Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-42528 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-2026-42528/ (Markdown: https://insights.sbomify.com/CVE-2026-42528/index.md)","id":"CVE-2026-42528","markdown":"https://insights.sbomify.com/CVE-2026-42528/index.md","name":"CVE-2026-42528","record":{"aliases":["ALPINE-CVE-2026-42528","AZL-106773","BELL-CVE-2026-42528","BIT-apache-2026-42528","DEBIAN-CVE-2026-42528","ECHO-5aa6-ecfa-0fc3","GHSA-fvh8-pv2h-6xr6","MINI-cff8-vp8c-gfmc","UBUNTU-CVE-2026-42528"],"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":"low_privilege","summary":"An attacker with WebDAV lock permissions can crash Apache server child processes due to a memory calculation bug in mod_dav.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"http_server","vendor":"apache"}],"cvss":{"score":4.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-789","name":"Memory Allocation with Excessive Size Value"}],"description":"A memory calculation bug in mod_dav in Apache httpd 2.4.67 and earlier allows an attacker with permission to create WebDAV locks to crash server child processes.\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_dav shared lock overflow","id":"CVE-2026-42528","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"apache:http_server","products":["apache:http_server"],"type":"integer_overflow","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"NGINX Open-Source ngx_http_v3_module vulnerability","id":"CVE-2026-42530"},"packages":[{"ecosystem":"Bitnami","fixed":["2.4.69"],"introduced":["2.4.0"],"last_affected":[],"package":"apache","purl":"pkg:bitnami/apache","source":"BIT-apache-2026-42528"}],"prev":{"headline":"Apache Camel: Permissive default ObjectInputFilter pattern admits java.net.** and enables DNS-based information disclosure","id":"CVE-2026-42527"},"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-01","vendors":["Apache Software Foundation"]},"summary":"An attacker with WebDAV lock permissions can crash Apache server child processes due to a memory calculation bug in mod_dav.","url":"https://insights.sbomify.com/CVE-2026-42528/"}
