Insecure Library Loading is a cybersecurity vulnerability that occurs when software loads external libraries or modules from untrusted or unintended locations. Attackers can exploit this flaw by placing malicious libraries in directories that the application searches first, causing the software to load and execute the attacker’s code. This can lead to unauthorized access, privilege escalation, or system compromise. The issue often arises due to improper search order, lack of integrity checks, or insufficient path validation. To mitigate this risk, developers should use absolute paths, verify library integrity, and restrict search directories to trusted locations only.
