    Summary: PandaWiki 3.65.0 through 3.87.5 Stored XSS via /static-file/ PDF Query-String Bypass

    Details: PandaWiki 3.65.0 through 3.87.5 contains a stored cross-site scripting vulnerability that allows unauthenticated attackers to upload HTML files with image extensions via /share/v1/common/file/upload. Attackers can lure administrators to /static-file/<key>?a=.pdf, bypassing the nginx attachment header to serve HTML inline and steal the panda_wiki_token JWT for session takeover.
