Deeper analysis

CVE-2024-27136 is a cross-site scripting vulnerability (CWE-79) affecting the Upload page in Apache JSPWiki versions 2.12.1 and earlier. The flaw permits injection of JavaScript that executes in a victim's browser, with a CVSS 3.1 base score of 6.1 reflecting network attack vector, low complexity, no required privileges, and required user interaction.

An unauthenticated remote attacker can exploit the issue by crafting a malicious request that triggers script execution when a victim visits the Upload page, enabling theft of sensitive browser-resident information such as cookies or session tokens.
