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-2026-21626 in the wild and no public exploit code.\n\nAffected product: Stackideas.com EasyDiscuss 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-2026-21626/ (Markdown: https://insights.sbomify.com/CVE-2026-21626/index.md)","id":"CVE-2026-21626","markdown":"https://insights.sbomify.com/CVE-2026-21626/index.md","name":"CVE-2026-21626","record":{"aliases":["GHSA-xfjv-gcf8-3jqc"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla forum extension","requires_auth":"none","summary":"Attackers can access restricted forum post custom fields via JSON output due to missing access control checks in the EasyDiscuss extension.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[{"product":"easydiscuss","vendor":"stackideas"}],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Access control settings for forum post custom fields are not applied to the JSON output type, leading to an ACL violation vector an information disclosure","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":"Extension - stackideas.com - Information disclosure in post custom fields in EasyDiscuss 1.0.0-5.0.15 for Joomla","id":"CVE-2026-21626","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"SQL injection in Advanced Custom Fields","id":"CVE-2026-21627"},"packages":[],"prev":{"headline":"Extension - stackideas.com - Lack of mime type validation in EasyDiscuss component 1.0.0-5.0.15 for Joomla","id":"CVE-2026-21625"},"products":["EasyDiscuss extension for Joomla"],"published":"2026-02-06","related":[{"cvss_score":9.4,"headline":"Extension - stackideas.com - Persistent XSS in EasyDiscuss component 1.0.0-5.0.15 for Joomla","id":"CVE-2026-21623","kev_date_added":null,"published":"2026-01-16"},{"cvss_score":9.4,"headline":"Extension - stackideas.com - Persistent XSS in EasyDiscuss component 1.0.0-5.0.15 for Joomla","id":"CVE-2026-21624","kev_date_added":null,"published":"2026-01-16"},{"cvss_score":7.5,"headline":"SQL injection in n/a","id":"CVE-2023-51810","kev_date_added":null,"published":"2024-01-16"},{"cvss_score":5.4,"headline":"Cross-site scripting in n/a","id":"CVE-2018-5263","kev_date_added":null,"published":"2018-01-08"},{"cvss_score":4.8,"headline":"Extension - stackideas.com - Lack of mime type validation in EasyDiscuss component 1.0.0-5.0.15 for Joomla","id":"CVE-2026-21625","kev_date_added":null,"published":"2026-01-16"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-02-20","vendors":["Stackideas.com"]},"summary":"Attackers can access restricted forum post custom fields via JSON output due to missing access control checks in the EasyDiscuss extension.","url":"https://insights.sbomify.com/CVE-2026-21626/"}
