Summary
CVE-2026-112142 is a high-severity SQL injection vulnerability in the Events-Management-System's Registration-Delete Handler. A remotely accessible request can manipulate the ID argument, potentially allowing database queries to be altered when the application processes registration deletions.
CVE-2026-112142 is a high-severity SQL injection vulnerability in the Events-Management-System's Registration-Delete Handler. A remotely accessible request can manipulate the ID argument, potentially allowing database queries to be altered when the application processes registration deletions.
Affected context
The vulnerability affects deployments of satya-vinay Events-Management-System that expose the dodelete.php registration-deletion functionality and incorporate the ID request argument into database operations without sufficient parameterization or validation. The risk depends on the handler being reachable over the network and on the database account having meaningful privileges.

Exploit preconditions
- Attack surface: Remotely accessible registration-deletion endpoint
- Required access: Ability to send requests to the affected handler; authentication requirements depend on the deployment
- Trigger point: Processing of the
IDargument bydodelete.php - Why exploitation is possible: The argument may influence a database statement without being safely separated from SQL syntax

Why this happens
The underlying issue is an injection flaw in which externally controlled input is incorporated into a database query as executable SQL rather than being treated strictly as data. This maps primarily to CWE-89: Improper Neutralization of Special Elements used in an SQL Command (SQL Injection) and is also related to CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component.

Potential impact
- An attacker may read unauthorized database records
- An attacker could alter or delete application data
- Database integrity and registration records may be compromised
- The application may disclose sensitive information
- Further impact may occur if the database account has excessive privileges

General mitigation guidance
Mitigation generally focuses on ensuring that request data cannot become part of executable SQL.
Common defensive patterns include:
- Using parameterized queries or prepared statements for every database operation
- Applying allowlisted validation for identifier values such as registration IDs
- Avoiding string concatenation when constructing SQL statements
- Restricting the database account to the minimum required permissions
- Separating application database credentials by environment and function
- Returning generic database errors without exposing query details
- Adding regression tests for all request parameters used in database operations

How teams detect issues like this
Organizations can look for this class of issue through:
- Static analysis rules that flag SQL construction using request parameters
- Code review checks for concatenation or interpolation in database queries
- Testing of identifier parameters with unexpected types and boundary values
- Web application firewall or database monitoring rules for suspicious query patterns
- Runtime logging of rejected validation events and database errors without recording sensitive data
- Policy enforcement requiring prepared statements in supported database-access libraries
