It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-32777 in the wild and no public exploit code.\n\nAffected product: Libexpat Project Libexpat. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-32777/ (Markdown: https://insights.sbomify.com/CVE-2026-32777/index.md)","id":"CVE-2026-32777","markdown":"https://insights.sbomify.com/CVE-2026-32777/index.md","name":"CVE-2026-32777","record":{"aliases":["ALPINE-CVE-2026-32777","AZL-79859","BELL-CVE-2026-32777","DEBIAN-CVE-2026-32777","ECHO-1645-a8de-a79e","GHSA-9rpf-mhcj-gv7r","JLSEC-2026-382","ROOT-OS-DEBIAN-11-CVE-2026-32777","UBUNTU-CVE-2026-32777"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"XML parsing library","requires_auth":"none","summary":"An attacker can cause a denial of service via an infinite loop in libexpat when parsing malicious DTD content.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libexpat","vendor":"libexpat_project"}],"cvss":{"score":4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"libexpat before 2.7.5 allows an infinite loop while parsing DTD content.","ecosystems":[],"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":"Denial of service in libexpat","id":"CVE-2026-32777","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"libexpat_project:libexpat","products":["libexpat_project:libexpat"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Null dereference in libexpat","id":"CVE-2026-32778"},"packages":[],"prev":{"headline":"Null dereference in libexpat","id":"CVE-2026-32776"},"products":["libexpat"],"published":"2026-03-16","related":[{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2024-45490","kev_date_added":null,"published":"2024-08-30"},{"cvss_score":8.7,"headline":"Expat Denial of Service via storeAtts() Quadratic Complexity","id":"CVE-2026-66046","kev_date_added":null,"published":"2026-08-18"},{"cvss_score":8.1,"headline":"Integer overflow in n/a","id":"CVE-2021-46143","kev_date_added":null,"published":"2022-01-06"},{"cvss_score":7.8,"headline":"Privilege escalation in n/a","id":"CVE-2017-11742","kev_date_added":null,"published":"2017-07-30"},{"cvss_score":7.5,"headline":"Denial of service in libexpat","id":"CVE-2025-59375","kev_date_added":null,"published":"2025-09-15"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2023-52425","kev_date_added":null,"published":"2024-02-04"},{"cvss_score":7.3,"headline":"Integer overflow in n/a","id":"CVE-2024-45491","kev_date_added":null,"published":"2024-08-30"}],"sources":[{"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":"2026-10-15","vendors":["libexpat project"]},"summary":"An attacker can cause a denial of service via an infinite loop in libexpat when parsing malicious DTD content.","url":"https://insights.sbomify.com/CVE-2026-32777/"}
