AVideo-Encoder 發現未授權全回應伺服器端請求偽造漏洞（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.

The Common Vulnerability Scoring System is a standardized framework for assessing the severity of vulnerabilities in software and systems. We collect and displays CVSS scores from various sources for each CVE.

Update AVideo to fix SSRF flaws by validating URLs, enabling TLS verification, and properly configuring network access controls.

• Update AVideo to the latest secure version.
• Validate all external URLs against a strict allowlist.
• Enable and enforce TLS peer verification.
• Configure network access controls to restrict internal access.
