{"id":"CVE-2026-16302","state":"PUBLISHED","title":"Spectra Legacy – Gutenberg Blocks  <= 2.20.0 - Authenticated (Contributor+) Sensitive Information Exposure","description":"The Spectra Legacy – Gutenberg Blocks plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.20.0 via the editor_assets function,  which exposes the uag_insta_linked_accounts option through the uagb_blocks_info object without a capability check. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract sensitive data including raw Instagram Graph API access tokens configured by an administrator. Exploitation requires the Spectra Pro plugin to be active with a linked Instagram account.","publishedAt":"2026-09-24T11:31:09.785Z","updatedAt":"2026-09-24T11:57:24.927Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["brainstormforce Spectra Legacy – Gutenberg Blocks"],"affected":[{"vendor":"brainstormforce","product":"Spectra Legacy – Gutenberg Blocks","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.20.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/eede8a1e-db33-4c07-9991-9def75dddc87?source=cve","https://plugins.trac.wordpress.org/changeset/3630074/"],"weaknesses":["CWE-200"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/16xxx/CVE-2026-16302.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-16302","state":"PUBLISHED","datePublished":"2026-09-24T11:31:09.785Z","dateUpdated":"2026-09-24T11:57:24.927Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-20T13:12:38.874Z"},"containers":{"cna":{"title":"Spectra Legacy – Gutenberg Blocks  <= 2.20.0 - Authenticated (Contributor+) Sensitive Information Exposure","descriptions":[{"lang":"en","value":"The Spectra Legacy – Gutenberg Blocks plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.20.0 via the editor_assets function,  which exposes the uag_insta_linked_accounts option through the uagb_blocks_info object without a capability check.
