Strikingly · Strikingly Cms · CVE-2023-2582
**Name of the Vulnerable Software and Affected Versions**
Strikingly CMS (affected versions not specified)
**Description**
A prototype pollution issue exists in Strikingly CMS, potentially leading to reflected cross-site scripting (XSS) in affected applications and sites. This occurs because the Strikingly JavaScript library's parsing of the URL fragment allows access to the ` proto ` or constructor properties and the Object prototype. An attacker could exploit this by convincing a victim to visit a specially crafted link, leveraging an embedded gadget like jQuery to achieve arbitrary JavaScript execution in the context of the user's browser.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
