Deeper analysis

CVE-2025-70846 is a Cross-Site Scripting (XSS) vulnerability, classified under CWE-79, affecting lty628 aidigu version 1.9.1. The flaw occurs on the /tools/Password/add page within the password input field, where user-supplied input is not properly sanitized, enabling script injection.

The vulnerability carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating network accessibility, low attack complexity, no required privileges, and user interaction needed for exploitation, with a changed scope leading to low impacts on confidentiality, integrity, and availability. Unauthenticated attackers can exploit it by tricking users into submitting or interacting with malicious payloads on the affected page, potentially executing scripts in the victim's browser context.
