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-2026-3204 in the wild and no public exploit code.\n\nAffected product: Devolutions Devolutions Server. 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-2026-3204/ (Markdown: https://insights.sbomify.com/CVE-2026-3204/index.md)","id":"CVE-2026-3204","markdown":"https://insights.sbomify.com/CVE-2026-3204/index.md","name":"CVE-2026-3204","record":{"aliases":["GHSA-jq3r-jmv6-j5m4"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Devolutions Server","requires_auth":"none","summary":"Remote attackers can spoof displayed error messages in Devolutions Server via crafted URLs, potentially misleading users.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"DEVOLUTIONS","cpe":[{"product":"devolutions_server","vendor":"devolutions"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper\n input validation in the error message page in Devolutions Server 2025.3.16 and earlier allows remote attackers to spoof the displayed error message via a specially crafted URL.","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":"Cross-site scripting in Server","id":"CVE-2026-3204","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"devolutions:devolutions_server","products":["devolutions:devolutions_server"],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Improper management of context cancelations","id":"CVE-2026-3206"},"packages":[],"prev":{"headline":"Buffer Over-read in Wireshark","id":"CVE-2026-3203"},"products":["Server"],"published":"2026-03-03","related":[{"cvss_score":9.8,"headline":"Business logic in Server","id":"CVE-2026-3130","kev_date_added":null,"published":"2026-03-03"},{"cvss_score":9.8,"headline":"Auth bypass in Server","id":"CVE-2026-3224","kev_date_added":null,"published":"2026-03-03"},{"cvss_score":9.8,"headline":"SQL injection in Server","id":"CVE-2026-0610","kev_date_added":null,"published":"2026-01-19"},{"cvss_score":9.8,"headline":"Missing authorization in Server","id":"CVE-2024-2921","kev_date_added":null,"published":"2024-03-26"},{"cvss_score":9.5,"headline":"Hardcoded credentials in Server","id":"CVE-2025-6523","kev_date_added":null,"published":"2025-07-22"},{"cvss_score":9.1,"headline":"Missing authorization in n/a","id":"CVE-2021-23921","kev_date_added":null,"published":"2021-04-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-04","vendors":["Devolutions"]},"summary":"Remote attackers can spoof displayed error messages in Devolutions Server via crafted URLs, potentially misleading users.","url":"https://insights.sbomify.com/CVE-2026-3204/"}
