This is due to a bypassable security filter (bt_bb_save_pre) that can be circumvented via null byte injection, combined with insufficient output sanitization of base64-decoded content in the bt_bb_raw_content shortcode handler. 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":"Bold Page Builder <= 5.9.6 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'shortcode_content' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/629fee36-1fea-4a4d-acc2-9ba18d0b6487?source=cve"},{"url":"https://plugins.trac.wordpress.org/changeset/3668982/bold-page-builder/trunk/content_elements/bt_bb_raw_content/bt_bb_raw_content.php"}],"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":"suyoung kim(AhnLab)"}],"timeline":[{"time":"2026-04-03T00:00:00.000Z","lang":"en","value":"Discovered"},{"time":"2026-08-05T08:40:18.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-09-15T15:39:37.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-16T18:55:55.503085Z","id":"CVE-2026-5920","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":"2026-09-16T18:56:05.108Z"}}]}}
