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-2026-41293 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 10.1.55\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 10.1.0-M1; fixed in 10.1.55\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 11.0.0-M1; fixed in 11.0.22\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 11.0.0-M1; fixed in 11.0.22\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 8.5.0; fixed in 9.0.118\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 8.5.0; fixed in 9.0.118\n- tomcat (Bitnami): affected from 10.0.0; fixed in 10.1.55, 11.0.22, 9.0.118\n- org.apache.tomcat:tomcat (Maven): affected from 10.1.0-M1; fixed in 10.1.55\n- org.apache.tomcat:tomcat (Maven): affected from 10.1.0-M1; fixed in 10.1.55\n- org.apache.tomcat:tomcat (Maven): affected from 11.0.0-M1; fixed in 11.0.22\n- org.apache.tomcat:tomcat (Maven): affected from 11.0.0-M1; fixed in 11.0.22\n- org.apache.tomcat:tomcat (Maven): affected from 8.5.0; fixed in 9.0.118\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-2026-41293/ (Markdown: https://insights.sbomify.com/CVE-2026-41293/index.md)","id":"CVE-2026-41293","markdown":"https://insights.sbomify.com/CVE-2026-41293/index.md","name":"CVE-2026-41293","record":{"aliases":["BIT-tomcat-2026-41293","CLEANSTART-2026-NC17468","CLEANSTART-2026-WT20984","CLSA-2026-1780650326","CLSA-2026-1787058472","DEBIAN-CVE-2026-41293","GHSA-r29c-68gh-xp6x","MINI-222c-wc68-4gxc","MINI-75c5-xpmc-9rf5","MINI-cxhf-q33p-qwcp","MINI-fp64-mhfv-c4v7","MINI-h28w-hf8j-8hg3","MINI-jpxw-965w-642g","MINI-r3jm-hpv5-gc73","MINI-rqp9-8q59-r25p","MINI-w9h8-5vcr-rwx8","ROOT-APP-MAVEN-CVE-2026-41293","UBUNTU-CVE-2026-41293"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Tomcat","requires_auth":"none","summary":"Apache Tomcat fails to validate HTTP/2 request headers, potentially allowing malformed requests to bypass security checks or cause unexpected behavior.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"tomcat","vendor":"apache"}],"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 Input Validation vulnerability in Apache Tomcat.\n\nThis issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.21, from 10.1.0-M1 through 10.1.54, from 9.0.0.M1 through 9.0.117, from 10.0.0-M1 through 10.0.27.\nOlder, end of support versions may also be affected.\n\nUsers are recommended to upgrade to version [FIXED_VERSION], which fixes the issue.","ecosystems":["Bitnami","Maven"],"exploits":{"exploitdb":0,"first_seen":"2026-08-06","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-08-06T05:48:01Z","kind":"github_poc","ref":"https://github.com/xiaoqiMikko/tomcat-check","stars":0,"title":"查出 Spring Boot 内嵌 Tomcat 的真实版本(pom 里没有),并对每条 2026 年 CVE 同时给出 ASF 官方评级与 GitHub 评级、触发条件、以及这条会不会进 Dependabot 告警 CVE-2026-41293"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Apache Tomcat: HTTP/2 request headers not validated","id":"CVE-2026-41293","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"apache:tomcat","products":["apache:tomcat"],"type":"other","year":"2026"},"n_packages":19,"n_references":1,"next":{"headline":"OpenClaw \u003c 2026.3.28 -
