CVE-2026-55518CRITICAL | Avo: Missing Authorization in Avo Association Attach Endpoint Allows Unauthorized Relationship Manipulation and Privilege EscalationAvo is a framework to create admin panels for Ruby on Rails apps. Prior to 3.32.1 and 4.0.0.beta.51, Avo's association attach workflow checks attach_<association>? in the UI and GET /resources/:resource/:id/:related/new path, but the actual write endpoint, POST /resources/:resource/:id/:related, does not run the same authorization check before mutating the association through Avo::AssociationsController#create. An authenticated low-privileged Avo user can bypass hidden or disabled attach control… | CVSS9.6v3.1 | EPSS0.331% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
Avo: Direct attachment upload endpoint lacks upload authorization and bypasses field-level upload policy### Summary Avo's direct attachment upload endpoint lacks server-side upload authorization and bypasses the documented field-level upload policy methods such as `upload_{FIELD_ID}?`. An authenticated Avo user who can reach the Avo attachment upload endpoint can replace or add attachment content, including binary content, filename, and content-type metadata, on a resolved record even when both `update?` and `upload_<field>?` policies deny the operation. This primarily affects multi-role Avo Pr… | CVSS-v3.1 | EPSS- | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX | |
CVE-2026-42205HIGH | Avo: Broken Access Control: Unauthorized Execution of Arbitrary Action Classes Across ResourcesAvo is a framework to create admin panels for Ruby on Rails apps. Prior to version 3.31.2, a broken access control vulnerability was identified in the ActionsController of the Avo framework. Due to insecure action lookup logic, an authenticated user can execute any Action class (descendants of Avo::BaseAction) on any resource, even if the action is not registered for that specific resource. This leads to Privilege Escalation and unauthorized data manipulation across the entire application.

CVE-2026-33209MEDIUM | Avo has a XSS vulnerability on `return_to` paramAvo is a framework to create admin panels for Ruby on Rails apps. Prior to version 3.30.3, 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. This issue has been patched in version 3.30.3.

CVE-2024-22411MEDIUM | Cross site scripting in Action messages on AvoAvo 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 3.3.0 and 2.47.0 releases of Avo. Users are advised to… CWE-79Jan 16, 2024 | CVSS6.5v3.1 | EPSS0.71% | PoCs1 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2024-22191HIGH | Stored cross-site scripting (XSS) in `key_value` field in AvoAvo 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 and v2.46.0. 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 vulner… CWE-79Jan 16, 2024 | CVSS7.3v3.1 | EPSS0.745% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2023-34102HIGH | Possible unsafe reflection / partial denial of service in avoAvo is an open source ruby on rails admin panel creation framework. The polymorphic field type stores the classes to operate on when updating a record with user input, and does not validate them in the back end. This can lead to unexpected behavior, remote code execution, or application crashes when viewing a manipulated record. This issue has been addressed in commit `ec117882d` which is expected to be included in subsequent releases. Users are advised to limit access to untrusted users until a… | CVSS8.3v3.1 | EPSS1.61% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2023-34103HIGH | Stored XSS (Cross Site Scripting) in html content based fields of avoAvo is an open source ruby on rails admin panel creation framework. In affected versions some avo fields are vulnerable to Cross Site Scripting (XSS) when rendering html based content. Attackers do need form edit privilege in order to successfully exploit this vulnerability, but the results are stored and no specific timing is required. This issue has been addressed in commit `7891c01e` which is expected to be included in the next release of avo. Users are advised to configure CSP headers for th… CWE-79Jun 5, 2023 | CVSS7.3v3.1 | EPSS0.563% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
