CVE-2026-62988: Froxlor: Credential and 2FA secret disclosure via Froxlor API endpoints
Froxlor is open source server administration software.
CVSS 9.0 Critical EPSS 0.6% · p49
Should you act?
Critical, preconditions apply
Severe if exploited, but exploitation needs conditions that may not apply to you. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.6%, percentile 49: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 49% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs an account (high (admin)). Exposure depends on who can log in.
- Only applies if your dependency tree includes
froxlor/froxlor(Composer (PHP)) < 2.3.8, fixed in 2.3.8. Check your lockfile, including transitive dependencies.
What it is
Froxlor is open source server administration software. From 2.3.7 until 2.3.8, the Customers.get, Customers.listing, Admins.get, Admins.listing, Ftps.get, and Ftps.listing API commands in lib/Froxlor/Api/Commands/Customers.php, lib/Froxlor/Api/Commands/Admins.php, and lib/Froxlor/Api/Commands/Ftps.php retrieve full database rows and return them without removing password and data2fa fields. An authenticated API caller with permission to use these endpoints can obtain customer, administrator, and FTP password hashes as well as Base32-encoded TOTP seeds for administrator and customer accounts. Password hashes can be cracked offline, and TOTP seeds can generate valid second-factor codes until two-factor authentication is reset. Exposure of both values for an account can enable takeover of the hosting panel or hosted resources and can defeat both authentication factors. This issue is fixed in version 2.3.8.
From the GitHub advisory
Summary
Several Froxlor API command classes return sensitive authentication material in JSON API responses. The affected endpoints retrieve full database rows using SELECT , SELECT alias., or equivalent full-row queries, then return the results directly through $this->response(...) without removing credential-related fields.
The exposed fields include password hashes for customers, administrators, and FTP users, as well as TOTP 2FA seed material for administrator and customer accounts.
This exposes credential-equivalent data to API clients that should not receive it. Password hashes can be cracked offline and reused for account takeover, while exposed TOTP seeds allow generation of valid 2FA codes for affected accounts. When both a password hash and TOTP seed are exposed for the same account, the vulnerability can defeat both authentication factors if the password hash is cracked or the password is otherwise obtained.
