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-2026-91863 in the wild and no public exploit code.\n\nAffected product: Apache Neethi. 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-2026-91863/ (Markdown: https://insights.sbomify.com/CVE-2026-91863/index.md)","id":"CVE-2026-91863","markdown":"https://insights.sbomify.com/CVE-2026-91863/index.md","name":"CVE-2026-91863","record":{"aliases":["GHSA-wr93-w764-3636"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java WS-Policy library","requires_auth":"none","summary":"Attackers can cause denial of service by sending crafted WS-Policy documents that trigger uncontrolled recursion and stack exhaustion in Apache Neethi.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"neethi","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-674","name":"Uncontrolled Recursion"}],"description":"A specially crafted WS-Policy document with deeply nested policy elements can bypass Neethi's nesting-depth limit and exhaust the thread stack, crashing the parser (denial of service).\nUsers are recommended to upgrade to version 3.2.4, which fixes this issue.","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":"Apache Neethi: Uncontrolled recursion while parsing crafted WS-Policy documents allows denial of service","id":"CVE-2026-91863","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Neethi: Crafted WS-Policy documents bypass element/attribute limits causing memory exhaustion","id":"CVE-2026-91864"},"packages":[],"prev":{"headline":"Getwid \u003c= 3.0.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'data-image-points'","id":"CVE-2026-91862"},"products":["Apache Neethi"],"published":"2026-09-21","related":[{"cvss_score":7.5,"headline":"Apache Neethi: Crafted WS-Policy documents bypass element/attribute limits causing memory exhaustion","id":"CVE-2026-91864","kev_date_added":null,"published":"2026-09-21"},{"cvss_score":7.5,"headline":"Apache Neethi: Crafted policy references cause exponential expansion during normalization leading to denial of service","id":"CVE-2026-91865","kev_date_added":null,"published":"2026-09-21"},{"cvss_score":7.5,"headline":"Apache Neethi: Crafted policies cause unbounded work during intersection leading to denial of service","id":"CVE-2026-91866","kev_date_added":null,"published":"2026-09-21"},{"cvss_score":7.5,"headline":"Apache Neethi: Uncontrolled recursion in policy processing","id":"CVE-2026-66142","kev_date_added":null,"published":"2026-07-24"},{"cvss_score":7.5,"headline":"Apache Neethi: Missing global alternative-output budget across policy computation paths","id":"CVE-2026-66143","kev_date_added":null,"published":"2026-07-24"},{"cvss_score":7.5,"headline":"Apache Neethi: Remote PolicyReference fetch lacks resource bounds","id":"CVE-2026-66144","kev_date_added":null,"published":"2026-07-24"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-21","vendors":["Apache Software Foundation"]},"summary":"Attackers can cause denial of service by sending crafted WS-Policy documents that trigger uncontrolled recursion and stack exhaustion in Apache Neethi.","url":"https://insights.sbomify.com/CVE-2026-91863/"}
