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-2016-4881 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- baserproject/basercms (Packagist): affected all versions; fixed in 3.0.11\n- baserproject/basercms (Packagist): affected all versions; fixed in 3.0.11\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-2016-4881/ (Markdown: https://insights.sbomify.com/CVE-2016-4881/index.md)","id":"CVE-2016-4881","markdown":"https://insights.sbomify.com/CVE-2016-4881/index.md","name":"CVE-2016-4881","record":{"aliases":["GHSA-46vm-rwrf-jrxm"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"baserCMS Blog plugin","requires_auth":"none","summary":"Remote attackers can hijack administrator sessions in the baserCMS Blog plugin via cross-site request forgery.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"basercms","vendor":"basercms"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Cross-site request forgery (CSRF) vulnerability in baserCMS plugin Blog version 3.0.10 and earlier allows remote attackers to hijack the authentication of administrators via unspecified vectors.","ecosystems":["Packagist"],"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":"CSRF in baserCMS 3.0.10 and earlier","id":"CVE-2016-4881","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"basercms:basercms","products":["basercms:basercms"],"type":"csrf","year":"2016"},"n_packages":2,"n_references":3,"next":{"headline":"Cross-site request forgery in baserCMS","id":"CVE-2016-4882"},"packages":[{"ecosystem":"Packagist","fixed":["3.0.11"],"introduced":["0"],"last_affected":[],"package":"baserproject/basercms","purl":null,"source":"GHSA-46vm-rwrf-jrxm"},{"ecosystem":"Packagist","fixed":["3.0.11"],"introduced":["0"],"last_affected":[],"package":"baserproject/basercms","purl":"pkg:composer/baserproject/basercms","source":"GHSA-46vm-rwrf-jrxm"}],"prev":{"headline":"baserCMS Cross-site Scripting vulnerability","id":"CVE-2016-4880"},"products":["baserCMS plugin Blog"],"published":"2017-05-12","related":[{"cvss_score":9.8,"headline":"baserCMS File Uploader Remote Code Execution (RCE) vulnerability","id":"CVE-2023-25654","kev_date_added":null,"published":"2023-03-23"},{"cvss_score":9.8,"headline":"baserCMS allows any file to be uploaded","id":"CVE-2023-25655","kev_date_added":null,"published":"2023-03-23"},{"cvss_score":9.8,"headline":"baserCMS SQL Injection vulnerability","id":"CVE-2017-10842","kev_date_added":null,"published":"2017-08-28"},{"cvss_score":9.2,"headline":"baserCMS: OS command injection vulnerability in installer","id":"CVE-2026-30880","kev_date_added":null,"published":"2026-03-31"},{"cvss_score":9.1,"headline":"baserCMS: OS Command Injection Leading to Remote Code Execution (RCE)","id":"CVE-2026-21861","kev_date_added":null,"published":"2026-03-31"},{"cvss_score":9.1,"headline":"baserCMS: OS Command Injection in the baserCMS Update Functionality","id":"CVE-2026-30877","kev_date_added":null,"published":"2026-03-31"},{"cvss_score":9.1,"headline":"OS Command Injection Vulnerability and Potential Zip Slip Vulnerability","id":"CVE-2021-41243","kev_date_added":null,"published":"2021-11-26"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["baserCMS Users Community"]},"summary":"Remote attackers can hijack administrator sessions in the baserCMS Blog plugin via cross-site request forgery.","url":"https://insights.sbomify.com/CVE-2016-4881/"}
