CVE-2023-0676Public exploitNetwork attack vector

Browser script execution via unvalidated calculator inputs

Published Feb 4, 2023 · Updated Feb 13, 2026

Reflected XSS in phpIPAM before 1.5.1 allows remote attackers to execute script in an authenticated user's browser via calculator input. The bandwidth calculator copies the wsize, delay, and fsize POST values into calculations without validating their numeric types, allowing fsize markup to reach the response. Exploitation requires an active phpIPAM session and victim interaction, and the injected script executes within that browser's phpIPAM origin.
