| VCID-f5rz-dtuy-bbgx | Prototype Pollution in handlebars Versions of `handlebars` prior to 3.0.8 or 4.5.3 are vulnerable to prototype pollution. It is possible to add or modify properties to the Object prototype through a malicious template. This may allow attackers to crash the application or execute Arbitrary Code in specific conditions. ## Recommendation Upgrade to version 3.0.8, 4.5.3 or later. |

| VCID-kyw8-zzpv-67c1 | Prototype Pollution in handlebars Versions of `handlebars` prior to 3.0.8 or 4.3.0 are vulnerable to Prototype Pollution leading to Remote Code Execution. Templates may alter an Objects' `__proto__` and `__defineGetter__` properties, which may allow an attacker to execute arbitrary code through crafted payloads. ## Recommendation Upgrade to version 3.0.8, 4.3.0 or later. |
CVE-2019-19919
GHSA-w457-6q6x-cgp9 |
| VCID-wkcp-xswz-t3d9 | Arbitrary Code Execution in handlebars Versions of `handlebars` prior to 3.0.8 or 4.5.3 are vulnerable to Arbitrary Code Execution. The package's lookup helper fails to properly validate templates, allowing attackers to submit templates that execute arbitrary JavaScript in the system. It is due to an incomplete fix for a [previous issue](https://www.npmjs.com/advisories/1316). This vulnerability can be used to run arbitrary code in a server processing Handlebars templates or on a victim's browser (effectively serving as Cross-Site Scripting). ## Recommendation Upgrade to version 3.0.8, 4.5.3 or later. |

| VCID-x86m-h2at-37am | Arbitrary Code Execution in Handlebars Handlebars before 3.0.8 and 4.x before 4.5.3 is vulnerable to Arbitrary Code Execution. The lookup helper fails to properly validate templates, allowing attackers to submit templates that execute arbitrary JavaScript. This can be used to run arbitrary code on a server processing Handlebars templates or in a victim's browser (effectively serving as XSS). |
CVE-2019-20920
GHSA-3cqr-58rm-57f8 |
| VCID-xcuy-x2xk-6ya9 | Arbitrary Code Execution in handlebars Versions of `handlebars` prior to 3.0.8 or 4.5.2 are vulnerable to Arbitrary Code Execution. The package's lookup helper fails to properly validate templates, allowing attackers to submit templates that execute arbitrary JavaScript in the system. It can be used to run arbitrary code in a server processing Handlebars templates or on a victim's browser (effectively serving as Cross-Site Scripting). The following template can be used to demonstrate the vulnerability: ```{{#with "constructor"}} {{#with split as |a|}} {{pop (push "alert('Vulnerable Handlebars JS');")}} {{#with (concat (lookup join (slice 0 1)))}} {{#each (slice 2 3)}} {{#with (apply 0 a)}} {{.}} {{/with}} {{/each}} {{/with}} {{/with}} {{/with}}``` ## Recommendation Upgrade to version 3.0.8, 4.5.2 or later. |
