Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-26072 exists.\n\nAffected product: Atlassian Confluence Data Center. 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-2021-26072/ (Markdown: https://insights.sbomify.com/CVE-2021-26072/index.md)","id":"CVE-2021-26072","markdown":"https://insights.sbomify.com/CVE-2021-26072/index.md","name":"CVE-2021-26072","record":{"aliases":["GHSA-889g-gr2g-424w"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Confluence Server","requires_auth":"low_privilege","summary":"Remote attackers can manipulate internal network resources via blind SSRF in the WidgetConnector plugin, requiring an upgrade to Confluence Server or Data Center.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"atlassian","cpe":[{"product":"confluence_data_center","vendor":"atlassian"},{"product":"confluence_server","vendor":"atlassian"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"The WidgetConnector plugin in Confluence Server and Confluence Data Center before version 5.8.6 allowed remote attackers to manipulate the content of internal network resources via a blind Server-Side Request Forgery (SSRF) vulnerability.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-26072.yaml","stars":null,"title":"Atlassian Confluence \u003c 5.8.6 - Server-Side Request Forgery"}],"tier":"weaponised"},"has_fix":null,"headline":"Server-side request forgery in Confluence Data Center","id":"CVE-2021-26072","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Broken Authentication in Atlassian Connect Express","id":"CVE-2021-26073"},"packages":[],"prev":{"headline":"Cross-site request forgery in Jira Data Center","id":"CVE-2021-26071"},"products":["Confluence Data Center","Confluence Server"],"published":"2021-04-01","related":[{"cvss_score":10,"headline":"Atlassian Confluence Data Center and Server Template Injection","id":"CVE-2023-22527","kev_date_added":"2024-01-24","published":"2024-01-16"},{"cvss_score":10,"headline":"Atlassian Confluence Data Center and Server Improper Authorization","id":"CVE-2023-22518","kev_date_added":"2023-11-07","published":"2023-10-31"},{"cvss_score":10,"headline":"Atlassian Confluence Data Center and Server Broken Access Control","id":"CVE-2023-22515","kev_date_added":"2023-10-05","published":"2023-10-04"},{"cvss_score":9.8,"headline":"Atlassian Confluence Server and Data Center Remote Code Execution","id":"CVE-2022-26134","kev_date_added":"2022-06-02","published":"2022-06-03"},{"cvss_score":9.8,"headline":"Atlassian Confluence Server and Data Center Object-Graph Navigation Language (OGNL) Injection","id":"CVE-2021-26084","kev_date_added":"2021-11-03","published":"2021-08-30"},{"cvss_score":5.3,"headline":"Atlassian Confluence Server Pre-Authorization Arbitrary File Read","id":"CVE-2021-26085","kev_date_added":"2022-03-28","published":"2021-08-03"},{"cvss_score":9,"headline":"Code injection in Confluence Data Center","id":"CVE-2023-22522","kev_date_added":null,"published":"2023-12-06"}],"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":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["Atlassian"]},"summary":"Remote attackers can manipulate internal network resources via blind SSRF in the WidgetConnector plugin, requiring an upgrade to Confluence Server or Data Center.","url":"https://insights.sbomify.com/CVE-2021-26072/"}
