Description

CVE-2025-12544 is a cross-site scripting (XSS) vulnerability in the WSO2 API Manager Publisher portal. It arises from improper validation of uploaded SVG files, allowing users with the Publisher role to inject malicious scripts. Exploitation can lead to browser redirection, UI manipulation, or information disclosure, though session hijacking is mitigated by httpOnly cookie flags. The vulnerability affects multiple versions prior to specific fixed releases and has a medium severity rating.
