Published: 2026-09-24 · CVSS: 4.3 · CVSS 3.1
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.
