CVE-2025-40772
A vulnerability has been identified in SiPass integrated (All versions < V3.0). Affected server applications are vulnerable to stored Cross-Site Scripting (XSS), allowing an attacker to inject malicious code that can be executed by other users when they visit the affected page.
Successful exploitation allows an attacker to impersonate other users within the application and steal their session data. This could enable unauthorized access to accounts and potentially lead to privilege escalation.
CVSS
- Version: 4.0
- Vector: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X
- Base score: 7
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.32%
- Percentile among all scored CVEs: 23
- Score date: 10/6/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
