WWBN AVideo is an open source video platform. In versions up to and including 26.0, in `objects/like.php`, the `getLike()` method constructs a SQL query using a prepared statement placeholder (`?`) for `users_id` but directly concatenates `$this->videos_id` into the query string without parameterization. An attacker who can control the `videos_id` value (via a crafted request) can inject arbitrary SQL, bypassing the partial prepared-statement protection. Commit 0215d3c4f1ee748b8880254967b51784b8ac4080 contains a patch.

GHSA-fj74-qxj7-r3vc — AVideo has SQL Injection via Partial Prepared Statement — videos_id Concatenated Directly into Query

Affected: Packagist: wwbn/avideo

### Summary

In `objects/like.php`, the `getLike()` method constructs a SQL query using a prepared statement placeholder (`?`) for `users_id` but directly concatenates `$this->videos_id` into the query string without parameterization. An attacker who can control the `videos_id` value (via a crafted request) can inject arbitrary SQL, bypassing the partial prepared-statement protection.

### Details

**File:** `objects/like.php`

**Vulnerable code:** ```php $sql = "SELECT * FROM likes WHERE users_id = ? AND videos_id = ".$this->videos_id." LIMIT 1;"; $res = sqlDAL::readSql($sql, "i", [$this->users_id]); ```

The query mixes a parameterized placeholder for `users_id` with raw string concatenation for `videos_id`. The `$this->videos_id` value originates from user-supplied request input (typically a POST/GET parameter identifying the video being liked/disliked) and is not cast to integer or validated before being embedded in the SQL string.

All other queries in the same file correctly use `?` placeholders for both columns: ```php // Correct pattern used elsewhere: $sql = "SELECT count(*) as total FROM likes WHERE videos_id = ? AND like = 1"; ```

The inconsistency means any attacker who can submit a like/dislike action with a crafted `videos_id` can inject SQL. Since like/dislike actions are typically available to any authenticated user, the attack surface is broad.

### PoC

An attacker sends a like request with an injected `videos_id`: ``` POST /objects/likeAjax.json.php video…
