manipulate the user_email argument of /login.php to alter the authentication query and read or subvert backend data. Exploit code has been made publicly available (reflected as exploit maturity E:P in the CVSS 4.0 vector and referenced from a GitHub issue), so any internet-reachable deployment should be treated as immediately attackable. The flaw is not listed in CISA KEV and no EPSS score was supplied, so active in-the-wild exploitation is not confirmed — but the low attack complexity and zero authentication requirement make opportunistic scanning likely.
