No affected components available
Summary
A SQL Injection vulnerability in Fleet’s software versions API allowed authenticated users to inject arbitrary SQL expressions via the order_key query parameter. Due to unsafe use of goqu.I() when constructing the ORDER BY clause, specially crafted input could escape identifier quoting and be interpreted as executable SQL.
Impact
An authenticated attacker with access to the affected endpoint could inject SQL expressions into the underlying MySQL query. Although the injection occurs in an ORDER BY context, it is sufficient to enable blind SQL injection techniques that can disclose database information through conditional expressions that affect result ordering. Crafted expressions may also cause excessive computation or query failures, potentially leading to degraded performance or denial of service.
No direct evidence of reliable data modification or stacked query execution was demonstrated.
Workarounds
If an immediate upgrade is not possible, users should restrict access to the affected endpoint to trusted roles only and ensure that any user-supplied sort or column parameters are strictly allow-listed at the application or proxy layer.
