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-2026-24880 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 10.1.0-M1; fixed in 10.1.52\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 10.1.0-M1; fixed in 10.1.52\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 11.0.0-M1; fixed in 11.0.20\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 11.0.0-M1; fixed in 11.0.20\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 7.0.0; fixed in 9.0.116\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 7.0.0; fixed in 9.0.116\n- tomcat (Bitnami): affected all versions; fixed in 9.0.116, 10.1.53, 11.0.20\n- org.apache.tomcat:tomcat-coyote (Maven): affected from 10.1.0-M1; fixed in 10.1.52\n- org.apache.tomcat:tomcat-coyote (Maven): affected from 10.1.0-M1; fixed in 10.1.52\n- org.apache.tomcat:tomcat-coyote (Maven): affected from 11.0.0-M1; fixed in 11.0.20\n- org.apache.tomcat:tomcat-coyote (Maven): affected from 11.0.0-M1; fixed in 11.0.20\n- org.apache.tomcat:tomcat-coyote (Maven): affected from 7.0.0; fixed in 9.0.116\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-2026-24880/ (Markdown: https://insights.sbomify.com/CVE-2026-24880/index.md)","id":"CVE-2026-24880","markdown":"https://insights.sbomify.com/CVE-2026-24880/index.md","name":"CVE-2026-24880","record":{"aliases":["BIT-tomcat-2026-24880","CLEANSTART-2026-PK48524","CLSA-2026-1778546710","CLSA-2026-1778633134","DEBIAN-CVE-2026-24880","GHSA-563x-q5rq-57qp","MINI-2ccr-f9x5-89jq","MINI-3638-p33p-666c","MINI-36fj-mw96-vrqf","MINI-5cg6-jqch-vrjx","MINI-78fr-p4hp-jcxj","MINI-rqqj-726r-hmj6","ROOT-APP-MAVEN-CVE-2026-24880","UBUNTU-CVE-2026-24880"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Tomcat","requires_auth":"none","summary":"Attackers can exploit HTTP request smuggling via invalid chunk extensions in Apache Tomcat, potentially bypassing security controls.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"tomcat","vendor":"apache"}],"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:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-444","name":"Inconsistent Interpretation of HTTP Requests"}],"description":"Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') vulnerability in Apache Tomcat via invalid chunk extension.\n\nThis issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.18, from 10.1.0-M1 through 10.1.52, from 9.0.0.M1 through 9.0.115, from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109.\nOther, unsupported versions may also be affected.\n\nUsers are recommended to upgrade to version 11.0.20, 10.1.52 or 9.0.116, which fix the issue.","ecosystems":["Bitnami","Maven"],"exploits":{"exploitdb":0,"first_seen":"2026-09-01","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-01T05:50:23Z","kind":"github_poc","ref":"https://github.com/xiaoqiMikko/tomcat-line-check","stars":0,"title":"CVE-2026-24880: does Apache's upgrade advice actually apply to your Tomcat?
