CVE-2026-121434
CVE-2026-121434 updated by NVD
Summary
Froxlor 2.3.0 before 2.3.15 contains a missing authorization check in the Certificates.add and Certificates.update API commands, which do not verify whether a domain's certificate is Let's Encrypt-managed. Customers with API access can overwrite the managed certificate and private key with an attacker-chosen pair, which a REBUILD_VHOST task deploys to the webserver, breaking HTTPS and desynchronizing ACME automation.
