Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-23918 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- apache (Bitnami): affected from 2.4.66; fixed in 2.4.67\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-2026-23918/ (Markdown: https://insights.sbomify.com/CVE-2026-23918/index.md)","id":"CVE-2026-23918","markdown":"https://insights.sbomify.com/CVE-2026-23918/index.md","name":"CVE-2026-23918","record":{"aliases":["ALPINE-CVE-2026-23918","AZL-86004","BELL-CVE-2026-23918","BIT-apache-2026-23918","CLSA-2026-1778054005","CLSA-2026-1778070287","CLSA-2026-1778107205","DEBIAN-CVE-2026-23918","GHSA-p8fm-9c82-pw4g","MINI-6g43-93qq-h8px","UBUNTU-CVE-2026-23918"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache HTTP Server","requires_auth":"low_privilege","summary":"Attackers can trigger a double free in the HTTP/2 module, potentially leading to remote code execution or denial of service on Apache HTTP Server.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"http_server","vendor":"apache"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-1341","name":"Multiple Releases of Same Resource or Handle"},{"id":"CWE-415","name":"Double Free"}],"description":"Double Free and possible RCE vulnerability in Apache HTTP Server with the HTTP/2 protocol.\n\nThis issue affects Apache HTTP Server: 2.4.66.\n\nUsers are recommended to upgrade to version 2.4.67, which fixes the issue.","ecosystems":["Bitnami"],"exploits":{"exploitdb":1,"first_seen":"2026-05-05","github_poc":15,"max_poc_stars":32,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-05-11T14:07:41Z","kind":"github_poc","ref":"https://github.com/striga-ai/CVE-2026-23918","stars":32,"title":"Double-free in Apache httpd mod_http2 stream cleanup leading to pre-auth RCE."},{"date":"2026-05-06T13:00:15Z","kind":"github_poc","ref":"https://github.com/xeloxa/CVE-2026-23918-Apache-H2-PoC","stars":23,"title":"Proof-of-Concept exploit for CVE-2026-23918 (Apache mod_http2 double-free).
