🐘leantime/leantime

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

Leantime allows stored cross-site scripting (XSS) in the API key name while generating the API key.

Impact

Any low privileged user like manager, or editor, can create an API key with XSS payload. When admin will visit the Company page, the XSS will automatically get triggerred leading to the unauthorized action performed from the ADMIN account. Like, removing any user, or adding someone else as high privilege, and many more.
