CVE-2024-22191 is a high-severity cross-site scripting (XSS) vulnerability in avo (rubygems), affecting versions >= 3.0.0.beta1, <= 3.2.3. It is fixed in 3.2.4, 2.47.0.
Summary A stored cross-site scripting (XSS) vulnerability was found in the keyvalue field of Avo v3.2.3. This vulnerability could allow an attacker to execute arbitrary JavaScript code in the victim's browser. Details The value of the keyvalue is inserted directly into the HTML code. In the current version of Avo (possibly also older versions), the value is not properly sanitized before it is inserted into the HTML code. This vulnerability can be exploited by an attacker to inject malicious JavaScript code into the keyvalue field. When a victim views the page containing the malicious code, the code will be executed in their browser. In avo/fields/common/keyvaluecomponent.html.erb the value is taken in lines 38 and 49 and seems to be interpreted directly as html in lines 44 and 55. PoC To reproduce the vulnerability, follow these steps: Edit an entry with a keyvalue field. Enter the following payload into the value field: POC\"> <script>alert( 'XSS in keyvalue' );</script> <strong>Outside-tag</strong Save the entry. Go to the index page and click on the eye icon next to the entry. The malicious JavaScript code will be executed and an alert box will be displayed. On the show and edit page the alert seems not to pop up, but the strong tag breaks out of the expected html tag_ Impact This vulnerability could be used to steal sensitive information from victims that could be used to hijack victims' accounts or redirect them to malicious websites.
Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.
CVE-2024-22191 has a CVSS score of 7.3 (High). The vector is network-reachable, low privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment.
A fixed version is available (3.2.4, 2.47.0). Upgrading removes the vulnerable code path.

Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter instead of chasing every advisory.

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
