CVE-2026-2113

Least functionality restricts the file types and automatic processing capabilities the system will accept.

Requiring documented development standards and tools can embed input-validation practices into the engineering process.

Engineering principles such as safe deserialization and input sanitization structurally prevent the weakness from being introduced.

Hardened configuration baselines can enforce allowed file types and processing rules.

Secure-coding guidelines and mandatory security testing (including code scans) compel developers to validate and sanitize inputs at design and implementation time, lowering the incidence of malformed or malicious data reaching downstream components.

Mandating input controls that include integrity checks and input validation ensures that untrusted data is examined before use, blocking the root cause of many injection and malformed-data weaknesses.

Security-by-design principles explicitly call for data validation and sanitization at every layer, reducing the chance that malformed or malicious input will be processed without scrutiny.

Requiring language-specific secure coding standards, peer review, SAST and documented mitigation of common programming errors forces validation of all inputs before they are trusted.

Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.
