An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-81571 in the wild and no public exploit code.\n\nAffected product: Unknown Brave. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-81571/ (Markdown: https://insights.sbomify.com/CVE-2026-81571/index.md)","id":"CVE-2026-81571","markdown":"https://insights.sbomify.com/CVE-2026-81571/index.md","name":"CVE-2026-81571","record":{"aliases":["GHSA-mhhc-49mj-h4mm"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary shortcodes server-side via a URL parameter, potentially leading to code execution.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"The Brave WordPress plugin before 0.8.8 does not prevent a URL parameter used to pre-fill a form field from being passed to WordPress's shortcode engine, allowing unauthenticated attackers to have arbitrary shortcodes registered on the site executed server-side.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Brave Popup Builder \u003c 0.8.8 - Unauthenticated Arbitrary Shortcode Execution via UTM Parameter","id":"CVE-2026-81571","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Local Privilege Escalation in CodeMeter Runtime on Windows","id":"CVE-2026-81572"},"packages":[],"prev":{"headline":"Apache DolphinScheduler: Improper Authorization in Sub-Workflow Tasks Allows Unauthorized Workflow Execution","id":"CVE-2026-81569"},"products":["Brave"],"published":"2026-09-02","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-02","vendors":["Unknown"]},"summary":"Unauthenticated attackers can execute arbitrary shortcodes server-side via a URL parameter, potentially leading to code execution.","url":"https://insights.sbomify.com/CVE-2026-81571/"}
