CVE-2023-0677Public exploitNetwork attack vector

Script execution via unescaped invalid-recipient errors

Published Feb 4, 2023 · Updated Mar 26, 2025

Reflected XSS in phpIPAM before 1.5.1 allows attackers to execute script via crafted invalid recipient input returned in an error. The mail-notification and temporary-share handlers append invalid recipient values to HTML error messages without applying escape_input(). Exploitation requires a victim to process the crafted request, and script execution remains confined to that victim's browser context.
