Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-90821 in the wild and no public exploit code.\n\nAffected product: Arcadia Technology, LLC Crafty Controller. 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-2026-90821/ (Markdown: https://insights.sbomify.com/CVE-2026-90821/index.md)","id":"CVE-2026-90821","markdown":"https://insights.sbomify.com/CVE-2026-90821/index.md","name":"CVE-2026-90821","record":{"aliases":["GHSA-v36h-wgjh-vc9p"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Crafty Controller","requires_auth":"low_privilege","summary":"Remote authenticated attackers can execute stored XSS via malicious Webhook URL input in Crafty Controller, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitLab","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"An input neutralization vulnerability in the Webhook URL form field component of Crafty Controller allows a remote, authenticated attacker to perform stored XSS via malicious form input","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Crafty Controller","id":"CVE-2026-90821","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in IPVPN","id":"CVE-2026-90822"},"packages":[],"prev":{"headline":"Missing authorization in a2a-java","id":"CVE-2026-90820"},"products":["Crafty Controller"],"published":"2026-10-16","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":"2026-10-16","vendors":["Arcadia Technology, LLC"]},"summary":"Remote authenticated attackers can execute stored XSS via malicious Webhook URL input in Crafty Controller, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2026-90821/"}
