This affects the package @strikeentco/set before 1.0.2. It allows an attacker to cause a denial of service and may lead to remote code execution. **Note:** This vulnerability derives from an incomplete fix in https://security.snyk.io/vuln/SNYK-JS-STRIKEENTCOSET-1038821

Prototype Pollution in GitHub repository mastodon/mastodon prior to 3.5.0.

The package keyget from 0.0.0 are vulnerable to Prototype Pollution via the methods set, push, and at which could allow an attacker to cause a denial of service and may lead to remote code execution. **Note:** This vulnerability derives from an incomplete fix to [CVE-2020-28272](https://security.snyk.io/vuln/SNYK-JS-KEYGET-1048048)

The package bmoor before 0.10.1 are vulnerable to Prototype Pollution due to missing sanitization in set function. **Note:** This vulnerability derives from an incomplete fix in [CVE-2020-7736](https://security.snyk.io/vuln/SNYK-JS-BMOOR-598664)

The package min-dash before 3.8.1 are vulnerable to Prototype Pollution via the set method due to missing enforcement of key types.

The package cached-path-relative before 1.1.0 are vulnerable to Prototype Pollution via the cache variable that is set as {} instead of Object.create(null) in the cachedPathRelative function, which allows access to the parent prototype properties when the object is used to create the cached relative path. When using the origin path as __proto__, the attribute of the object is accessed instead of a path. **Note:** This vulnerability derives from an incomplete fix in https://security.snyk.io/vuln/SNYK-JS-CACHEDPATHRELATIVE-72573

All versions of package realms-shim are vulnerable to Sandbox Bypass via a Prototype Pollution attack vector.

The package extend2 before 1.0.1 are vulnerable to Prototype Pollution via the extend function due to unsafe recursive merge.

All versions of package realms-shim are vulnerable to Sandbox Bypass via a Prototype Pollution attack vector.

OroPlatform is a PHP Business Application Platform. In affected versions by sending a specially crafted request, an attacker could inject properties into existing JavaScript language construct prototypes, such as objects. Later this injection may lead to JS code execution by libraries that are vulnerable to Prototype Pollution. This issue has been patched in version 4.2.8. Users unable to upgrade may configure a firewall to drop requests containing next strings: `__proto__` , `constructor[prototype]`, and `constructor.prototype` to mitigate this issue.
