CVE-2026-107270
Gophish through 0.12.1 contains an insecure direct object reference vulnerability that allows authenticated users to take over other users' groups, templates, landing pages and sending profiles. Attackers can supply another user's sequential id in POST requests to /api/groups/, /api/templates/, /api/pages/ or /api/smtp/ to overwrite and reassign objects, locking out owners and exposing victims' recipient lists.
CVSS
- Version: 4.0
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:N/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: 7.1
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.20%
- Percentile among all scored CVEs: 9
- Score date: 10/17/2026
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).
