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-2026-65888 in the wild and no public exploit code.\n\nAffected product: balbooa.com Gridbox extension for Joomla. 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-2026-65888/ (Markdown: https://insights.sbomify.com/CVE-2026-65888/index.md)","id":"CVE-2026-65888","markdown":"https://insights.sbomify.com/CVE-2026-65888/index.md","name":"CVE-2026-65888","record":{"aliases":["GHSA-84gf-cfmw-8qqq"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla Gridbox extension","requires_auth":"none","summary":"Attackers can bypass authentication to log in as any user on sites using the Gridbox Joomla extension, leading to account takeover.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[{"product":"gridbox","vendor":"balbooa"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:A/AU:Y/U:Red","version":"4.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Joomla Extension - balbooa.com - Account takeover vulnerability in Gridbox \u003c 2.20.2 - The socialLogin method allows actors to login as any given user on the target site.","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":"Joomla Extension - balbooa.com - Account takeover vulnerability in Gridbox \u003c 2.20.2","id":"CVE-2026-65888","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Joomla Extension - balbooa.com - Unauthenticated recursive directory deletion in Gridbox \u003c 2.20.2","id":"CVE-2026-65889"},"packages":[],"prev":{"headline":"Joomla Extension - balbooa.com - Unauthenticated arbitrary password reset in Gridbox \u003c 2.20.2","id":"CVE-2026-65887"},"products":["Gridbox extension for Joomla"],"published":"2026-07-29","related":[{"cvss_score":10,"headline":"Joomla Extension - balbooa.com - Privilege Escalation in Gridbox \u003c 2.20.2","id":"CVE-2026-65884","kev_date_added":null,"published":"2026-07-29"},{"cvss_score":10,"headline":"Joomla Extension - balbooa.com - Unauthenticated arbitrary password reset in Gridbox \u003c 2.20.2","id":"CVE-2026-65887","kev_date_added":null,"published":"2026-07-29"},{"cvss_score":9.4,"headline":"Joomla Extension - balbooa.com - Authenticated arbitrary file upload in Gridbox \u003c 2.20.2","id":"CVE-2026-65885","kev_date_added":null,"published":"2026-07-29"},{"cvss_score":9.2,"headline":"Joomla Extension - balbooa.com - Unauthenticated arbitrary file read in Gridbox \u003c 2.20.2","id":"CVE-2026-65886","kev_date_added":null,"published":"2026-07-29"},{"cvss_score":9.2,"headline":"Joomla Extension - balbooa.com - Unauthenticated recursive directory deletion in Gridbox \u003c 2.20.2","id":"CVE-2026-65889","kev_date_added":null,"published":"2026-07-29"},{"cvss_score":9.2,"headline":"Joomla Extension - balbooa.com - Unauthenticated SQL injection in Gridbox \u003c 2.20.2","id":"CVE-2026-65890","kev_date_added":null,"published":"2026-07-29"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-12","vendors":["balbooa.com"]},"summary":"Attackers can bypass authentication to log in as any user on sites using the Gridbox Joomla extension, leading to account takeover.","url":"https://insights.sbomify.com/CVE-2026-65888/"}
