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-2026-73633 in the wild and no public exploit code.\n\nAffected product: Apache Struts. 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-2026-73633/ (Markdown: https://insights.sbomify.com/CVE-2026-73633/index.md)","id":"CVE-2026-73633","markdown":"https://insights.sbomify.com/CVE-2026-73633/index.md","name":"CVE-2026-73633","record":{"aliases":["GHSA-335q-cpqh-m68h"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Java web framework","requires_auth":"none","summary":"Attackers can cause denial of service by sending large JSON requests to Apache Struts applications using the optional JSON plugin.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"struts","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-400","name":"Uncontrolled Resource Consumption"}],"description":"Uncontrolled resource consumption vulnerability in the JSON plugin of Apache Struts. When an application is configured to populate actions from a JSON request body, the plugin reads that body into memory without bounding how much it will accept, so a single request can exhaust the heap and deny service to other users. The plugin's configurable JSON input length limit does not bound this read. The JSON plugin is an optional component; applications that do not use it, or use it without enabling JSON request-body handling, are not affected.\n\nThis issue affects Apache Struts: from 2.1.8 through 2.3.37, from 2.5.0 through 2.5.33, from 6.0.0 through 6.10.0, from 7.0.0 through 7.2.1.\n\nUsers are recommended to upgrade to version 6.11.0 or 7.3.0, which fixes the issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-08-16","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-08-16T11:30:03Z","kind":"github_poc","ref":"https://github.com/CuteeCat/CVE-2026-73633","stars":0,"title":"CVE-2026-73633（S2-072）概念验证代码"}],"tier":"poc_unverified"},"has_fix":false,"headline":"Apache Struts: Unbounded read of a JSON request body","id":"CVE-2026-73633","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apache:struts","products":["apache:struts"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Struts: Unbounded read of a Content Security Policy violation report","id":"CVE-2026-73634"},"packages":[],"prev":{"headline":"Apache Struts: Shared serialization state in the JSON plugin","id":"CVE-2026-73632"},"products":["Apache Struts"],"published":"2026-08-14","related":[{"cvss_score":9.8,"headline":"Apache Struts Remote Code Execution","id":"CVE-2020-17530","kev_date_added":"2021-11-03","published":"2020-12-11"},{"cvss_score":9.8,"headline":"Apache Struts 1 Improper Input Validation","id":"CVE-2017-9791","kev_date_added":"2022-02-10","published":"2017-07-10"},{"cvss_score":9.8,"headline":"Apache Struts Remote Code Execution","id":"CVE-2017-5638","kev_date_added":"2021-11-03","published":"2017-03-11"},{"cvss_score":9.8,"headline":"Apache Struts 2 Improper Input Validation","id":"CVE-2012-0391","kev_date_added":"2022-01-21","published":"2012-01-08"},{"cvss_score":8.1,"headline":"Apache Struts Remote Code Execution","id":"CVE-2018-11776","kev_date_added":"2021-11-03","published":"2018-08-22"},{"cvss_score":8.1,"headline":"Apache Struts Deserialization of Untrusted Data","id":"CVE-2017-9805","kev_date_added":"2021-11-03","published":"2017-09-15"},{"cvss_score":8.1,"headline":"Apache Struts Command Injection","id":"CVE-2016-3081","kev_date_added":"2026-10-08","published":"2016-04-26"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-14","vendors":["Apache Software Foundation"]},"summary":"Attackers can cause denial of service by sending large JSON requests to Apache Struts applications using the optional JSON plugin.","url":"https://insights.sbomify.com/CVE-2026-73633/"}
