This is due to insufficient input sanitization on meta registration and missing output escaping in the `astra_get_responsive_background_obj()` function for four CSS-context sub-properties (`background-color`, `background-image`, `overlay-color`, `overlay-gradient`). This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page."}],"title":"Astra <= 4.12.3 - Authenticated (Contributor+) Stored Cross-Site Scripting via Post Meta","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/acf2906b-1ee5-4272-bf6d-36a02023f658?source=cve"},{"url":"https://themes.trac.wordpress.org/browser/astra/4.12.3/inc/core/common-functions.php#L1640"},{"url":"https://themes.trac.wordpress.org/browser/astra/4.12.3/inc/core/common-functions.php#L1629"},{"url":"https://themes.trac.wordpress.org/browser/astra/4.12.3/inc/metabox/class-astra-meta-boxes.php#L1386"},{"url":"https://themes.trac.wordpress.org/browser/astra/4.12.3/inc/metabox/class-astra-meta-boxes.php#L1380"},{"url":"https://themes.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=316958%40astra%2F4.12.4&old=312219%40astra%2F4.12.3"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":6.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Alex Hickey"}],"timeline":[{"time":"2026-03-04T17:45:12.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-03-10T17:27:37.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-11T14:00:26.814244Z","id":"CVE-2026-3534","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-03-11T14:00:35.014Z"}}]}}
