CVE-2025-39566
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Bob Hostel hostel allows Blind SQL Injection.This issue affects Hostel: from n/a through <= 1.1.5.6.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA blind SQL injection vulnerability exists in the Bob Hostel application where user-supplied input is not properly sanitized before being used in SQL queries. An attacker can inject malicious SQL statements through unsanitized input parameters to extract data from the database by observing behavioral differences between true and false conditions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Bob Hostel application in useSearch for files, directories, or web applications containing 'bob hostel' or 'Bob Hostel' in the environment. Check web server logs, installed applications, or source code repositories for this application name.Affected if The Bob Hostel application is present in the environment
-
Locate database interaction codeSearch source code for SQL query patterns: look for executeQuery, query, rawQuery, or direct SQL statement construction that interacts with a database.Affected if SQL queries exist in the application code
-
Identify user input pointsReview code for where user input is received: HTTP request parameters, form inputs, URL parameters, headers, or API payloads that flow into database queries.Affected if User-supplied data is used in SQL queries without clear sanitization
-
Check for parameterized queriesExamine SQL query code for use of prepared statements, parameterized queries, or bound parameters (e.g., ? placeholders with bound values). Search for patterns like 'PreparedStatement', 'parameterized', 'bind_param', or similar.Affected if SQL queries use string concatenation or interpolation instead of parameterized queries
-
Inspect input validationLook for input validation routines that sanitize or escape SQL special characters (quotes, semicolons, UNION, SELECT, etc.) before including user input in queries.Affected if No input validation or sanitization is performed on user input before database queries
The environment is affected if the Bob Hostel application is present and user input flows directly into SQL queries without parameterized queries or input validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace dynamic SQL queries with parameterized queries/prepared statements and implement proper input validation on all user-supplied data before database interaction.
