phpMyFAQ 3.2.0 before 4.1.9 and 4.2.0-alpha before 4.2.0-beta contains an insecure direct object reference vulnerability in GET /admin/api/user/data/{userId}, which returns any user's full faquserdata row, including the live TOTP secret, without a SuperAdmin or protected-target check. Delegated administrators with user-management rights can read a SuperAdmin's TOTP secret and generate valid codes to bypass two-factor authentication.

CVSS

Base score: 7
Version: 4.0
Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:L/VA:L/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

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.34 %
Percentile among all scored CVEs: 26
Score date: 10/20/2026

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).
