Summary

Duplicate Advisory: Grav: detectXss() misses an event-handler attribute after an unpaired quote in an unquoted attribute value, giving stored XSS

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-vfmf-q6x9-cw96. This link is maintained to preserve external references.

Original Description

Grav before 2.0.15 contains a stored cross-site scripting vulnerability in the detectXss() function where unpaired quotes in unquoted attribute values bypass event-handler detection. Authenticated editors can inject event handlers like onerror= that pass validation and execute in visitor browsers when page content is rendered.
