CVE-2022-45358Network attack vector

Subscriber-level script execution via reflected web input

Published Apr 13, 2023 · Updated Apr 28, 2026

Reflected cross-site scripting in Silkalns Activello 1.4.4 and earlier allows remote authenticated users to run script via crafted requests. Patchstack has not disclosed the affected parameter, template, or function; the public record establishes only that input is reflected into web output without proper neutralization. Subscriber-level access and a victim following a crafted link are required; successful exploitation runs script in the victim's browser under the site's origin.
