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-2023-26119 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- net.sourceforge.htmlunit:htmlunit (Maven): affected all versions; fixed in 3.0.0\n- net.sourceforge.htmlunit:htmlunit (Maven): affected all versions; fixed in 3.0.0\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-2023-26119/ (Markdown: https://insights.sbomify.com/CVE-2023-26119/index.md)","id":"CVE-2023-26119","markdown":"https://insights.sbomify.com/CVE-2023-26119/index.md","name":"CVE-2023-26119","record":{"aliases":["CLSA-2025-1766534901","GHSA-3xrr-7m6p-p7xh","ROOT-APP-MAVEN-CVE-2023-26119"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Java HTMLUnit library","requires_auth":"none","summary":"Attacker can execute arbitrary code via XSTL when browsing a malicious webpage using the HTMLUnit library.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"htmlunit","vendor":"htmlunit"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Versions of the package net.sourceforge.htmlunit:htmlunit from 0 and before 3.0.0 are vulnerable to Remote Code Execution (RCE) via XSTL, when browsing the attacker’s webpage.","ecosystems":["Maven"],"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":"HtmlUnit Code Injection vulnerability","id":"CVE-2023-26119","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"code_injection","year":"2023"},"n_packages":2,"n_references":3,"next":{"headline":"XXL-JOB vulnerable to Cross-site Scripting","id":"CVE-2023-26120"},"packages":[{"ecosystem":"Maven","fixed":["3.0.0"],"introduced":["0"],"last_affected":[],"package":"net.sourceforge.htmlunit:htmlunit","purl":null,"source":"GHSA-3xrr-7m6p-p7xh"},{"ecosystem":"Maven","fixed":["3.0.0"],"introduced":["0"],"last_affected":[],"package":"net.sourceforge.htmlunit:htmlunit","purl":"pkg:maven/net.sourceforge.htmlunit/htmlunit","source":"GHSA-3xrr-7m6p-p7xh"}],"prev":{"headline":"angular vulnerable to regular expression denial of service via the \u003cinput type=\"url\"\u003e element","id":"CVE-2023-26118"},"products":["net.sourceforge.htmlunit:htmlunit"],"published":"2023-04-03","related":[{"cvss_score":9.8,"headline":"HtmlUnit vulnerable to Remote Code Execution (RCE) via XSTL","id":"CVE-2023-49093","kev_date_added":null,"published":"2023-12-04"},{"cvss_score":7.5,"headline":"Denial of service in HtmlUnit","id":"CVE-2023-2798","kev_date_added":null,"published":"2023-05-25"},{"cvss_score":7.5,"headline":"OutOfMemory Exception by specifically crafted processing instruction in NekoHtml Parser","id":"CVE-2022-29546","kev_date_added":null,"published":"2022-04-25"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"total"},"state":"PUBLISHED","updated":"2026-10-08","vendors":["n/a"]},"summary":"Attacker can execute arbitrary code via XSTL when browsing a malicious webpage using the HTMLUnit library.","url":"https://insights.sbomify.com/CVE-2023-26119/"}
