SCA: security update for pgadmin4 (GHSA-hv9p-2pqf-r5w3)

medium Tenable Cloud Security Plugin ID 442101

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Improper restriction of excessive authentication attempts (CWE-307) in pgAdmin 4. pgAdmin enforces
 MAX_LOGIN_ATTEMPTS only inside its custom /authenticate/login view. Flask-Security's default /login view,
 which is registered automatically by security.init_app() and is reachable on every server, never consulted
 the User.locked field: pgAdmin's User model relied on Flask-Security's UserMixin.is_locked() (which always
 returns 'not locked') and Flask-Login's is_active (which only checks the active column, not locked). An
 attacker who triggered an account lockout via /authenticate/login could therefore obtain a session by re-
 submitting valid credentials directly to /login, defeating the brute-force-protection control for accounts
 using the INTERNAL authentication source. The same bypass also means that login attempts via /login are
 never rate-limited, so an attacker can perform an unbounded online password-guessing attack against
 INTERNAL accounts regardless of MAX_LOGIN_ATTEMPTS. Fix overrides User.is_active and User.is_locked() so
 the locked column is enforced on every authentication path. LDAP, OAuth2, Kerberos, and Webserver users
 are not reachable by this bypass because they have no local password and are rejected by Flask-Security's
 LoginForm.validate before the locked check; the lockout itself is also internal-only (the
 /authenticate/login view filters by auth_source=INTERNAL). This issue affects pgAdmin 4: before 9.15.
 (CVE-2026-7820)

Solution

Update the pgadmin4 library and its related packages to version 9.15 or later.
