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-2026-63686 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- apache (Bitnami): affected from 2.4.0; fixed in 2.4.69\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-2026-63686/ (Markdown: https://insights.sbomify.com/CVE-2026-63686/index.md)","id":"CVE-2026-63686","markdown":"https://insights.sbomify.com/CVE-2026-63686/index.md","name":"CVE-2026-63686","record":{"aliases":["ALPINE-CVE-2026-63686","AZL-106755","BELL-CVE-2026-63686","BIT-apache-2026-63686","CLSA-2026-1791488147","CLSA-2026-1791552137","CLSA-2026-1791552138","CLSA-2026-1791875122","CLSA-2026-1791875496","CLSA-2026-1791876624","DEBIAN-CVE-2026-63686","ECHO-10c7-2461-3c34","GHSA-h4g4-79cj-82qx","MINI-vf8h-jg4q-x5gw","ROOT-OS-DEBIAN-12-CVE-2026-63686","UBUNTU-CVE-2026-63686"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache HTTP Server","requires_auth":"none","summary":"An untrusted backend server can cause a denial of service in Apache HTTP Server via a proxied response with a failing charset conversion.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"http_server","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:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"A NULL pointer dereference in mod_xml2enc in Apache Software Foundation Apache HTTP Server before 2.4.69 on all platforms allows an untrusted backend server to cause a denial of service via a proxied response with a charset whose conversion partially succeeds then fails.\n\nUsers are recommended to upgrade to version 2.4.69, which fixes this issue.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Apache HTTP Server: mod_xml2enc crash on charset conversion failure","id":"CVE-2026-63686","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"apache:http_server","products":["apache:http_server"],"type":"null_dereference","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"Apache CXF: JwtRequestCodeFilter silently overrides outer PKCE and nonce parameters","id":"CVE-2026-63687"},"packages":[{"ecosystem":"Bitnami","fixed":["2.4.69"],"introduced":["2.4.0"],"last_affected":[],"package":"apache","purl":"pkg:bitnami/apache","source":"BIT-apache-2026-63686"}],"prev":{"headline":"Joomla Extension - regularlabs.com - Authorization bypass in DB Replacer extension","id":"CVE-2026-63685"},"products":["Apache HTTP Server"],"published":"2026-10-01","related":[{"cvss_score":9.8,"headline":"Apache HTTP Server Path Traversal","id":"CVE-2021-42013","kev_date_added":"2021-11-03","published":"2021-10-07"},{"cvss_score":9.1,"headline":"Apache HTTP Server Improper Escaping of Output","id":"CVE-2024-38475","kev_date_added":"2025-05-01","published":"2024-07-01"},{"cvss_score":9,"headline":"Apache HTTP Server-Side Request Forgery (SSRF)","id":"CVE-2021-40438","kev_date_added":"2021-12-01","published":"2021-09-16"},{"cvss_score":7.8,"headline":"Apache HTTP Server Privilege Escalation","id":"CVE-2019-0211","kev_date_added":"2021-11-03","published":"2019-04-08"},{"cvss_score":7.5,"headline":"Apache HTTP Server Path Traversal","id":"CVE-2021-41773","kev_date_added":"2021-11-03","published":"2021-10-05"},{"cvss_score":10,"headline":"Use after free in n/a","id":"CVE-2010-0425","kev_date_added":null,"published":"2010-03-05"},{"cvss_score":10,"headline":"Auth bypass in n/a","id":"CVE-2005-2700","kev_date_added":null,"published":"2005-09-06"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-10-01","vendors":["Apache Software Foundation"]},"summary":"An untrusted backend server can cause a denial of service in Apache HTTP Server via a proxied response with a failing charset conversion.","url":"https://insights.sbomify.com/CVE-2026-63686/"}
