Guides on this site
Prevent NoSQL, LDAP, XPath and expression-language injection
SQL is not the only query language that receives user input. Stop MongoDB operator injection with type checks and $eq, escape LDAP filter values, pass XPath values as variables, and never evaluate SpEL or OGNL built from request data.
Validate input safely and prevent regex denial of service
Find and fix exponential and quadratic regex backtracking with measured examples, choose linear-time engines or timeouts, and build allowlist validation that decodes once and rejects type confusion and parameter pollution.
