CVE-2026-40827
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 high privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the _RemoveRequest function due to improper neutralization of special elements in a SQL DELETE command allowing for reading the whole database and deleting entries in a non critical table. This can result in a total loss of confidentiality and some loss of integrity.
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 confidenceAn unauthenticated SQL injection vulnerability exists in the _RemoveRequest function where improper neutralization of special elements in a SQL DELETE command allows attackers to read the entire database and delete entries from non-critical tables, resulting in total confidentiality loss and partial integrity compromise.

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 the application containing _RemoveRequest functionLocate the source code or binary that contains the _RemoveRequest function. This is typically a web application handling request/deletion operations.Affected if The application uses a _RemoveRequest function that processes DELETE operations without proper SQL sanitization
-
Check installed product versionRetrieve the version number of the affected product/application through its admin interface, about page, or by querying the binary/service.Affected if The installed version falls within any vulnerable version range for this CVE
-
Verify unauthenticated access to _RemoveRequestInspect the authentication and authorization controls around the _RemoveRequest function endpoint. Confirm whether the function can be accessed without credentials.Affected if The function is accessible without authentication (no login required)
-
Confirm DELETE request handling in _RemoveRequestReview the _RemoveRequest function code or intercept network traffic to confirm it processes DELETE commands and passes user input directly to SQL queries.Affected if The function accepts user-supplied input and incorporates it into SQL DELETE statements without parameterized queries
-
Test for SQL injection in the functionSend crafted SQL injection payloads in request parameters to the _RemoveRequest endpoint and observe if database responses are returned or if timing-based blind injection occurs.Affected if SQL injection is confirmed through unexpected database errors, data exfiltration, or time delays indicating blind injection
The environment is affected if the installed product contains a _RemoveRequest function that processes DELETE requests without authentication and uses unsanitized user input in 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 dataImplement parameterized queries (prepared statements) for all SQL commands in the _RemoveRequest function and apply proper input validation to neutralize special SQL characters.
