Access Control Through Unauthorized Execution of Arbitrary Action Classes Across Resources\n### Summary\n\nA critical Broken Access Control vulnerability was identified in the\n`ActionsController` of the Avo framework (v3.x). Due to insecure\naction lookup logic, an authenticated user can execute any Action\nclass (descendants of `Avo::BaseAction`) on any resource, even if\nthe action is not registered for that specific resource. This leads\nto Privilege Escalation and unauthorized data manipulation across\nthe entire application.\n\n### Details\n\nThe vulnerability exists in the `action_class` method within\n`app/controllers/avo/actions_controller.rb`.\n\n#### Vulnerable Code\n\n```ruby\ndef action_class\n  # It searches through ALL descendants of BaseAction without\n  #    resource validation.\n  Avo::BaseAction.descendants.find do |action|\n    action.to_s == params[:action_id]\n  end\nend\n```\n\nThe controller identifies the action class to execute solely based\non the `params[:action_id]` by searching through all `BaseAction`\ndescendants. It fails to verify whether the requested action is\nactually permitted or registered for the resource context specified\nin the request URL (e.g., `/admin/resources/posts/actions`).\n\nConsequently, an attacker can invoke sensitive actions (e.g.,\n`Avo::Actions::ToggleAdmin`) through an unrelated resource endpoint\n(e.g., `Post`), bypassing the intended resource-action mapping.\n\n### Impact\n\nThis flaw results in significant security risks:\n\n- **Privilege Escalation:** An authenticated user with low privileges\n  can execute administrative actions (like toggling admin roles) to\n  escalate their own or others' permissions.\n- **Unauthorized Operations:** Actions designed for restricted\n  resources can be triggered against any record ID in the database.\n- **Data Integrity Compromise:** Attackers can perform unauthorized\n  destructive operations (e.g., Delete, Archive, or Update) on records\n  they should not have access to.\n\n### CREDIT\n\nIllunight","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-42205","reference_id":"","reference_type":"","scores":[{"value":"0.00044","scoring_system":"epss","scoring_elements":"0.13812","published_at":"2026-06-05T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-42205"},{"reference_url":"https://github.com/avo-hq/avo","reference_id":"","reference_type":"","scores":[{"value":"8.8","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/avo-hq/avo"},{"reference_url":"https://github.com/avo-hq/avo/releases/tag/v3.31.2","reference_id":"","reference_type":"","scores":[{"value":"8.8","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track*","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:T/P:M/B:A/M:M/D:R/2026-05-12T12:51:27Z/"}],"url":"https://github.com/avo-hq/avo/releases/tag/v3.31.2"},{"reference_url":"https://github.com/avo-hq/avo/security/advisories/GHSA-qc5p-3mg5-9fh8","reference_id":"","reference_type":"","scores":[{"value":"8.8","scoring_system":"cvssv3","scoring_elements":""},{"value":"8.8","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track*","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:T/P:M/B:A/M:M/D:R/2026-05-12T12:51:27Z/"}],"url":"https://github.com/avo-hq/avo/security/advisories/GHSA-qc5p-3mg5-9fh8"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42205","reference_id":"","reference_type":"","scores":[{"value":"8.8","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42205"},{"reference_url":"https://github.com/advisories/GHSA-qc5p-3mg5-9fh8","reference_id":"GHSA-qc5p-3mg5-9fh8","reference_type":"","scores":[],"url":"https://github.com/advisories/GHSA-qc5p-3mg5-9fh8"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/110632?format=json","purl":"pkg:gem/avo@3.31.2","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:gem/avo@3.31.2"}],"aliases":["CVE-2026-42205","GHSA-qc5p-3mg5-9fh8"],"risk_score":null,"exploitability":null,"weighted_severity":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-u68f-bw9j-dyh8"}],"fixing_vulnerabilities":[],"risk_score":"3.1","resource_url":"http://public2.vulnerablecode.io/packages/pkg:gem/avo@3.17.1"}
