CVE-2026-70555

Not enough EPSS history yet.

rConfig Core 8.2.3 before 8.2.13 contains an information disclosure vulnerability that allows authenticated users to retrieve cleartext SSH, Telnet, and enable passwords for managed devices through the device-credentials API due to automatic decryption on read and missing authorization checks. Attackers can request GET /api/device-credentials, GET /api/device-credentials/{id}, or the external GET /api/v1/device-credentials endpoint, which authenticates any valid token as the seeded administrator account, to statelessly exfiltrate all stored plaintext device credentials. rConfig Pro is not affected.
