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-2026-77791 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- tomcat (Bitnami): affected from 8.5.88; fixed in 9.0.45, 9.0.122, 10.1.60, 11.0.26\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-2026-77791/ (Markdown: https://insights.sbomify.com/CVE-2026-77791/index.md)","id":"CVE-2026-77791","markdown":"https://insights.sbomify.com/CVE-2026-77791/index.md","name":"CVE-2026-77791","record":{"aliases":["BIT-tomcat-2026-77791","DEBIAN-CVE-2026-77791","GHSA-9cg7-2q68-g3mq","MINI-8mc6-r2g9-4w7f","MINI-qxf3-jq24-6gv4","MINI-rx28-m2q3-cx5h","UBUNTU-CVE-2026-77791"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Tomcat","requires_auth":"none","summary":"Attackers can cause a denial of service in Apache Tomcat by triggering a busy wait during WebSocket close messages.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Uncontrolled Resource Consumption vulnerability in Apache Tomcat during sending of WebSocket close message enabled a DoS attack.\n\nThis issue affects Apache Tomcat: from 11.0.0-M5 through 11.0.25, from 10.1.8 through 10.1.59, from 9.0.74 through 9.0.121.\n\nThe following versions were EOL at the time the CVE was created but are \nknown to be affected: from 8.5.88 through 8.5.100.
