Crate wafrift_grammar 

wafrift-grammar — Grammar-aware payload mutation engine.

Understands the semantics of SQL, XSS, CMD, LDAP, SSRF, path traversal, and template injection payloads. Generates semantically equivalent variants that bypass regex-based WAF rules.

Examples

Classify a payload to its injection family, then mutate it into semantically-equivalent variants:

use wafrift_grammar::{PayloadType, classify, mutate};

let p = "' OR 1=1 --";
assert_eq!(classify(p), PayloadType::Sql);

let variants = mutate(p, 5);
assert!(!variants.is_empty(), "SQL payload must yield mutations");
assert!(variants.len() <= 5, "max_mutations is honoured");

Force a specific grammar to mutate against (useful when the classifier is ambiguous):

use wafrift_grammar::{PayloadType, mutate_as};

let xss = mutate_as("<script>alert(1)</script>", PayloadType::Xss, 3);
assert!(!xss.is_empty());
assert!(xss.len() <= 3);
