CVE-2024-27136Network attack vector

Browser script execution via crafted upload request

Published Jun 24, 2024 · Updated Mar 20, 2025

Cross-site scripting in Apache JSPWiki 2.12.1 and earlier allows remote attackers to execute JavaScript in a victim's browser via Upload requests. Apache identifies the Upload page and a carefully crafted request but has not disclosed the precise input, rendering sink, or failed neutralization operation. Exploitation requires the victim's browser to process the crafted response and allows script execution and sensitive-information disclosure in that browser context.
