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-2021-43956 in the wild and no public exploit code.\n\nAffected product: Atlassian Crucible. 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-2021-43956/ (Markdown: https://insights.sbomify.com/CVE-2021-43956/index.md)","id":"CVE-2021-43956","markdown":"https://insights.sbomify.com/CVE-2021-43956/index.md","name":"CVE-2021-43956","record":{"aliases":["GHSA-9p4g-cjcf-q3x2"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Atlassian Crucible/Fisheye","requires_auth":"none","summary":"Remote attackers can inject arbitrary HTML or JavaScript via prototype pollution in the jQuery deserialize library, affecting Atlassian Crucible and Fisheye.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"atlassian","cpe":[{"product":"crucible","vendor":"atlassian"},{"product":"fisheye","vendor":"atlassian"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"The jQuery deserialize library in Fisheye and Crucible before version 4.8.9 allowed remote attackers to to inject arbitrary HTML and/or JavaScript via a prototype pollution vulnerability.","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 Crucible","id":"CVE-2021-43956","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"atlassian:crucible","products":["atlassian:crucible","atlassian:fisheye"],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Path traversal in Crucible","id":"CVE-2021-43957"},"packages":[],"prev":{"headline":"Information disclosure in Crucible","id":"CVE-2021-43955"},"products":["Crucible","Fisheye"],"published":"2022-03-16","related":[{"cvss_score":9.8,"headline":"Security feature bypass in Crucible","id":"CVE-2021-43958","kev_date_added":null,"published":"2022-03-16"},{"cvss_score":9.8,"headline":"Code injection in Fisheye and Crucible","id":"CVE-2017-16861","kev_date_added":null,"published":"2018-02-01"},{"cvss_score":9,"headline":"Command injection in Fisheye and Crucible","id":"CVE-2017-14591","kev_date_added":null,"published":"2017-11-29"},{"cvss_score":8.8,"headline":"Cross-site request forgery in Crucible","id":"CVE-2020-4018","kev_date_added":null,"published":"2020-06-01"},{"cvss_score":7.8,"headline":"Privilege escalation in Fisheye and Crucible","id":"CVE-2018-13399","kev_date_added":null,"published":"2018-10-16"},{"cvss_score":7.5,"headline":"Path traversal in Crucible","id":"CVE-2021-43957","kev_date_added":null,"published":"2022-03-16"},{"cvss_score":7.5,"headline":"Denial of service in Crucible","id":"CVE-2020-14190","kev_date_added":null,"published":"2020-11-25"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-03","vendors":["Atlassian"]},"summary":"Remote attackers can inject arbitrary HTML or JavaScript via prototype pollution in the jQuery deserialize library, affecting Atlassian Crucible and Fisheye.","url":"https://insights.sbomify.com/CVE-2021-43956/"}
