{"id":"CVE-2026-73326","summary":"CamaleonCMS Missing Authorization via Plugin Administration Endpoints","details":"CamaleonCMS contains a missing authorization vulnerability that allows any authenticated low-privileged user to access and modify plugin settings by reaching four unprotected plugin-administration endpoints without administrator-level authorization. Attackers can manipulate plugin configuration parameters at runtime across the attack, front_cache, cama_meta_tag, and cama_contact_form plugins to alter cached page behavior, modify public meta-tag output, or reconfigure contact forms, enabling account takeover when chained with stored cross-site scripting through the contact form's before_html field.","modified":"2026-08-15T04:06:52.045023707Z","published":"2026-08-12T19:13:28.587Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73326.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-862"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73326.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73326"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/camaleoncms-missing-authorization-via-plugin-administration-endpoints"},{"type":"FIX","url":"https://github.com/owen2345/camaleon-cms"},{"type":"ARTICLE","url":"https://enrik-m.github.io/posts/Camaleon-CMS-Vulnerabilties/#31-broken-access-control-on-admin-endpoints"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/owen2345/camaleon-cms","events":[{"introduced":"0"},{"last_affected":"cc71e01c909c9e7fa23ddc115981773ce1242b49"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"2.9.1"}],"source":"AFFECTED_FIELD"}}],"versions":["2.9.1","2.9.0","2.8.3","2.8.2","2.8.1","2.8.0","2.7.5","2.7.4","2.7.3","2.7.1","2.7.0","2.6.4","2.6.2","2.6.1","2.6.0.1","2.6.0","2.5.3.1","2.5.3","2.5.1","2.4.6.7","2.4.6.1","2.4.6.0","2.4.5.14","2.4.5.13","2.4.5.12","camaleon_cms-2.4.5.11.gem","2.4.5.11","2.4.5.10","2.4.5.7","2.4.5.1","2.4.5","2.4.4.6","2.4.4.5","2.4.4.3","2.4.4.2","2.4.4","2.4.3.12","2.4.3.11","2.4.3.10","2.4.3.7","2.4.3","2.4.2","2.4.1","2.4.0","2.3.7","2.3.6","2.3.5","2.3.4","2.3.3","2.3.2","2.3.1","2.2.0","2.1.2.0","v2.1.1.3","2.1.2","2.1.1","v2.0.0","0.2.0","0.1.7"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-73326.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N"}]}
