Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-66422 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- tomcat (Bitnami): affected from 7.0.97; fixed in 9.0.121, 10.1.58, 11.0.25\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-2026-66422/ (Markdown: https://insights.sbomify.com/CVE-2026-66422/index.md)","id":"CVE-2026-66422","markdown":"https://insights.sbomify.com/CVE-2026-66422/index.md","name":"CVE-2026-66422","record":{"aliases":["BIT-tomcat-2026-66422","DEBIAN-CVE-2026-66422","GHSA-w3xg-786f-g788","MINI-4qph-4xgc-cf9h","MINI-hv9x-wfmc-wwx4","MINI-w3h8-739q-j6mh","UBUNTU-CVE-2026-66422"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Tomcat","requires_auth":"low_privilege","summary":"Attackers can bypass declarative role constraints in Apache Tomcat by exploiting improper handling of security-role-ref definitions, gaining unauthorized access.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"tomcat","vendor":"apache"}],"cvss":{"score":8.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-285","name":"Improper Authorization"}],"description":"Improper Authorization vulnerability in Apache Tomcat cause by security-role-ref definitions being incorrectly used as role aliases within the Realm in additional to the correct usage with Request.isUserInRole().\n\nThis issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.24, from 10.1.0-M1 through 10.1.57, from 9.0.25 through 9.0.120.\n\nThe following versions were EOL at the time the CVE was created but are \nknown to be affected: from 8.5.46 through 8.5.100, from 7.0.97 through 7.0.109.
