## Technical details

SOPlanning version 1.55 and below contains multiple SQL injection vulnerabilities (CWE-89) across various endpoints and parameters. The root cause is improper neutralization of special elements used in SQL commands. An authenticated attacker with low-level privileges can exploit these flaws by sending crafted network requests to vulnerable endpoints. Successful exploitation allows for the execution of arbitrary SQL commands, which can lead to unauthorized data exfiltration, modification, or full database compromise. The vulnerability was coordinated and disclosed by CERT Polska.
