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-2026-72522 in the wild and no public exploit code.\n\nAffected product: 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-2026-72522/ (Markdown: https://insights.sbomify.com/CVE-2026-72522/index.md)","id":"CVE-2026-72522","markdown":"https://insights.sbomify.com/CVE-2026-72522/index.md","name":"CVE-2026-72522","record":{"aliases":["AZL-94698","BELL-CVE-2026-72522","CLSA-2026-1786976393","DEBIAN-CVE-2026-72522","ECHO-de7d-deea-1f3e","GHSA-v867-w97p-3vx2","OESA-2026-3403","OESA-2026-3957","OESA-2026-3958","OESA-2026-3959","OESA-2026-3960","OESA-2026-4115","RHSA-2026:54869","UBUNTU-CVE-2026-72522"],"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's Unicode processing by exploiting an out-of-bounds read.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":6.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"libexpat before 2.8.3 has an out-of-bounds read and resultant infinite loop because low surrogates are treated the same as high surrogates during Unicode processing in the *_toUtf16 functions.","ecosystems":["Red Hat:hummingbird:1"],"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-2026-72522","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":3,"n_references":2,"next":{"headline":"Apache Doris: Authorization bypass allowing a low-privilege user to read/write/drop arbitrary tables","id":"CVE-2026-72524"},"packages":[{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.8.3-0.1.hum1"],"introduced":["0"],"last_affected":[],"package":"expat","purl":"pkg:rpm/redhat/expat","source":"RHSA-2026:54869"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.8.3-0.1.hum1"],"introduced":["0"],"last_affected":[],"package":"expat-devel","purl":"pkg:rpm/redhat/expat-devel","source":"RHSA-2026:54869"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.8.3-0.1.hum1"],"introduced":["0"],"last_affected":[],"package":"expat-static","purl":"pkg:rpm/redhat/expat-static","source":"RHSA-2026:54869"}],"prev":{"headline":"Toptech TMS7 and TopHAT SQL Injection","id":"CVE-2026-72510"},"products":["libexpat"],"published":"2026-08-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Red Hat","prefix":"RHSA"},{"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":"2026-08-13","vendors":["libexpat project"]},"summary":"An attacker can cause a denial of service via an infinite loop in libexpat's Unicode processing by exploiting an out-of-bounds read.","url":"https://insights.sbomify.com/CVE-2026-72522/"}
