A flaw was found in jsonwebtoken node module before 4.2.2, it is possible for an attacker to bypass verification when a token digitally signed with an asymetric key (RS/ES family) of algorithms but instead the attacker send a token digitally signed with a symmetric algorithm (HS* family) References: https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/ https://nodesecurity.io/advisories/17 https://www.timmclean.net/2015/02/25/jwt-alg-none.html Patch: https://github.com/auth0/node-jsonwebtoken/commit/1bb584bc382295eeb7ee8c4452a673a77a68b687
The fh-supercore component of Red Hat Mobile Application Platform uses nodejs-jsonwebtoken version 7.2.1 which is not affected by this vulnerablity, see: https://github.com/auth0/node-jsonwebtoken/blob/8da893ae31e0266cb9277c4b931f79375841e545/verify.js#L62
