CVE-2026-61572

AVideo is a video-sharing Platform. Before the initial remediation attempt in 8.1.0, `url_get_contents` in `objects/functions.php` accepts caller-controlled destinations after only `FILTER_VALIDATE_URL` syntax validation, without rejecting private, loopback, or link-local addresses, and disables TLS peer verification. `Login::isLogged` reauthenticates using the attacker-settable `encoder_aVideoURL` cookie together with arbitrary nonempty `encoder_user` and `encoder_pass` cookies, and `Login::run` stores the raw fetched body in `result`. The unauthenticated `objects/login.json.php` endpoint returns that session object, enabling full-response exfiltration through a supplied `siteURL`; its `Streamer::isURLAllowed` gate allows all sites when the operator allowlist is empty, the default. An unauthenticated remote attacker can read internal HTTP and HTTPS responses, including cloud instance-metadata credentials, and reach internal TCP services. A further pre-authentication FTP variant in `view/youtubeDl.json.php` routes an ftp `videoURL` into `FTPDownloader`; `parseFtpUrl` in `objects/FTPDownloader.php` accepts its host and port for `ftp_connect`. This also enables requests to internal FTP services. Untrusted self-signed HTTPS certificates are accepted, and no account or operator interaction is required. Version 8.1.0 contains an initial remediation attempt that removes raw-response reflection and adds destination checks, but private-network exemptions and login TLS-verification defaults leave complete remediation of the described internal-network and TLS variants unresolved.
