This is due to insufficient input sanitization in the update_gallery_data() function and improper output escaping in the gallery_init() function. The sanitize_config_values() function only sanitizes the justified_gallery_theme and justified_row_height parameters, but does not sanitize the arrows parameter. When the arrows value is output in the inline JavaScript configuration, it uses esc_attr() which is designed for HTML attribute contexts, not JavaScript contexts, allowing JavaScript expression injection. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page."}],"title":"Envira Gallery <= 1.12.4 - Authenticated (Author+) Stored Cross-Site Scripting via 'arrows' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/d2b1e973-f22d-4e69-b3b8-d6ea5df3f047?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/envira-gallery-lite/trunk/includes/global/shortcode.php#L1067"},{"url":"https://plugins.trac.wordpress.org/browser/envira-gallery-lite/tags/1.12.4/includes/global/shortcode.php#L1067"},{"url":"https://plugins.trac.wordpress.org/browser/envira-gallery-lite/trunk/includes/global/rest.php#L163"},{"url":"https://plugins.trac.wordpress.org/browser/envira-gallery-lite/tags/1.12.4/includes/global/rest.php#L163"},{"url":"https://plugins.trac.wordpress.org/changeset/3514026/envira-gallery-lite/trunk/includes/global/shortcode.php?old=3465371&old_path=envira-gallery-lite%2Ftrunk%2Fincludes%2Fglobal%2Fshortcode.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":"Athiwat Tiprasaharn"},{"lang":"en","type":"finder","value":"Itthidej Aramsri"}],"timeline":[{"time":"2026-04-01T17:36:10.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-05-13T14:42:15.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-05-14T10:39:14.280741Z","id":"CVE-2026-5361","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":"2026-05-14T10:47:27.431Z"}}]}}
