AI Threat Summary
CVE-2026-61569 is a high-severity vulnerability with a CVSS score of 7.5 affecting the target software. This vulnerability allows SQL injection leading to unauthorized data access. Authentication can be bypassed allowing unauthenticated access. Threat hunters should monitor for exploit attempts and apply vendor patches immediately.
Description
AVideo is a video-sharing Platform. Prior to 8.1.0, the unauthenticated streamer login at `objects/login.json.php` passes the `user` parameter to `Streamer::get` in `objects/Streamer.php`, where it is interpolated into a single-quoted MariaDB SELECT without parameterization or escaping. Although `objects/security.php` strips literal single quotes, `html_entity_decode` in `objects/Login.php` restores entity-encoded quotes before the query. The supplied `siteURL` must pass the streamer allowlist, which allows all sites when empty by default, and an attacker-hosted login response must set `canUpload` or `isAdmin` to reach `Streamer::createIfNotExists`. That function calls `Streamer::get` before its additional allowlist check. UNION results are exposed through `streamers_id`, while failures return the rendered query and MariaDB error. An attacker can read arbitrary encoder database data, including stored upstream streamer credentials, allowlist configuration, and queue records, without encoder credentials. Stacked statements are not permitted by the mysqli driver and the tested database account lacks global FILE privilege, so the demonstrated vector is bounded to reads rather than server-side file writes. Stolen streamer credentials can provide continued upstream access until rotated. This issue is fixed in version 8.1.0.
Attack Chain
Attacker fingerprints web application and identifies injectable parameters using automated scanners
Attacker injects SQL payload via vulnerable parameter to bypass authentication or extract data
Attacker dumps database tables including user credentials, session tokens, and sensitive data
Extracted password hashes cracked offline using hashcat/john or plain-text credentials used directly
Valid credentials reused across other systems and services in the environment
MITRE ATT&CK Techniques
SQL injection exploited against web application database layer
Database contents exfiltrated including credentials and PII
Credentials stolen from database used for further access
