CVE-2025-7174
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 · uneditedA vulnerability was found in code-projects Library System 1.0 and classified as critical. This issue affects some unknown processing of the file /teacher-issue-book.php. The manipulation of the argument idn leads to sql injection. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.
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 · moderate confidenceSQL injection vulnerability in the 'idn' parameter of /teacher-issue-book.php in code-projects Library System 1.0 allows remote unauthenticated attackers to execute arbitrary SQL commands via the vulnerable parameter in the teacher-issue-book processing.

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.
-
Confirm Code Projects Library System versionInspect the application footer, about page, or any version documentation to verify the installed version is exactly 1.0Affected if The application is Code Projects Library System version 1.0
-
Locate teacher-issue-book.phpCheck if the file /teacher-issue-book.php exists in the web root or application directoryAffected if The file teacher-issue-book.php exists and is accessible via web
-
Verify 'idn' parameter is acceptedSend a GET or POST request to teacher-issue-book.php and inspect whether the 'idn' parameter is processed without errorAffected if The 'idn' parameter is accepted and processed by the application
-
Identify SQL query handling for 'idn'If source code is accessible, examine teacher-issue-book.php to locate SQL queries that incorporate the 'idn' parameter directlyAffected if The 'idn' parameter is used in a SQL query without parameterized queries or proper escaping
A user is affected if they run Code Projects Library System 1.0 with teacher-issue-book.php accessible and the 'idn' parameter used in unsanitized SQL queries.

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 for the 'idn' parameter, implement proper input validation, and apply any vendor security patches if available.
