CVE-2026-48823

Shaarli is a personal bookmarking service. Versions 0.16.1 and prior contain a stored Cross-Site Scripting (XSS) vulnerability in the tag filtering functionality of Shaarli. An authenticated user can inject arbitrary JavaScript into the tags field when creating a bookmark (Shaare). The malicious payload is stored and later executed when users interact with the "Filter by tag" search feature on the homepage. User-supplied input in the tags field is not properly sanitized or output-escaped before
