VCID-b9dd-q5n1-3fcs Aliases: CVE-2026-33209 GHSA-762r-27w2-q22j	Avo has a XSS vulnerability on `return_to` param ## Description A reflected cross-site scripting (XSS) vulnerability exists in the `return_to` query parameter used in the avo interface. An attacker can craft a malicious URL that injects arbitrary JavaScript, which is executed when he clicks a dynamically generated navigation button. ## Impact This vulnerability may allow execution of arbitrary JavaScript in the context of the application. Impact varies depending on deployment: - In unauthenticated setups: exploitable via crafted links sent to users. - In authenticated setups: limited to authenticated users and requires interaction.	3.30.3 Affected by 0 other vulnerabilities.
VCID-c3rt-5bx5-p7e5 Aliases: CVE-2024-22411 GHSA-g8vp-2v5p-9qfh	Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') Avo is a framework to create admin panels for Ruby on Rails apps. In Avo 3 pre12 any HTML inside text that is passed to `error` or `succeed` in an `Avo::BaseAction` subclass will be rendered directly without sanitization in the toast/notification that appears in the UI on Action completion. A malicious user could exploit this vulnerability to trigger a cross site scripting attack on an unsuspecting user. This issue has been addressed in the 3.0.0 release of Avo. Users are advised to upgrade.	3.0.2 Affected by 3 other vulnerabilities.

VCID-w2bm-9jh8-6yc6 Aliases: CVE-2024-22191 GHSA-ghjv-mh6x-7q6h	Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') Avo is a framework to create admin panels for Ruby on Rails apps. A stored cross-site scripting (XSS) vulnerability was found in the key_value field of Avo v3.2.3. This vulnerability could allow an attacker to execute arbitrary JavaScript code in the victim's browser. The value of the key_value 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 could be used to steal sensitive information from victims that could be used to hijack victims' accounts or redirect them to malicious websites. Avo 3.2.4 includes a fix for this issue. Users are advised to upgrade.	3.2.4 Affected by 0 other vulnerabilities.
