## Technical details

The vulnerability stems from insufficient sanitization and encoding in the "Nombre" field of the /PlantillasPdf/Edit endpoint, allowing authenticated attackers to store JavaScript payloads that execute in other users' browsers. This is one of multiple stored XSS flaws affecting different modules within ALO Suite (CVE-2026-108050 through CVE-2026-108060), each in different components and fields. Successful exploitation requires authenticated access and user interaction to view the affected record, after which the injected code runs in the victim's session context.
