An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-19202 in the wild and no public exploit code.\n\nAffected product: Mybb Mybb. 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-2018-19202/ (Markdown: https://insights.sbomify.com/CVE-2018-19202/index.md)","id":"CVE-2018-19202","markdown":"https://insights.sbomify.com/CVE-2018-19202/index.md","name":"CVE-2018-19202","record":{"aliases":["GHSA-2g9j-9x3c-w748"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"MyBB forum software","requires_auth":"none","summary":"Remote attackers can inject JavaScript via the upsetting[bburl] parameter in MyBB, potentially leading to session hijacking or malicious actions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mybb","vendor":"mybb"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A reflected XSS vulnerability in index.php in MyBB 1.8.x through 1.8.19 allows remote attackers to inject JavaScript via the 'upsetting[bburl]' parameter.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cross-site scripting in n/a","id":"CVE-2018-19202","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mybb:mybb","products":["mybb:mybb"],"type":"xss","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Denial of service in n/a","id":"CVE-2018-19203"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-19201"},"products":["n/a"],"published":"2019-04-11","related":[{"cvss_score":10,"headline":"myBB 1.6.4 Backdoor Arbitrary Command Execution","id":"CVE-2011-10018","kev_date_added":null,"published":"2025-08-13"},{"cvss_score":10,"headline":"Information disclosure in n/a","id":"CVE-2015-2786","kev_date_added":null,"published":"2015-03-29"},{"cvss_score":10,"headline":"Cross-site scripting in n/a","id":"CVE-2011-5133","kev_date_added":null,"published":"2012-08-30"},{"cvss_score":10,"headline":"SQL injection in n/a","id":"CVE-2006-0218","kev_date_added":null,"published":"2006-01-16"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2020-22612","kev_date_added":null,"published":"2023-09-01"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2017-16780","kev_date_added":null,"published":"2017-11-10"},{"cvss_score":8.8,"headline":"SQL injection in n/a","id":"CVE-2021-27890","kev_date_added":null,"published":"2021-03-15"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can inject JavaScript via the upsetting[bburl] parameter in MyBB, potentially leading to session hijacking or malicious actions.","url":"https://insights.sbomify.com/CVE-2018-19202/"}
