Improper Authentication in the social account linking path of the Prowler API in Prowler from 5.4.0 before 5.35.0 allows a remote unauthenticated attacker to obtain persistent access to the account of a user who has not yet registered, because ProwlerSocialAccountAdapter.pre_social_login() in api/src/backend/api/adapters.py links a Google or GitHub login to any existing local account that has the same email address as the one returned by the provider, without requiring that the address has been verified by the provider or on the existing account, and without any other check that both accounts belong to the same person. Self registration is open and the new account is usable at once, because UserViewSet.get_permissions() in api/src/backend/api/v1/views.py grants AllowAny to the create action, ACCOUNT_EMAIL_VERIFICATION is set to none in api/src/backend/config/settings/social_login.py, and the Django ModelBackend checks only the password and is_active, not the django-allauth EmailAddress record. An attacker who registers an email address before its owner keeps the password set at registration after the link is made, because sociallogin.connect() does not reset the password and does not disable the existing account, and the owner who later signs in with Google or GitHub is logged into the attacker's account. django-allauth makes the same email based link on its own, because SOCIALACCOUNT_EMAIL_AUTHENTICATION and SOCIALACCOUNT_EMAIL_AUTHENTICATION_AUTO_CONNECT are both set to True in the same settings module. This gives the attacker the cloud provider credentials, scan findings and tenant memberships held in the account.
CVE-2026-100169
“—” beside the score: it is equal to the CVSS score beside it.
This high-severity CVE scores 7.6 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.9% (58th percentile of EPSS-scored CVEs). No GitHub Security Advisory CVSS is on record for this CVE.

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".
