…-2026-01)
Hardening complet suite à la review v0.11.2 du chercheur (Maxim Yakovlev) :
- constant-folding des clés computed statiquement résolubles
('con'+'structor' -> bloqué) ;
- whitelist étendue à toutes les libs du scope eval (dotProp, cheerio,
sanitizeHtml, removeMarkdown, decodeUnicode) ;
- LIB_FORBIDDEN_METHODS (blacklist) supprimé -> modèle 100 % whitelist ;
- objets produits whitelistés (PRODUCED_WHITELISTS + inférence de type
d'appel exprType) : dayjs/moment/cheerio/crypto-hash/Buffer.from ;
- JS intrinsics en whitelist stricte : Reflect, Proxy, Object.getPrototypeOf,
getOwnPropertyDescriptor, defineProperty, setPrototypeOf bloqués
(vecteur introspection argument-string fermé) ;
- sanitizeValue dans runEvalInRemote (avant sérialisation) + contrat
documenté dans evalWorker.js/secureContext.js ;
- raw-eval ÉLIMINÉ : evalWorker.js/runEvalInWorker/workerGlobals.js engine
supprimés -> l'engine n'a plus aucune évaluation interne, seul chemin =
runEvalInRemote (HTTP signé -> eval-service). Tests unitaires = logique du
container (secureContext.js de l'eval-service) ;
- code mort retiré : escapeString/resolveString/parseAndResolveString +
unicode-encode (engine + eval-service) ;
- advisory SB-RCE-2026-01 mise à jour (correctifs + résiduel documenté
comme non-vulnérabilité).
