Robo Gallery: A security weakness

A Contributor can save script-bearing gallery settings that are rendered without sufficient escaping when an administrator edits the gallery. This permits stored JavaScript execution in the administrator’s browser. The export does not name the setting, save action or rendering function; its PR:H vector differs from the Contributor role specified in the narrative. Affected versions: < 5.2.6. The authoritative export identifies 5.2.6 as fixed for this CVE.

CWE-79 — Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

This CVE was published Oct 11, 2026 and is one of 22 known issues for this plugin.

Update, patch or deactivate.

Update to 5.2.6 or a later supported release. Application-level remediation: Validate stored and request values and escape them for their final HTML, attribute, URL or JavaScript context. Enforce capability and object-ownership checks on settings and content writes.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Technical description

The Robo Gallery WordPress plugin before 5.2.6 does not sanitise and escape some of its gallery settings before outputting them on the gallery edit screen, allowing users with the Contributor role and above to store JavaScript that executes in the context of an administrator who opens the gallery for editing.
