Description Guilherme de Almeida Suckevicz 2020-01-10 20:34:15 UTC
Versions of handlebars prior to 4.3.0 are vulnerable to Prototype Pollution leading to Remote Code Execution. Templates may alter an Object's __proto__ and __defineGetter__ properties, which may allow an attacker to execute arbitrary code through crafted payloads.

Comment 2 Parag Nemade 2020-01-13 06:29:50 UTC
i really wonder about CVE bugs getting reported since a year for various packages related to me. First they got reported then priority set low then discovered not present in one by one distribution and then get closed.....

Comment 3 Jason Shepherd 2020-01-14 07:09:14 UTC
While OpenShift Container Platform (OCP) contains the affected nodejs-handlebars code, it's added as a dependency of Kibana 5. Similar issue about prototype pollution [1] have been fixed, but no known attack vector was found, so we're rating this issue as Low for OCP.

Comment 5 Jason Shepherd 2020-01-14 07:13:10 UTC
While Red Hat Quay declares a dependency on nodejs-handlebars, it doesn't appear to be used in the code. This issue might be fixed in a future update.

Comment 7 Jason Shepherd 2021-05-04 00:21:11 UTC
Statement:

Red Hat Quay includes Handlebars.js as a development dependency. It does not use Handlebars.js at runtime to process templates so have been given a low impact rating.
